How often do we update our paper maps?

I’m told by my colleagues in the customer service team that one of the most common questions we’re asked is ‘how often do you update your paper maps?’

It’s a very good question.

But there isn’t a ‘one size fits all’ answer. The frequency depends on a combination of factors, the primary one being the amount of change that needs to be applied to the map since it was previously revised.

The popularity of the sheet is also a factor. A map covering an area popular with vistors such as the Lake District would take priority over a less-popular area, providing of course, that changes have occurred that would be important to the users – new footpaths, roads and a visitor centre for example.

New editions are then released when our stocks of a superseded edition run out. So for a popular area, like The Lakes, that might be a lot sooner than for less popular locations.

This helps minimise the financial and environmental costs in having to scrap any unsold superseded editions both for us, our wholesalers and for retailers, who don’t have to manage the turnover of editions.

What about when there’s a mistake on a map?

As hard as it is to imagine, yes occasionally we do make mistakes on our maps for which we’re always apologetic. Accuracy is our business, but when you’re mapping the whole country errors do occasionally occur. Generally when we’re told of a mistake, we make sure it’s logged and the next time that map sheet is revised, the mistake is corrected alongside any changes to the landscape that might have occurred.

However, each mistake is looked at individually and sometimes we will decide to correct the error in our digital data before the next revision of the paper map. In this instance it means that’s OS OpenData, OS OpenSpace, OS Select, OS Getamap and the 1:25,000 scale or 1:50,000 scale raster products will be correct the next time the data is refreshed – typically every six months in May and November.

I hope all that makes sense but if you do have any questions, just leave a comment and we’ll do our best to answer them!

  1. A question I am forever asked is ‘how often is the OSMM updated as there lots of changes over the past ‘n’ years that aren’t on the map of my village’. I understand that there is a threshold of changes to a 1km tile before an update takes place, is this correct and if so what is the threshold? Regards, Ian

  2. Hi Ian,

    Change intelligence (i.e. knowing about where the real world has changed) is absolutely key to what we do. We invest heavily in our change intelligence data and use data from several sources to help us keep our detailed mapping current.

    Our most detailed data, like OS MasterMap Topography Layer, is updated using two revision programmes that run alongside each other:

    Continuous revision – this programme is primarily concerned with the maintenance and new survey of significant features. This fundamental activity ensures important features are kept up-to date in all parts of the country.

    The key method that we use is ground survey, underpinned by state of the art GPS equipment. We use several sources of intelligence to identify change on the ground including new buildings, demolitions and major changes to existing real-world features.

    Our aim is to ensure that significant real-world features are represented in our data within six months of their completion on the ground.

    Cyclic revision – To complement our Continuous Revision programme, we also run a programme of cyclic revision which based on systematic revision of ‘rural’ and ‘mountain and moorland’ geographies using aerial photography.

    Every part of the country is systematically inspected for change at least every 5 years to ensure that changes on the ground are reflected in our core database – around 20% of Great Britain is revised every year under this programme.

    Having said that, with half a billion features in our data we do occasionally miss things and as such we are always happy to receive feedback when people find changes that are not reflected in our mapping.

    This can always be fed back to our customer contact centre, just email customerservices@ordnancesurvey.co.uk

    I hope this helps.

      Hi Paul
      I don’t know if you can answer a question regarding revisions of Ordnance Survey Maps in the nineteenth century. I have a map of Stockport with the mapping survey having been carried out in 1849, the map published in 1851 and revised in 1873. There is one street in particular that I am interested in. The 1851 census lists houses on the street, but they do not feature on the map. I believe the houses were built in 1850, after the survey, but well before the revision. Would the case have also been that in Victorian Times, revisions to maps may have also been limited to certain features? This would explain the absence of a half of a street! At the same time, would this mean that this map(like, I suppose, other OS maps) wasn’t completely accurate at the date of revision, but accurate only within a range of years, that is, 1849 – 1873? Best wishes, Ralph.

      1. Gemma

        Hi Ralph
        From the information you’ve given us, we can say that the first Ordnance Survey mapping of Stockport (Cheshire) was circa 1848 at 6″ to 1 Mile (1:10560), which was a part County Series ‘edge’ sheet of the Lancashire and Furness County Series. This was closely followed by a “Town Plan” of Stockport at 1:1056 (sic) scale (60″/ 5 feet to 1 Mile) surveyed in 1851. These were called Sanitation Plans as they were intended to support the work required to bring public heath and sanitation (sewers, drains and clean water supplies to urban areas). The plan was revised in 1873.

