Elevation Data

Take your project to new heights

High-accuracy elevation data for 3D visualisation and spatial analysis.

Water sustainability efforts in Southern California aided by Hexagon's aerial data

Rancho California Water District raises its landcover classification accuracy above 96% with help from the Content Program and DCSE, a Hexagon resale partner

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.

Digital surface model elevation data of Berlin Airport

Leverage digital surface models (DSM) to extract elevation data of built-up and natural features. We offer countrywide photogrammetric DSM of North America and Europe at multiple resolutions and point densities. Photogrammetry-derived elevation values represent the highest elevation for each pixel, while LiDAR-derived DSMs are generated using first return point data.

Digital elevation model of industrial facility in Tokyo

Digital elevation models (DEM) provide direct and interpolated heights of the earth's topographic surface devoid of all above-ground features such as buildings and vegetation. LiDAR-derived DEMs are produced using classified ground data returns, while photogrammetric DEM relies upon automated grid interpolation to remove surface features in the data.

LiDAR point cloud elevation data of skyscrapers in Tokyo

A multifunctional data set that enables 3D modelling, LiDAR point clouds provide high-accuracy spatial data of physical objects and terrain using a collection of dense point measurements. Our point clouds are encoded with spectral information from corresponding aerial imagery and include intensity, return number and scan angle as attributes.
