help we with using conical equal area projection for maps in GRASS
Hello Mohammed,
could you be a bit more explicit ? what is your problem ? where is
located your data ? and so on...
No one can really guess what you need.

Perhaps a good way to proceed is to read some documentation for a first
approach. This document
https://subversion.gdf-hannover.de/dl.php?download=gdf_grass60_v1.2_en.pdf can help you, especially chapters 4 to 6.
In a few words, you have to create a location according to your
projection parameters (type, datum, ellipsoïd, etc.), another location
in XY coordinate without geocoding in which you import your rasterized
map. Then you can proceed georeferencing from local location towards
target location.
Good luck,
Vincent.
