Difference between a floating point Digital Elevation Model (top) and an integer Digital Elevation Model (bottom) — especially noticeable in flatter areas.
- Digital Elevation Models (DEMs): LAND INFO offers multiple DEM options, including coverage we custom create from stereo pairs and DEMs produced directly by satellite operators DigitalGlobe and Astrium.
- Vector Feature Extraction: accurate extraction of layers such as buildings, hydrology, transportation and other infrastructure.
- Object Based Image Analysis will reduce costs and speed turn-around on your next land-use/land-cover, vegetation, impervious surface or change detection mapping project.
