New Digital Maps available on Reading Room Terminal
As the maps reading room is now open again to readers, we’d like to point you in the direction of the digital maps viewer. Before you read on please note that the viewer is only available on-site in the maps reading room, you must book a space in advance of your visit by following the instructions here.
The digital maps viewer allows readers to browse maps and geospatial data that the library has collected over the last twenty years using a ‘slippy’ maps interface similar to Google, Bing or Apple maps. Snapshots of Ordnance Survey Great Britain Master Map and Ordnance Survey Northern Ireland Large Scale mapping are added every year and the 2020 versions are now accessible to readers in the viewer alongside older versions.
Whilst the library has been closed we have been busy gathering new data and we’re happy to announce that 36 new environmental and heritage datasets are now available to view. These include British Geological Survey open datasets and heritage datasets from Historic England, Historic Environment Scotland, Northern Ireland Department for Communities, the Royal Commission for the Ancient and Historical Monuments of Wales and CADW.
Furthermore 523 charts of the Western Isles of Scotland published by Antares (http://www.antarescharts.com) are also now accessible. These beautiful, very large scale charts and related pilotage information are created by yachtsmen. Antares tell us that:
‘All our charts have been compiled from our own surveys. Surveys are made by criss-crossing an area in an inflatable boat equipped with an accurate gps (+/- 2m), depth sounder and data logger. Soundings are fed into surveying software, reduced to chart datum by deducting the height of the tide and then plotted to make the chart.’
For more information on the fascinating process used of creating the charts please see http://www.antarescharts.co.uk/index_files/Making_the_charts.htm
Please note that a booking is required to use the viewer. To book speak to reading room staff on arrival in the maps reading room. Do please be aware that at busy times there may be a wait or you could be asked to come back on another day.