        These early surveys were undertaken during the “Battle of the Scales” when there was a period when first surveys were being undertaken at the 6″ scale in preference to the 1″ scale, but before the formal decisions on a full range of scales including 1:500; 1,2500, 6″ (1:10,560) and 1″ (1:63,360).

        Without knowing the exact location of the street you’re referring to to it is difficult to conjecture why the revision of 1873 covered only part of it. We do know that revision of Town Plans in the later Victorian period was often at the expense of the civic authority, but we can’t say if that was the case in Stockport in 1873, and if so whether there was selectivity in what was revised.

        We may be able to provide you with some further information if you let us know the scale of your map and the road name you are interested in.
        Many thanks, Gemma

          Hi Gemma

          Thank you for the prompt reply and the background information.

          The street was Ratcliffe Street which ran from Wellington Road South to Middle Hillgate. A stub of the street remains, leading off Wellington Road South.

          The enumerator (1851 Census: Cheshire – Stockport – District 3f) listed houses on Ratcliffe Street with numbers from 6 to 110 on side and from 1 to 33 on the other.

          The map I have is a reproduction, entitled ‘Stockport Town Centre 1873’, and is “reduced from the original Ordnance Survey 1:1,056 map”.

          Hope this helps. If you can come up with any further ideas, then that would be much appreciated.

          Regards

          Ralph

    I was wondering if it is possible to find out when a specific map is scheduled for an update? I wanted to buy the paper explorer map 190 but the one in our local shop was last updated 3 years ago.

    1. Tim Brunton

      Hi
      I have put together a new, coast to coast, Macmillan Way which is now in your system waiting to go onto OS mapping. It crosses Landranger sheets 124 to 131(inclusive), plus 137 and 138. The question is, would you know when any of the above is scheduled for an update as I would love to see the path finally on the map.
      Thanks in advance

      1. Hi

        We’ve passed this along to our Cartography team to check on the timescales. We’ll get back to you once we hear from them.

        Thanks, Gemma

      2. Hi Tim

        We’ve heard back from our Cartography team now. All of the OS Landranger sheets you mentioned – 124 to 131, 137 and 138 – are in the current sheet revision programme for the team. The first of the sheets should be available in the summer 2017 with further publications of the other titles to follow, completion of all the sheets should be by summer 2018. However, we cannot give more specific dates for any individual map sheet, due to the dynamic nature of our revision programme.

        Although we cannot be more specific at this stage, if you would like to contact us in six months’ time, we will be able to provide details of which sheets have already been revised, and may be better placed to provided dates for the remaining sheets.

        As soon as a revised sheet is published, it will be available to purchase from our online shop: https://www.ordnancesurvey.co.uk/shop/maps.html.

        Many thanks
        Gemma

        1. Tim Brunton

          Hi Gemma
          CROSS BRITAIN WAY
          Thanks for your detailed reply on 3rd March. It has only just occurred to me I never responded for which I apologise.
          If there have been any revisions completed I would be very interested to hear, but appreciate it is probably a bit early yet, in which case I will enquire again around the end of August as you indicated.
          Kind regards

          Tim Brunton

    Hi Birling, Both maps, the OS Landranger 152 (Northampton & Milton Keynes) and OS Explorer 223 (Northampton & Market Harborough) were last updated in 2009 and there are no plans to update them in the coming year.

    We update depending on the amount of change which takes place in the area as Paul explains above. However, you can tell when it was printed by looking at the legend on the map.

      1. Gemma

        Huge apologies Roger, this one had been missed. I’ve just found out that a reprint for minor correction was published in the last month for this map. The version number on the map for the reprint will be A2_
        The previous 2008 edition will have a version number of A2
        Many thanks, Gemma

    1. Gemma

      Hi Mick
      Yes that is the current one and there are no plans to revise it in the next year as there is little recorded change to be applied to the sheet.
      Enjoy getting outdoors with your map!
      Thanks, Gemma

  5. Kieran

    How do I report errors? – I use OS Explorer 160 for navigation with Scouts on Horsell Common & some significant (and mature) bridleways are not marked on the map as well as variations in many minor paths. These errors exist on both paper and online versions & I would really like to help get the online version updated.

