I work with ArcGis 10.2. I want to Combine (Union?) two Polygons FC of waterdepths, both having the same classification but not the same elements. I want to keep all the elements and all the initial values where the elements don't overlap and only the highest value where they do. I want to use a model builder to do this.
The issue could be resolved in raster but I have too many datasets of different hydrological orders, meaning the main rivers run across a third of Germany whereas the secondary ones are sometimes just small auxiliaries.
Does anyone has already done something like that? How was it solved?
I hope that made sense. I will clarify as much as needed.
