We’ve now completed the digitisation of Wiltshire’s tithe maps: ICAM, the firm undertaking the work, have photographed over 300 maps. The tithe maps will be joined on the Know Your Place website by Ordnance Survey 25” mapping for the county, supplied by the British Library. The OS mapping includes town plans for Bradford-on-Avon, Chippenham, Devizes, Salisbury, Swindon, Trowbridge and Warminster.
However, before the images can be uploaded onto the website, we need to do some preparatory work with them. And this is where you can get involved in the Know Your Place project.
This autumn we will be recruiting volunteers to undertake georeferencing work. Sounds interesting you say, but what is georeferencing? Put simply it is the process of assigning geographical coordinates to a map image; linking the historical information to its modern spatial location. This means the image is ‘spatially enabled’ – using geospatial tools it can be searched, interrogated and visualised alongside other maps images. If you’ve ever used mapping websites such as Googlemaps and moved around an area, zoomed in and out and toggled between a map layer and a satellite photo layer then you’ve used a geospatial tool and spatially enabled data.
Still sounds a bit technical? Don’t worry, we will be running a series of training sessions at various locations across the county towards the end of the year. Once trained, you can work on your own computer at home using free, open-source software. In the training we’ll show you how to download, set up and use the software and how to transfer the work to us once you’re finished.
If you love maps, want to look at change and continuity in a particular area in more detail, if you’re interested in developing your IT skills or would just like to contribute to Know Your Place then this is a volunteering opportunity not to be missed. Keep an eye on our Twitter feed and Facebook group for updates on volunteering training dates and to follow our progress.
