Digital Surface Models (DSM)
Off-The-Shelf Elevation Models for a Complete 3D View
Hexagon’s HxGN Content Program offers nationwide digital surface models (DSM) up to 20 cm resolution (nominal point spacing) across the United States and Europe. The data is orthorectified, standardized and homogeneous, making it ideal for extracting features and deriving analytics.
Description
The HxGN Content Program, Hexagon’s aerial data program, offers the largest library of high-resolution multispectral aerial imagery and elevation data of the United States, Europe, and parts of Canada. Hexagon is the only aerial data provider to offer off-the-shelf nationwide DSM at 80 cm resolution across the United States and Europe.
Derived from quality controlled, high-accuracy aerial imagery, the HxGN Content Program’s DSM provides a clear view of the surface and its above-ground features in a 3D format. It is readily available and can be used for landscape modelling, city modelling, visualization applications, flood modelling, land-use studies, and geological applications. Unprecedented consistency and positional accuracy makes it an ideal data source for automatic feature extraction and machine learning applications. Flexible data use terms allow users to create derived products.
