I’ve talked in previous posts about the new head office we’ll be moving to later this year and how excited I am about a shiny new building – but what about all that packing? If you think that there are around 1,100 of us currently living in a building intended for around 3,500–4,000, you can imagine how much space we’ve got. And if you think about what you do with any spare space in your home (come on, I bet your lofts, garages, sheds and cupboards are packed to bursting!), then you can imagine the task facing us after 40 plus years at Romsey Road.
Paul’s already updated us on the historic artifacts we’ve uncovered, but there are also thousands and thousands of old maps and map-related records. So, what do we do with them? There are actually several routes we follow. Our Historic Map Archive has been used to complete collections and libraries up and down the country for example.
We recently caught up with two of our Inverness surveyors to find out what challenges they face in their remote corner of Scotland. They mentioned mapping the changes at a hydro scheme and I thought it might be an idea to find out how we updated our OS MasterMap database to show the Glendoe Hydro Scheme, Scotland’s largest recent civil engineering project. Craig and Dave faced a technical challenge in finding the best way to map the new and changed topographical features.
The Glendoe Hydro Scheme is located in the hills above Loch Ness near Fort Augustus and although a significant part of the project is underground, many new and changed features needed to be incorporated into our OS MasterMap database. These included the dam wall, the reservoir, all of the access and service roads, changes to water courses and their associated walls and sluices, and changes to the extents of vegetation and other surface features.
The job of a surveyor is the one that we get asked about the most. People are fascinated by the people in hi-vis jackets that work their way around the country capturing the 5 000 changes made to our database everyday. Craig Methven and Dave Robertson work in our Inverness field office and told me what they get up to…
You might have read my blog on Wessex Archaeology’s finds at our new head office, describing the Bronze Age Farm that was once on our Southampton site…while chatting with the team, based on the outskirts of Salisbury, I discovered just how much they rely on our data, both on paper and in numerous electronic formats. Talking to Paul Cripps, Geomatics Manager at Wessex Archaeology (WA), I discover that their mapping interests run from historic mapping to OS OpenData and a whole range in between.
Much of WA’s work is spatial, finding out how things relate to each other. From historic buildings to excavations to the marine environment, mapping is fundamental to everything WA do. But they don’t just use it as a backdrop, they add information about their excavations and finds too and attach that to their mapping. I was surprised to find that the historic mapping is not only needed to understand change through time but to ensure the accurate interpretation of aerial photography amongst other things; it is not always easy to work out what is shown in an aerial photograph alone and the feature may not be shown on more modern maps, a second world war bunker on a disused airfield can look very similar to a Roman fort from the air!
I met up with Wessex Archaeology recently to find out about the previous residents at Adanac Park, the site of our new head office.
Back in 2008, as part of the planning process, Wessex Archaeology were asked to investigate the site for historical interest. They were fairly confident of finding some archaeological remains as there had been finds at sites in the local area, but were surprised to find evidence of a late Bronze Age farm, the first of its kind in this part of Hampshire.
Archaeologist Andrew Fitzpatrick told me, ‘The site proved to be late Bronze Age, around 3,000 years old, four or five houses and evidence of smaller structures, such as storage sheds and granaries. There was also an Iron Age burial ground with seven barrows and other graves. This was quite unexpected and the site is unique in Britain.’
