I´m using ArcGIS v10 ArcInfo.
I´m working with a feature class that has 5 features which are waterdepths (1 to 5m). These features are overlapping each other. What I need, is that they are not overlapping. To achieve this I used two differend methods that are leading to the same goal:
I extracted each feature in a single feature class (1, 2, 3, 4, 5). 1 is the biggest overlapping 2, 3, 4 and 5. So I erased 1 with 2, 2 with 3, 4 with 5, merged them and had the feature class I needed.
I ran the union-tool (geoprocessing) on the feature class itself. The problem is, that all overlapping parts are created additionally as new features. Instead of the 5 features I need, I get 10 features more which I have to sort and erase by hand.
My question: Is there a tool or method that does this without so many steps by hand? I´m able working with QGIS and ArcGIS v10 ArcINFO.
