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.
