I downloaded a specific layer which has the format "AIG" as you can see in the screenshot.
It has no projection so I applied "Define Projection" on it. I searched for the projection and found the following:
4.1 - INDIRECT SPATIAL REFERENCE SYSTEM:
Type of indirect spatial reference system:
Reference date: 2001.
4.2 - DIRECT SPATIAL REFERENCE SYSTEM:
Datum: Lambert Azimuthal.
Map projection: Projection LAMBERT_AZIMUTHAL
Major Axis 6378388.00000
Minor Axis 0.00000
radius of the sphere of reference 6378388.00000
longitude of centre of projection 9 0 0.000
latitude of centre of projection 48 0 0.000
false easting (meters) 0.00000
false northing (meters) 0.00000
The problem I have is that if search for this projection I get these two
After applying the first one using "Define Projection", nothing changes in the file. By this I mean the spatial reference is still "undefined" and the coordinate system is unknown. I also tried other projections but nothing works. If I convert it to a polygon first, define projection works but the reference on the map is still completely wrong. I think these problems occur because of the "uncommon" raster format?
I also think that the projection from the screenshot is not equal to the one I posted up here?
My goal is to project it in the end to "British National Grid" as all my layers I work with have this projection.
I also tried it on another computer with ArcGIs 10.2 and the same problem occured.
See these FME links for further reference to the AIG format:
