3D Surface Model: The 3D Surface model provides one of the most accurate representations of Earth, featuring 50 cm resolution with authentic textures and 3-meter absolute accuracy across all dimensions. This exceptional precision is maintained consistently across all terrain types and surfaces—including building facades—without requiring ground control points.
Digital Surface Model (DSM):
The DSM is a product derived from the Precision3D 3D Surface Model, offering accurate global elevation data that captures the true height of terrain, buildings, and vegetation. It provides measurements at 50 cm spatial intervals, delivering high-resolution elevation data for every point on Earth. With an absolute accuracy of 3 meters across all dimensions—achieved without the need for ground control points—the DSM maintains consistency across various surfaces and terrain types.
Digital Terrain Model(DTM): A Digital Terrain Model (DTM) represents the bare earth surface, offering valuable insights into topography and material volumes. The DTM is generated through automated processing that removes vegetation and man-made structures from 3D data, utilizing extensive source image archives.
Point Cloud: The Point Cloud is an RGB-colorized product generated photogrammetrically from the Precision3D 3D Surface Model, and it is seamlessly coregistered with other Precision3D products. It provides precise x, y, and z measurements extracted directly from the 3D mesh, enriched with RGB values taken from the phototextured surface. This enables the delivery of optical land cover information in a format familiar to users of LiDAR data.
Buildings: Maxar’s Precision3D Buildings offer accurate, scalable 3D building data ideal for smart cities, autonomous navigation, population mapping, taxation, and emergency management. They feature precise height details and align seamlessly with other Precision3D products worldwide
