I tried to locate a ref pt and compare the lat-long in Google Maps and in ArcMap. I am not certain, but it seems like the coastline of Bornholm in the Google Maps map (Tele Atlas) is approx 300-400 m to the west of the coastline in the ArcMap map. The ArcMap map data we use is very accurate since it is used e.g. for radio coverage calculations with rasters that have 50x50 metre cell size.
Does anyone have accuracy numbers for TeleAtlas (google) maps in Denmark?
