Return to this page by reselecting the icon or pressing [Esc] on your keyboard.<br \/>\n&nbsp; Search for a specific location.<\/p>\n<p>The underlying hillshade map layer is largely derived from high resolution (typically, 1m) <a href=\"http:\/\/environment.data.gov.uk\/ds\/survey\/index.jsp#\/survey\" target=\"_blank\" rel=\"noopener noreferrer\">LiDAR Digital Terrain Model (DTM)<\/a> from the UK Environment Agency. This provides around 2\/3 coverage of Dorset, and is more extensive for coastal and low-lying areas. Full coverage should be available in the next few years. The remaining hillshadeis derived from lower resolution (25m) data from the <a href=\"https:\/\/www.eea.europa.eu\/data-and-maps\/data\/copernicus-land-monitoring-service-eu-dem\" target=\"_blank\" rel=\"noopener noreferrer\">Copernicus Digital Elevation Model over Europe<\/a> (EU-DEM) and the Ordnance Survey DTM5 (5m resolution). The Hillshade map tiles have been generated using QGIS<\/p>\n<p>The hillshade accentuates the landscape and geomorphology; including coastal erosion features, quarries and archaeological features such as hill forts, round barrows, and strip lynchets.<\/p>\n<p>The geology layers are provided by British Geological Survey (BGS) <a href=\"https:\/\/www.bgs.ac.uk\/data\/services\/wms.html\" target=\"_blank\" rel=\"noopener noreferrer\">Web Map Services<\/a> (WMS). As you zoom in, the geology layers switch from&nbsp; a 1:625 000 (DiGMapGB-625) overview to the more detailed 1:50 000 (DiGMapGB-50) scale. If you click on the maps, relevant geological details (Group, Formation, Member, Bed etc) are displayed.<\/p>\n<p>Similarly, as you zoom in, Ordnance Survey 1:50 000 (Landranger) and 1:25 000 (Explorer) map layers are progressively displayed, via <a href=\"https:\/\/www.bing.com\/maps\" target=\"_blank\" rel=\"noopener noreferrer\">Bing Maps<\/a><\/p>\n<p>From the layers menu (top-left), detailed historic Ordnance Survey maps of Dorset and adjacent counties may be displayed. These are reproduced, for educational, non-commercial use, with the permission of the <a href=\"https:\/\/maps.nls.uk\" target=\"_blank\" rel=\"noopener noreferrer\">National Library of Scotland<\/a><\/p>\n<p>Details of other map layer providers can be found in the Data attribution link at the bottom of the terrain map.<\/p>\n<p>Location coordinates are displayed by hovering your mouse-pinter over a position. These are given as decimal Longitude\/Latitude and as British National Grid Reference. The accuracy should be around 2m, comparable to that of the map layers and consumer GPS devices.<\/p>\n<p>As an alternative, you can also view 2D geological maps in the BGS <a href=\"http:\/\/mapapps.bgs.ac.uk\/geologyofbritain\/home.html\" target=\"_blank\" rel=\"noopener noreferrer\">Geology of Britain<\/a> viewer.<\/p>\n<p>Older versions of geological maps and sections may be freely viewed via the <a href=\"https:\/\/www.bgs.ac.uk\/data\/maps\/home.html\" target=\"_blank\" rel=\"noopener noreferrer\">BGS maps portal<\/a><\/p>\n<p>There is also a BGS <a href=\"http:\/\/mapapps.bgs.ac.uk\/geologyofbritain3d\/index.html\" target=\"_blank\" rel=\"noopener noreferrer\">Geology of Britain 3D<\/a> (Beta version) viewer.
