  3. From GDEM V3 (Global Digital Elevation Model V003) dataset I have sampled at a resolution of 13 million per degree latitude and degree longitude. In everyday terms the town of Andover, Hampshire is sampled approximately 45 thousand times. From my testing this is enough to pickup subtle changes in road elevation over small distances, such as a couple of house blocks. ↩︎
