100 metre TOPOGRAPHY
Terrain maps at a pixel size of 100 metres can be produced to order for any location between 60 degrees North and South, based on the most detailed publicly-available digital terrain data (SRTM3). Click here for more information about our improvements to this spaceborne radar-derived source data.
