ET GeoWizards for ArcGIS 10.1 + Crack Keygen/Serial Date added: Jan 2016. You'll have to figure out which tools to use if you want to avoid writing code. ET GeoWizards is a set of powerful functions that will help the ArcGIS users to manipulate data with ease. Obviously this is just a rough outline of the method. The shapes to 3D and finding the highest vertex.ĭraw minimum spanning tree of all points.ĭefine shortest path between first and last points, this is yourįelixIP reported that they used this method in a Python script, and it took 3 days for 2 technicians to successfully delineate 100s km of levee ridgelines in Australia. If you don't know where the river banks are, make the lines long enough to extent past where the riverbanks would be (a hillshade might be helpful for that).ĭefine the highest point on each perpendicular, eg by interpolating ( Robert Buckley achieved this automatically with ET-Geowizards.) Make sure each perpendicular line is long enough to reach the riverbanks. With few clicks draw draft of levee.)ĭraw perpendiculars at small steps along the purported thalweg line You already generated a rough draft of the thalweg line, so you can skip the first two steps outlined by FelixIP (Use hillshade image of dem as background. Taking the method explained by FelixIP in this answer and adapting it to your situation, we get the following steps:
