Another new algorithm introduced in eCognition v9.4 is the NDSM layer calculation which will calculate the NDSM based on your input layers DSM and DTM. This is a straight forward way to calculate this very helpful layer which helps to easily discriminate elevated and non-elevated features. After calculation, an NDSM layer is added to your project. You can use this layer to improve your segmentation / classification / refinement etc. Enjoy!
