Plus, the output makes for some seriously cool artwork - it's like bringing the river to life in a whole new way.Ĭreated using OpenTopography's RiverREM package that automates the detrending process. I guess I haven't been exploring enough in the world of geospatial analysis!īut let me tell you, when you detrend a DEM to show river features, the results are nothing short of amazing. I've done some tinkering in raster analysis before, working with canopy height models to obtain forest metrics, but I never thought about using it to identify fluvial features. ![]() Detrending DEMs to show river features sounds like the coolest thing since sliced bread, don't you think?
