I have 2 Shapefiles in CRS 21781. The first one "Gebiete" shows some areas within a ski resort in switzerland. It is downloaded from a WebGIS based on OpenLayers 4 in which it was generated. The second one "Lifte" shows lifts within that same ski resort. This one is exported from ArcMap as a shp, where it was generated.
When I open a new empty project within ArcMap and first add the layer "Lifte" and then the layer "Gebeiete", the layer "Gebiete" is not visualized correctly. Check out the picture and the coordinates in the bottom left corner.
When I first add the layer "Gebiete" I get the correct position and then add the layer "Lifte", "Lifte" is not on the correct position. There must be a problem with the crs, although I kind of thought that if you have the same EPSG codes you are in the same crs...
Honestly I have no clue what's going on here...the prj files are also different, as the ArcMap generated shp doesn't include any EPSG codes, not like the OpenLayers generated shp.
Does anyone know where this problem comes from?
