Just a quick question. I have been playing with the SRTM data, and have
noticed that the data comes in WGS84 ellipsoid. I am looking to convert
these heights to MSL. Does anyone know of anyway to do this within
GRASS??
The only thought that I have had so far was to import the WGS84
ellipsoid heights, and use r.mapcalc to subtract. However, just a quick
look at the data, that would not really work. Has anyone had any
experience with having to do this?? Thanks!!

Hi everybody,
I come back actively to the list.
And I begin with this question: How can I rectify a vector file? We need
make a rectification as with an image, but with a vector grass file.
Thank You.

Hi Alexandre Rodier,
this can be done with v.transform.
See the related man/html page.
