[GRASSLIST:848] Ellipsoid Shift For GRASS Vector Map

[Vidya Kotamraju]

Hello all,

I have a GRASS vector map that has been converted from a toposheet.This 
vector map is based on the "everest" spheroid/ellipsoid.I have a few 
GRASS raster maps that are based on the "WGS84" ellipsoid.

I need to overlay the vector map on these raster maps.

How do i go about converting the ellipsoid of the vector map from 
everest to WGS84 ? What command can i use ? I am not sure if i can us 
the "m.datum.shift" command for this. However, if i can go ahead with 
"m.datum.shift", what values do i need to provide in the lat and lon 
parameters of the command?

any pointers ?

Regards,
Vidya Kotamraju.
