[GRASSLIST:4937] A question

[Kevin Slover]

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!!
