I have two datasets in ArcGIS Desktop. One is from the Ordnance Survey (UK National Mapping Agency) and, when I view the properties of the dataset it says that the Spatial Reference is
I want to set another file to the same spatial reference. I know I can use the Import function to import it from the first file, but how would I select this coordinate system from the built-in ArcGIS ones? I can find
British National Grid under Projected/National Grids/Europe and I can find
OSGB 1936 under Geographic/Europe, but I can't seem to find the combination of the two anywhere?
I'm not hugely experienced with coordinate systems, but I think that BNG is the co-ordinate system, and OSGB 1936 is the datum. Is that correct?
I know that when I select spatial references in ENVI I can choose a coordinate system of
United Kingdom and a Datum of
OSGB1936. Is there a way to do this in ArcGIS Desktop?
