Yeah Fibber, i didn't think about it at the time, but we're actually not on the same sheet regarding this. Xavi is calling for something other than what i use and in quite possibly much smaller packaging.
For the Asian operating area you're looking into i use the CBI portion of the
FS2004/FS2002/FS2000 70m Global Terrain Mesh for The Whole World found at SimV:

In order to target just the areas you want, you have to download the terrain map with the link on that page:

I personally use the following for the region:
EA45N24E078 - india-nepal-bangledesh
EA46N24E085 - india-nepal-bangledesh
EA47N24E090 - india-nepal-bangledesh

EA59N28E071 - india-nepal-bangledesh

This all may be a bit more involved than what Xavi is calling for in his readme, so i'll just leave this on your table as another option for enhancing your CBI region. I was initially drawn to the
70m Global Terrain Mesh package because it was a colossal work designed specifically for the MS "civies", giving me the impression of uber quality. I wasn't disappointed, especially wrt flying over the Himalayas and Everest in particular.