    1. Gemma

      Hi Kieran
      Could you contact our Customer Service Centre on 08456 050505 as they’re best placed to discuss this with you.
      Thanks, Gemma

  6. Kay

    Hi can you help.

    According to Fife Council (Scotland), Planning Dept, they stated that it is not their responsibility to inform OS of the changes of property numbers. They said it was Royal Mail’s responsibility. Is this correct?

    The reason I ask is that if you look at Fife Council website link, it clearly sates that Fife Council is responsible for property number changes. So, is it not their responsibility to pass the updated information onto the OS, so the OS can update their maps accordingly? Here is the Fife Council link:-
    http://www.fifedirect.org.uk/topics/index.cfm?fuseaction=service.display&p2sid=FE858E04-FE16-D92D-A3352BB0E4D33BE4&themeid=2B482E89-1CC4-E06A-52FBA69F838F4D24

    The OS maps are a very useful tool when buying property, as the property Title Deeds come with an OS map, and if that is outdated, then the information in the Title Deeds can be outdated as it will may not correspond with the allocation of neighbouring properties. This would affect Access Rights, etc.

    If you able to provide me with an answer, I would greatly appreciate it.
    Thank you
    Kay

    1. Oliver

      Local authorities have the responsibility for street naming and numbering. They generally pass the information to us and to Royal Mail. Hope that helps.

  7. Claire

    Hi,

    I’ve just bought Explorer 348 for the Campsie Fells. I’ve just noticed though that it’s dated 2007. Are there any plans to update this map, or is it still accurate?

    Thanks,
    Claire

    1. Gemma

      Hi Claire
      That’s still the current version. It’s due for revision early next year and should be released around April 2013.
      Thanks, Gemma

  8. Gemma

    Apologies for the delay John, we missed your first comment. We’re not planning on revising it this year (2012-13) and we are yet to confirm our revision schedule for next year (2013-14). So we have no revision date for 245 planned at this point in time.
    Thanks, Gemma

      OS 245 National Forest
      Any update on when the 2008 printing will be revised, particularly with the opening of the National Forest Way?

      1. Jonathan

        The next revision for the printed paper version of Explorer 245 is due in September 2015. Our Custom Made maps always show the most recent additions our cartographers have added, which is a good option if you need a revised map sooner.

        1. Matthew Harpin

          Jonathan/Gemma,

          Is the revision date for map 245 still correct (September 2015). If that is still the date for the new version, I will hold off a few months before buying one. Please can you confirm?

          Thank you

          Matthew

  9. I purchased OS map 235 as I have just started moving to the area and not only like to walk but to know the area. Our home is 8 years old and not onthe map? do I go back to the supplier or is this normal. The land registry quotes OS, so why are we not on the map.

    1. Melanie

      Hi Peter, If you can let us have address details, we will look into it. The most recent version of OS Explorer Map 235 (Wisbech and Peterborough North) was last revised in 2011 (it tells you this in the legend). I’d suggest you email customerservices@ordnancesurvey.co.uk (rather than do it publicly on the blog) and they will look into the specifics. Hope you are enjoying the new area.

  10. Kay L

    Hi,
    Boyfriend bought a property in 2007. OS map national grid reference NO4607, scale 1/2500, dated 1999. According to OS map, the neighbour is 24 Mid Street, but according to electoral roll register he is 6 Cupar Road. According to the same OS map other neighbour is 4 Cupar Road, yet electoral roll register states his address is in Durham Place (next street down). When I contacted Fife Council about this matter they REFUSED to revert the existing street numbering according to the OS map. They also have no supporting documentation to state that these address changes by these neighbours had been approved. Have any amendments with street numbering been made yet by Fife Council to the OS with regard to Mid Street and Durham Place? If so, can you provide dates when the street numbering changes were made please. we would need to order an updated map.

    Thanks
    Kay

    1. Gemma

      Hi Kay
      This blog was around our leisure mapping, the OS Explorer and OS Landranger maps which don’t go into address level of detail. I would suggest that you contact our customer service centre with your query, either on customerservices@ordnancesurvey.co.uk or 08456 050505 to discuss this issue.
      Kind regards

    Hi
    This is a very useful thread.
    But can Ordnance Survey provide a web-site page where revisions to map tiles(1km squares)and status are listed?
    I have paid out quite a lot of money on digital maps that use the OS data. I would like to know when it is worth paying out another £25 to get another Explorer OL15 sheet(my locality!)
    Could we have access to the revision data?

