Hi,
I am working on a LULC Project in Austria and got several shapefiles from different sources. I really have issues to get them together for Analysis. The attached sreenshot sums it up pretty good. The borders of Austria lie about 500km to far east. I am using a projected coordinate System (MGI_M31) for both, the data Frame and the shapefile. I guess ist some Kind of banality but im really stuck here.
Thanks

Hi Sol and thanks for your answer.
I already used the define projection tool with no satisfying result. I always changed the coordinate system in the catalog which has the same result if I got it right. What you refer to as raster image is the basemap provided by ArcMAp. so I suppose it is displayed as defined in the data frame properties???

Andreas,

Try redefining (not reprojecting) the data to MGI Austria GK Central. Its false easting value is 0, while M31 uses 450km. You should also set a geographic (datum) transformation between MGI and WGS84. Try MGI_To_WGS_1984_3.

Basemaps from Esri almost all use WGS 1984 Web Mercator (Auxiliary Sphere).
