If you know the data is actually WGS84 then you should do a coordinate system override and select LL84 as your cs.

I create a dataconnection with GDAL provider, using a Geotiff from ArcGIS 9.3.1. This GeoTIFF contains the coordinates, and when I add the newly created layer to a map, it detects automatically the initial map view correctly. However, the layer is displayed in meters instead of decimal degrees. I checked the config file from the dataconnection, and the projection is LOCAL_CS["*XY-MT*",LOCAL_DATUM["*X-Y*",10000],UNIT["Meter", 1],AXIS["X",EAST],AXIS["Y",NORTH]] But the GeoTIFF is supposed to be in WGS84 (for the little story, the image is captured from Google Earth in MapWindow using the Shape2Earth plugin, then I import it in ArcGis to export it as a GeoTIFF; ArcGIS open it with decimal degrees, and if I open the GeoTiff in another GIS software, the GeoTiff is detected as WGS84 too; so to me it's definitely something with MGOS) How can I fix this ?