        1. Melanie

          Hi Eric,
          We publish the list of 1:25k Raster tiles and their currency on our website at http://www.ordnancesurvey.co.uk/oswebsite/products/25k-raster/index.html. If you look at the “useful links” on the right-hand side there is a link called “Full dated tile list”, this shows each 10km x 10km tile and the date of last update of all tiles in the country. Sadly, it’s not the 1km list you’d like, but should be fairly easy to work out if tiles you are interested in have been updated.

          Alternatively, you could look at the edition number and date of the map on our mapshop. The page for OL15 and all other sheets has a tab called “Map details” which shows the published date and edition number. If the edition number has one or more dashes after it (underscores on the map legend) then the map has been reprinted with minor change at the date shown rather than is a new edition. So if OL15 moved from its current B4 edition to B4- then there is minimal change. If it moves from B4 to B5 then B5 represents a revised edition.

          However, you mention digital maps. If you have bought through a licensed partner, it may take some time for the updates to come through and you would need to check with them.

          Our new OS MapFinder app for iOS gives you free tile updates when you purchase at 1:25 000 scale or 1:50 000 scale. It might be worth considering that as an option if you are using digital mapping and happen to have an iOS device – an Android version of the app is being developed and we are hoping to launch it in the summer.

          Sorry for such a long reply, but I hope that helps.

  12. GERARD HULL

    Bradford & Huddersfield OS Explorer 1:25 digital map many years out of date strongly suggest no one buy before checking unless you want a historical map!!!

    1. Melanie

      Hi Gerard, This article talks about how we update our products. However, you bought data from one of our partner organisations who use our data to create their own products. If you can let me now what you think is missing / different on the version you bought, I can look into whether it’s current on our paper and digital maps. Our current paper maps for that area were revised in 2010, so I wouldn’t expect them to be much out of date.

  13. Harriet

    I have a map of Bournemouth and Purbeck Series M 726, Edition 3-GSGS, would you be able to provide any information about the date when this map was published? Any advice would be very much appreciated.

    1. Gemma

      Hi Harriet
      As a rough answer to enable us to provide a speedy response, it sounds like it would be early 1980s. In the longer term, I’ll see if I can find more specific information for you.
      Kind regards
      Gemma

  14. Clare

    I live in Guildford and am a frequent user of OS Explorer 145. However I notice that the popular cycle trail the Christmas Pie trail isn’t marked on the map. The map was last updated in 2007. I was wondering if there was an update planned. Perhaps you could publish a list of all planned updates each year which users could look at to decide when to buy a new map.

    1. Gemma

      Hi Clare

      Having checked with our Products team, the Christmas Pie trail is not included on our maps as our current specification only includes cycle routes that are recognised by Sustrans. They maintain a database of national cycle routes and supply Ordnance Survey with this information and we include this data on our paper maps.

      The OS Explorer Map covering Guildford and surrounding area is included in the revision programme but as yet we do not have a publication date. As it stands the Christmas Pie cycle route will not be included in the next revision.

      As the article above says, there is no one size fits all answer to how often a map is updated, it depends on a variety of factors. I have passed your feedback on to the team about the possibility of publishing an update schedule though.

      Thanks, Gemma

  15. Stuart Taylor

    I’m going through some old maps and noticed that around 2004 the edition details changed from things like “3rd edition of the new revision” and “new edition of the 2nd revision” to a simple C2 or D4 coding.

    Is there any easy way to convert the older edition/revision statements into the new alphnumeirc coding?

    Thanks, Stu

    1. Melanie

      Hi Stu,

      The alphabetical changes occur when we totally revise a map – so if sheetlines change or the area covered is changed. The numeric refers to the a revision, so each time an edition is revised it will increase.

      The letter stands for a complete ‘revision’
      The number means the map was ‘revised for selected change’
      And if there are bars under the letters mean it is a ‘reprint with minor change’

      If you want to let me know the specific map series which you are looking at, I will see whether we have any further information.
      Best wishes,
      Melanie

      1. Stuart Taylor

        Hi, thanks for that, makes sense.

