I have a problem with a shapefile (EPSG:31287 MGI_Austria_Lambert). I tried to solve it on my own, but I just have no clue as to what's the error.
So I use a basemap from basemap.at (WMTS: https://www.basemap.at/wmts/1.0.0/WMTSCapabilities.xml -> EPSG:3857 - WGS 84 / Pseudo-Mercator). When importing the basemap and then the shapefile in QGIS it looks like a weird distortion (Austria shapefile), the Polygons (which represent houses) are not exactly over the houses in the basemap, but a few meters away. When I do the same in ArcMap, there is no Problem and every Polygon matches the house in the basemap.
But I need to export it as KMZ or KML and when I do so, and then import it in Google Earth I get the same distortion like in QGIS)
I really hope someone has a clue or knows where the problem stems from.
