The NEXTMap topographic data was collected using Intermap’s Star-3i IFSAR (Interferometric Synthetic Aperture Radar) producing a Digital Surface Model (DSM), a Digital Terrain Model (DTM) and orthorectified radar imagery (ORI) for the whole of the England, Scotland and Wales. All data has been processed to the OSGB National Grid and Newlyn Datum.

BUILDINGS
Geosense has devised semi-automatic routines to enhance the NEXTMap Britain product by using photogrammetrically derived heights of buildings from Getmapping stereo aerial photography. The building models are accurate up to 50cm and are either embedded into the NEXTMap terrain models or as 3D outlines to be placed on top. Formats include 3D shapefiles and dxf. Buildings shown here are flat-roofed, ideal for telecommunications - mast site planning and line of site, noise pollution monitoring and visual impact assessment.
