Thanks to the new Ordnance Survey Data Hub, it’s easier than ever for users to get their hands on the treasure trove of geographic data covering the length and breadth of Britain. In this article, I’ll explain how I used some of Ordnance Survey’s digital terrain model data to create a new map of the Scottish Highlands. I will also say a bit about the software and methods, and I’ve shared the data below so anyone who is interested can try it for themselves. But before that, let’s take a look back at the first ‘3D map’ of the Highlands.
The first ‘3D map’ of the Highlands
Guest blog by Simon Pattullo, Product Owner at Scottish Environment Protection Agency
If you haven’t heard of the Scottish Environment Protection Agency (SEPA), we are Scotland’s principal environmental regulator tasked with protecting and improving Scotland’s environment.
One key tool we use is Permitting and as such, our service needs to be efficient, so we’re constantly working to improve it. We have always been largely paper based, but this is changing. The progress we have made so far within our Permitting department has even won us an award. Read on to find out more…
The Understanding Scottish Places (USP) platform launched in April 2015, offering a way of understanding the similarity of places across Scotland. The tool contains a range of demographic, social and economic data on all 479 Scottish settlements with a population of over 1,000 people. Deliberately designed to avoid a simplistic ranking of places as better or worse, USP focuses on the shared characteristics of towns.
When you’re out in the countryside, particularly if you’re camping, it’s impossible to avoid midges and mosquitoes. These types of insect are an important part of our ecosystem, and there are trillions of them, but you may be tempted to forget this when you’re under attack.
The best you can do is to employ some kind of skin protection, stay away from the type of habitat and conditions that midges like, and know how to deal with bites you might get. Learning a bit about why midges bite, and what attracts them can also help you plan your avoidance strategy.
We currently have 250 field surveyors who contribute to the 10,000 changes taking place every day in our database. Thanks to them our master map of Great Britain is constantly, subtly shifting and changing. Luckily, the country is nothing if not varied, and not all of our surveyors are pounding concrete and worrying about urban canyons (the phenomena of being in an area so built up that satellite signals – can’t reach their GNSS kit). Some spend their days surrounded by sheep, not Starbucks. One such surveyor is Guy Rodger who looks after Shetland. Guy’s worked for OS for 30 years and spends an average of four weeks in Shetland every year and has to carefully plan his work to maximise his time there. I caught up with him recently to ask him some questions.
We make 10,000 changes to our geospatial database every day in order to keep it as up to date as possible. We have a team of 250 surveyors who collect change across the country as well as two aircraft which collect highly detailed aerial imagery which is incorporated in to the database.
Many of the changes are small; changes to road layout and pavements or changes to individual buildings and new developments, but from time to time we need to survey something a little more unusual in order to make sure that we record everything you can see in the landscape.
The Cuillin Mountains of Skye in the Highlands of Scotland are renowned as having the most challenging mountain environment anywhere in Britain. These mountains contain narrow, complicated ridges where a day’s outing can require a mountaineer’s skill and knowledge to overcome their difficulties.

Following on from the success of Britain’s new mountain back in April this year, we have a guest post from Myrddyn Phillips on his next mountainous challenge.
Balanced precariously on the aptly named Pinnacle Ridge in the Cuillin Mountains of Skye in the Highlands of Scotland is a lump of rock that may well prove to offer the most difficult mountain survey ever conducted in Britain.
The mountain in question is Knight’s Peak (grid reference NG 471 254). Its summit is situated amongst castellated peaks in the most challenging and dramatic mountain range Britain has to offer.
The summit of Knight’s Peak consists of two tops a short distance apart. One top is spacious enough for one person to balance on its highest point, whilst the other is a pointed top where standing is not advised. The land beyond the summit area is precipitous.
We do like to find unusual examples of maps and we loved this idea for a range of map-based jewellery. Today’s post is by Glasgow-based jewellery designer and silversmith, Clare Spencer, who uses our OS OpenData to create her map-based jewellery range, Lie of the Land.
Since moving to Scotland six years ago, I’ve been continually charmed by its natural landscape and have been looking for ways to celebrate it in my work. The first opportunity presented itself when I was asked to make a personalised pair of earrings for a client’s mother. The only stipulation was that they had a connection to Tain, her birthplace, situated on the Dornoch Firth. Looking at maps of this area, I noticed that the lines of the land and the sea had a natural rhythm. The result is a pair of earrings that together make up a section of that coastline. Tain is marked with a tiny turquoise gemstone. The recipient was delighted with such a personal gift and sent me a lovely thank you card.
