Height Data - NEXTMap
NEXTMap® Britain provides customers with highly accurate Digital Elevation Models which model the ground surface in great detail.
- An elevation point provided every five metres and a vertical accuracy of one metre
- Selected more densely populated areas are available with a vertical accuracy of 50 centimetres
- A digital orthorectified radar image (ORI) data set is also available providing a highly detailed grey scale image of the earth’s surface
- Available as a DSM, DTM and Contours at 5m or 10m postings
Usage
- The NEXTMap® Britain datasets are an invaluable working resource for a wide range of professionals from engineers and environmentalists to land use specialists, government agencies and many more
- The DSM is perfect for applications such as radio signal propagation analysis, noise and wind modelling or to create 3D landscapes in combination with aerial photography
- The DTM also known as a “Bald Earth” model, removes trees and vegetation, buildings and other man-made structures to expose the underlying terrain