        I’m looking at electronic records of Landranger series, trying to see if they represent up to date maps (or at least how out of date they are) and the edition would be useful, but some are listed as the C2 variety, others are listed as 4th Revision, or 3rd edition of the new edition.

        Would it be safe to assume that 4th Revision would equate to a D, 3rd to a C etc?

        Cheers

        1. Gemma

          Hi Stuart

          It’s not quite as simple as that I’m afraid. The amount of change on the map dictates whether a map moves from, for example, A2 to A3 or becomes a B. So you’ll always know that a C is more current than a B2 for example.

          If you have a specific map you’re asking about we’d be happy to look into it for you; we can’t accept attachments via the blog, but you can email a photo or PDF to customeservices@ordnancesurvey.co.uk and it will be picked up.

          Kind regards
          Gemma

  16. David

    If you order a custom map of an area does it use the latest updated tiles or the data from the most recent published map? Thanks

    1. Gemma

      Hi David
      Huge apologies for the delay in responding to this. We were migrating the blog to a new format and all comments were suspended while work was carried out. Our Custom Made maps are created from the latest updated tiles. The tiles used to create Custom Made are refreshed every three months (which means any updates are captured and uploaded every three months, not that all tiles are updated every three months.)
      Many thanks
      Gemma

    Hi,

    I am using the OS Map 275 of Liverpool (st helens, widnes and runcorn). I was wondering when this map will be updated, as the newest one for this area is from 2002?

    Thanks,
    Kyle

    1. Hi Kyle

      I’ve checked with our Products team and I can inform you that the OS Explorer Map 275 sheet has been revised in 2004 and 2008 and the latest is 2011.

      Many thanks
      Gemma

  18. Chris Hyams

    Hello, have noticed that the small village of Lower Compton (just east of Calne, Wiltshire) is not indicated on the ‘Swindon & Devizes 1:50,000 Landranger’ map. There are village signs on each side of the village and directional signs from the A4, so it is a valid location. It is distinct from Compton Bassett, approximately 2 km miles to its northeast.

    Also not indicated is the large hamlet of Pewsham, approx. 3 km west of Chippenham on the A4. Again, this is well signposted in the area and has its own village entrance signs on each side. Pewsham was also (confusingly) the name given to a new housing development in east Chippenham in the late 1980s, which is now indicated on the Landranger map.

    Is there a reason why OS chooses not to cite these places on this map ?

    With regards, Chris Hyams

    1. Hi Chris

      Thanks for the question. I’ve passed this along to our Customer Services team to look into and they’ll get back to you as soon as they can.

      Thanks, Gemma

  19. Gary Kinch

    I’ve been researching a river/stream in Hastings (1066 and all that). On the map it’s called the “Combe Haven” however many locals call it the Asten. Having looked into it, all historical books/documents call it the Asten. The source of the Asten features in many accounts of the battle of Hastings. Asten is considered a corruption of the word Hasta from which the name Hastings is derived. The change in name to the “Combe Haven” seems to have occurred around 1850-1900 and appears to be the result of an error. The valley through which the river flows is called the Combe Haven Valley but the river was called the Aston for many centuries…….Given the historical significance of the name Asten is there any likelihood of future maps being corrected?

    Regards.

    1. Hi Gary

      Thanks for the query, that sounds like some interesting research into the area. At Ordnance Survey we record the features on the ground and we’re not responsible for naming (or renaming) the features themselves, they’re taken from local signage and information passed to us by local authorities. I think your best course of action would be to contact the relevant local authority to discuss this with them and if any renaming decision was then taken, the information would then be passed to us by them for inclusion on our future maps.

      Kind regards
      Gemma

  20. Gary Kinch

    Sincere thanks for the swift reply Gemma. Your answer makes perfect sense and it points me nicely in the right direction.

    Regards,
    Gary.

  21. Steve

    Hi, significant changes have taken place on the Thames estuary at Stanford le Hope/Coryton, Essex, with the creation of the London Gateway Port (started in 2010 and opened in Nov 2013). These changes include a 2.7km long by 400m wide reclamation to create the Port. Can you advise when this and other changes nearby will be added to the OS maps?
    Regards,
    Steve

    1. Hi Steve

      I’ve just been checking this with our Products team and they tell me that we have registered the area you mention as a prestige site development. This means that it is a high priority to be included on our mapping as and when changes take place. A wide range of our digital products have been revised regularly, but most recently within the last two months, including OS VectorMap Local, 1:25 000 Scale Colour Raster and 1:50 000 Scale Colour Raster.

