Elevation Data

We use two sources for elevation data: aerial imagery and LiDAR. While LiDAR-derived models offer higher vertical positional accuracy, imagery-derived models are a cost-effective alternative typically with higher point densities, better canopy modelling, as well as increased building material identification and classification accuracy.

Imagery-derived elevation data is available wherever standard orthophotos are offered, including North America and Europe. LiDAR-derived elevation data is only provided in urban areas through our Metro HD city program.
