It seemed to be easy but make big problems, perhaps it is a beginner mistake. Anyway I have to ask you: I need to lay two shapefiles over each other to make a spatial query. The coordinate systems of both shapes are unknown. But I now the one shape was projected in ETRS-1989_LAEA originally; it is a download from here (Berlin). The other shape file was projected in DHDN_Soldner_Berlin.
Now I tried to project the first shapefile to its original coordinate system with the tool “define project” and did the same with the second one. Loading both shape files with different coordinate systems to a data frame the shapefiles are not lying over each other. So I tried to import both to a feature dataset in the File geodatabase. The feature dataset got the coordinate system from the first shape so ETRS-1989_LAEA. Then I import both shapefiles to the feature dataset in the File geodatabase. But this is also not working; the shapes are not laying over each other.
But did I wrong, how can I get both shapes which having different coordinate systems over each other? On the fly is also not working, when I project the coordinate systems from one shape.
Projecting the first shape in the coordinate system from the second shape with the tool “project” is working. But load both shapes having DHDN_Soldner_Berlin as coordinate system to ArcMap 10.2 is again not working.
I read in the forum about the issue but I cannot find my mistake.
Here is the extent from the first shape
Here is the extent from the second shape