      Being a prestige site our commitment is to keep a watching brief on development in that area and as soon as surveyed change is captured it is given priority to be included in our products. The exception may be the paper maps (OS Explorer Map and OS Landranger Map) where this process may take longer for the updated sheets to find their way into the supply chain. This also applies to our zoom-stack products (such as the maps used in OS getamap) but we are looking to updating them more frequently than their current schedules. I don’t have a specific date to share with you right now on the revision of the paper map, but will pass that on to once I hear.

      Many thanks
      Gemma

  22. Emilio Casalicchio

    I have an OS map of the Brecon Beacons from the 70’s. I’ll just be doing some fairly light walks there, maybe up to 10 miles or so in a day at the most and always back to a base campsite (rather than accross a whole area).

    Will my old map be OK for this? Or will there have been changes to the region and therefore maps that will make my using it dangerous or idiotic?

  23. Jon Mason

    Hi – can you tell me when the paper Explorer maps #258 and #259 will be updated? The current ones both date back to 2008. Many thanks. J

    1. Hi Jon

      I’ve just checked with the product manager and there are minor changes to these maps and he’s expecting both of them to be reprinted before the end of the year. To be sure it’s the new version, do check the edition number inside the map on the legend, in both cases this will A1__ (double underscore). The cover will look the same.

      Many thanks
      Gemma

  24. Christine Holgate

    Hello

    I am trying to find out if a paper copy should exist of the large scale 1:2500 map of Copt Hewick SE3471SW for 1993. How often were village areas revised at that time, and at what date were maps of that scale completely digitised?

    Kind regards
    Christine

    1. Hi Christine

      Thanks for your message. I’m afraid Ordnance Survey has not held any historical maps since 2008. The majority of maps which were held by Ordnance Survey were distributed between various sites around the country. You may be able to view various other historical maps free of charge at local libraries. A small charge may be made for a copy if required. Licensing terms and conditions apply to mapping still in copyright (mapping produced within the last 50 years). Legal Deposit Libraries, such as The British Library, Bodleian and Cambridge University Library hold more extensive collections and offer reading and copying facilities for customers willing to visit and carry out their own searches.

      Large scale digital mapping has been available to customers since the late 1990s but much of that mapping may have been digitised from older mapping. New technologies enable us to react to change much faster now and change is captured on a continuous basis and frequency change is determined by how much development is taking place and how important the changes are. For example for a new housing development we aim to survey the area and update our mapping within six months. Please note that frequency of change will not always correspond with publication of a map as much of our mapping is held as digital data for supply on demand. Further information regarding our Revision policy is available from our website: http://www.ordnancesurvey.co.uk/about/governance/policies/basic-scale-revision.html

      Landmark’s ‘old maps’ website is a useful resource for finding out what maps are available for different periods: http://www.old-maps.co.uk
      However we do still sell a limited reproduction range of 1 inch to 1 mile maps (revised from the late 1800s and published in the early years of the 1900s) from our Leisure Map Shop as well as various historical products produced by our Licensed Partners:

      I hope that information is helpful, but should you require more information, our customer services team will be best placed to help. They’re available on 03456 050505 or customerservices@ordnancesurvey.co.uk

      Many thanks

    My farmhouse is incorrectly identified with the name of a neighbouring farm. I am concerned as, if the need should ever arise, the emergency services may not be able to locate us. How do I provide you with the required details to get the mapping corrected?

    1. Hi Malcolm

      Thanks for your query. If you’re referring to the name placement on our paper map products, due to scale, the cartography team place names as close as they can without obscuring other features. The emergency services have access to our most detailed digital data products and use those to locate addresses, AddressBase contains over 38 million individual addresses across Great Britain. Those datasets contain much more detail and intelligent data than our paper map products, which are designed for walkers, cyclists and so on. You can read more about our work with the emergency services here: https://www.ordnancesurvey.co.uk/business-and-government/public-sector/emergency-services/index.html

      If you’d like to have your paper map query looked into however, you can contact customerservices@ordnancesurvey.co.uk

      Many thanks

    Thank you Gemma – I will send the details to your customer services group. Your quick response is appreciated to my query.

