Elevation data provides the 3rd dimension.

If you are a developer in a defense and commercial industry who uses geospatial imagery, you have likely seen an increasing need for spatially accurate, 3D representations to aid in your analysis.

The ENVI DEM Extraction Module allows you to quickly and easily create spatially accurate digital elevation models (DEMs) of your geospatial imagery. With the module's flexible, step-by-step, fully guided process, you can produce accurate and robust models from virtually any airphoto or satellite stereo pair images with RPCs, including those from pushbroom sensors such as ASTER, IKONOS, OrbView-3, QuickBird and SPOT 1-5.

You can use DEMs independently or use them as a basis for additional analysis, such as orthorectification, topographical analysis, line of sight analysis, and contour map generation.

The ENVI DEM Extraction module saves you time and improves your image analysis workflow with flexible viewing, measurement and editing tools to enhance your 3D representations. These tools are all you need to view anaglyph stereo pairs, measure building or mountain heights, edit DEM values and extract 3D features.
