TERRAIN & HEIGHT DATA

Bluesky Digital Elevation Models data facilitates the understanding, analysis and management of the environment that surrounds us. Whether you’re interested in the terrain (DTM), or surface features such as buildings and trees (DSM), our data provides detailed height measurements at high accuracy and resolution.

The data is derived photogrammetrically from aerial photo and depicts the surface of the earth with a very high degree of accuracy.  This type of data has a wide range of applications, and provides an alternative to LiDAR.