    I am wanting to replace some of my old and scruffier Landranger maps with recent editions. I can see the revision dates on your web site. Can you let me know if Landrangers 44, 58 and 59 are expected to be revised soon as the revision dates shown are all at least 5 years ago.

    1. Hi Sarah

      Thanks for getting in touch – if you’ve been following our OS Photofit competition, you’ll know that we’re rebranding all of our paper map range over the next 12 months, with the Landranger series and their new covers rolling out in 2016. As a result of that there are no planned changes this year. I should point out though, that while 44 and 59 were last updated in 2010, 58 was updated in 2014.

      Many thanks
      Gemma

    Hello,
    When is Landranger map # 183 likely to be updated ? It seems it was last updated a full decade ago ! Is this correct ?
    With regards, Chris

    1. Hi

      I’ve checked with our Cartography team and they tell me that 10-GSGS, is an edition note added to military mapping, 10 is the edition and GSGS means Geographical Section of the General Staff. To answer how old it is and what is the latest edition, then we would need to know what mapping it’s on.

      Thanks, Gemma

    Hi

    Can you tell me what years the os map 203 of lands end were published or revised from the 1985 one to the present day. I think ive found a new one was brought out in 1992 but were there any more between 85 and now? Thanks

  30. Peter Fletcher

    Hi, I use a lot of land ranger maps for historic rallying , am I correct in thinking that an undershot on the map edition is a very minor change and a major revision reflects in the letter but how does the number after the letter reflect in a change.
    Many thanks Peter

    1. Hi Peter

      I’ve just checked with our Customer Services team on this one. They’ve advised that the edition letter/number system was roughly as you describe. In full:
      Change of letter = full revision of the sheet, “Revised for significant change”
      Change of number = changes to major features (e.g. new roads, developments, settlements) “Revised for selected change”
      Addition of underscore = changes to minor features, “Revised for minor change”
      As you may be aware, this system is now no longer in use since our recent rebranding, with editions instead being marked by year and month. So the new batches of the Explorer series released last year have were edition “2015-05” or “2015-09”, and the new Landranger titles coming out next month will be “2016-02”.

      Many thanks
      Gemma

    Hi Team

    Any idea when the Explorer 252 (Norfolk Coast East) is to be updated? I planted and named a new wood 12 years ago and although only one hectare is a pretty significant feature – and a planned location for holidaying – I also want to buy one of your customised maps with this area centralised but currently just shows as a field rather than a wood. Many thanks.

    1. Hi Steve

      Our Customer Services team will be able to look into this for you, but will need a bit more information. Could you let us know the location of the wood and some information on the naming, such as whether you informed us of the name or it came from a local authority etc. Happy for you to post the information here and I’ll pass it along to the team, or you can email them direct on customerservices@os.uk

      Thanks, Gemma

      1. steve williams

        Hi Gemma – thanks for your reply – yes of course you will need more info, I will try and sort it. We have named it ourselves for identification purposes but is there a procedure for this is it is to be mapped officially?

        Incidentally, I did notice a mistake on my Broads map OL 40 explorer. Just a minor one but on the Bridge Clearances key – the Novi Sad metric clearance should be 3.05m.

        Many thanks

    Hi, please can you confirm when it is proposed to update the 1:50,000 digital mapping to unclude the Heysham Link (new road infrastructure near Lancaster)?

    1. Hi Wayne

      The new road is surveyed and in our database and already included in our OS MasterMap Topography Layer and 1:50 000 Scale Raster data. It will take a while to filter through into other products, including the digital OS Maps overview layers, all depending on their update schedules.

      Many thanks

    Hi OS Team,

    A quick question. My mother and I have recently planted a copse of around 60 trees and 100 shrubs in the field behind our house and I was wonder if it would be possible to have it entered on the OS map?

    Looking at other local features it appears to be of sufficient size to be noted on the map.

    Thanks,

    James

    1. Hi James

      This is quite a tricky to answer without some more information. For example, if this area is private garden we would not put it on the mapping. If it’s not a private garden, the trees would need to be established before we would add them to our mapping, so it is possible that the area would be added to our mapping in the future. If you do have any further information, send it over to our Customer Services team at customerservices@os.uk and they can investigate.

      Many thanks
      Gemma
