RadarMap (NEXTMap Britain)
RadarMap is derived from the InterMap NEXTMap Britain dataset, covering Great Britain (not including the Isle of Man). It consists of highly accurate, up-to-date, terrain grid data at a range of resolutions, depending on your application.
RadarMap suggested applications
- Zones of visual intrusion;
- Insurance risk;
- Wind farm planning;
- Line-of-site analysis.
RadarMap features & use
- Two flavours available – Digital Terrain Model (DTM) and Digital Surface Model (DSM);
- Grid available at 10m or 5m intervals with height accuracy of ±1m root mean square error (RMSE) in areas of minimal vegetation and terrain slope less than 20 degrees;
- Visualise the ground surface as a coloured two-dimensional map view;
- Drape other map layers onto 3D view of the land surface;
- Construct models to simulate drainage and probability of flooding;
- Suitable for large-scale mapping at street-level – for example, with contextual PlannerMap product derived from Ordnance Survey OS Street View Raster dataset;
- Available as full national GB coverage or smaller ‘cut-out’ extracts (priced per sq km).
RadarMap technical information
The grid data set is in individual 10km square tiles, with a seamless table (for use in MapInfo Professional GIS) to present them as a single layer.
Suitable for scales on screen in the range 1:100,000 to 1:10,000.
The British National Grid co-ordinate system is used.
The storage space required is approximately 26Mb per 10km square tile for DSM at 10m in MapInfo TAB format.
Main formats available: MapInfo TAB, ESRI SHP, AutoCAD DXF, Illustrator EPS and others.
