I often use eCognition in geomorphometry. The watershed segmentation algorithm is great for that, but something that I really would like to see is flow accumulation. Currently, I generate flow accumulation in a GIS and then bring it in as a layer, but often I need to run flow accumulation on a dataset that was modified in eCognition. For instance, after identifying water bodies (using imagery) in eCognition and then flattening them in the DEM, I would like to run flow accumulation. It is a hassle to export the modified DEM, run flow accumulation in a GIS, and then bringing it back into eCognition. Also, it makes automation/operationalization of such workflows impossible. Flow accumulation is useful for a range of things, including stream/wetland mapping (i.e. combining it with land cover mapping), DSM2DTM conversion, and height above river drainage (flood risk) calculations.
