It also has a tool to visualize the z-values (or reflectance spectrum) of a rectangular area such as the surface profile below: With the stereo analyst extension, you will be able to collect and measure 3D features using photogrammetric principles from stereo pairs of imagery.ĮRDAS Imagine has a tool that slices your elevation data into a user-defined number of bins, each containing the same amount. You will need an additional license for a stereo analyst. Additionally, it has geoscientific tools to remove void areas, extract valleys and ridges, and drape images in a virtual GIS viewer. We’ve also included a side-view profile in this example.ĮRDAS Imagine can generate your basic slope, aspect, contours, and viewshed types of maps.
It paints each range based on its elevation as in the example below.
The painted relief raster splits elevation into color ranges.
Whether you have a photogrammetric, LiDAR-based, or InSAR digital elevation model, ERDAS Imagine can perform most types of terrain analysis.
