I have a basic model on which I’d like to do some terrain analysis (ie. flow, slope). The model was produced by several sections that were lofted together (straight sections) and then the edges (ridges/valleys) were filleted with a 10m radius.
Once I exported the terrain model info into GIS/Global Mapper and made a slope analysis, I noticed that, because the transitions between slope gradients in the sections were angular, it produced something like kinks in the slope. These can be seen clearly using Environment Map. These then affect the way water flow patterns are mapped on the surface, etc.
Is it possible to smooth the transitions between these edges in the model? Or will I need to remodel the terrain somehow?