Studying Ordnance Survey maps, I was intrigued by the shapes of different lochs (of which there are over 31,000 in Scotland!) and saw how their shape would work well as cuffs and rings making special gifts for those with an affinity to a particular place.
It was important to me that the outlines of my jewellery were accurate and that I was able to access maps for which I had copyright permission. A search on the Ordnance Survey website revealed their open source data [OS OpenData]and a phone call to a helpful, knowledgeable staff member confirmed that I would be able to use the data for free as long as I acknowledged its source. This information is now printed on my business cards.
Clients might commission map-based jewellery for a variety of reasons – as a gift for a lover of Scotland’s outdoors, because of a childhood connection to a place, in memory of a special holiday, as a wedding gift (incorporating the location of the ceremony) or as corporate gifts for international clients.
As well as lochs, islands have formed the basis of my requested commissions. The Isle of Skye has been very popular and I’ve been asked to make pendants, brooches and cuff links in its shape.
As a content editor based in Southampton, it’s easy to miss what’s going on in Scotland, home of the One Scotland Mapping Agreement (or OSMA.) Having recently updated the web pages for the OSMA team, I thought a round-up of news from north of the border was now due.
We recently released a new product that has some relevance to the recent ‘rainy season’ experienced in 2012. According to this Met Office article, as you may have suspected, 2012 was one of the wettest years on record, so the launch of the new OS MasterMap® Networks – Water Layer alpha release seems like an appropriate choice for understanding our changing environment in greater detail.
The thinking behind this new product came from the Scottish Detailed River Network (SDRN) project: a collaboration between Scottish Government, Scottish Environment Protection Agency, Scottish Water, local government in Scotland, and Ordnance Survey, tasked with delivering a highly detailed river network dataset in support of the Flood Risk Management (Scotland) Act 2009.
An alpha version of OS MasterMap Networks – Water Layer dataset (covering Scotland), was released by Ordnance Survey in December 2012 and is exclusive to public sector organisations in Scotland who are members of the OSMA.
What is the OS MasterMap Networks – Water Layer?
The new layer in OS MasterMap is designed for public sector organisations who are working on the challenges that our current climate brings to many communities. So, if you are a local authority looking at flood defence planning or you work for a central government organisation looking at disaster planning, this could be a product that will add real value to your digital geographic resources.
The water layer can help you plan work efficiently by providing details on rivers, watercourses, width and direction of flow, without you having to leave the office or get wet. This could be used to map your organisations assets, plan any construction, or review flood-prone areas against a digital backdrop of highly accurate geographic information.
3D fire incident maps
In contrast to the activity around water, fire services in Scotland are also benefitting from using digital map products provided through the OSMA.
Centralisation and using digital tools to improve efficiency is an ever present in many areas of the public sector. From 1 April 2013 there has been a single Scottish Fire and Rescue Service (SFRS), and a strategic team has been appointed by Alasdair Hay, the Chief Fire Officer for the new service. Going forward, the SFRS will consist of three hubs, for East, West and North Scotland, taking a centralised approach to providing this particular emergency service.
The existing eight Fire and Rescue services in Scotland are all members of the OSMA and many have already used the products available to them through OSMA, helping them to improve the services they deliver through the use of geographic information in a digital format.
One notable example of this is from the former Strathclyde Fire and Rescue Service (now a part of the SFRS) who have made use of digital maps, addressing and building height data to support their incident response plans.
OS MasterMap Topography layer provides the basis for building a quite sophisticated incident map, Details on the structural environment provides the intelligence needed for those who will be deployed to the location on the ground. OS MasterMap Topography layer provides an easy, time-saving way to create the detailed 3-D models that clarifies and helps with the management of any significant risks.
OS MasterMap Topography layer includes more than 400 million individual features, including railways and individual buildings, providing a detailed view of the urban landscape which is ideal for this work.
The image (above) gives an idea of how this information can be viewed in a 3D format, making the most of geographic and location information, to provide detailed insight and intelligence to the control room.
Scotland is clearly a place to watch in terms of the innovative use of map data in the public sector. I hope to be bringing you more examples of using geographic information to drive improvements in the public sector from this part of the world very soon.
