I want to georeference a scanned map of Sudan (Africa) as .jpg file format,coordinate points are marked on scanned map in 4 degree intervals. I am not familiar to georeferencing in ArcMap. So looking for a detail guide line for georeferencing in ArcMap (using 4 control points) and also looking for a guide line to edit the spatial reference in base map with the suitable PCS information for the AOI. In my previous post in this forum I have mentioned the problem that I am facing at the time of georeferencing. Guide line will help me out.


Thanks in advance,

Simran.
