Learn about how to use the "Surface Calculation" algorithm in the Trimble eCognition Software.

This algorithm allows you to compute Slope and Aspect based on your elevation raster. The results can then be used for your analysis, detecting high slope areas facing south, high risk areas for landslides, discriminating different vegetation types and many many more!

We will talk about theory and show you how to compute both layers (Slope and Aspect) in a project. Finally as a little cherry on top we show you how you can create a 3D point cloud within eCognition holding attribute values of image objects! In our case we will create a Point Cloud with the slope and aspect information for each pixel, colorize and display it in 3D (actually just for fun & the thumbnail ;)).
