I was trying to point out that, regardless if the units are meters or
feet, when you transform to a different CRS, you change all three values
of the location, x,y and z. For example:

Micha,
It was not a private conversation.
If I understand, you have a vector of points with x,y and z in the
attribute table, and you want to transform to some different coordinate
system, while also transforming the

Daniel,
The points have an elevation -- in feet -- associated with the geographic
location. Is there a grass module that will

Daniel,
Yes, that's the source since db.out.ogr dumps the attribute table.

The lat/long coordinates you get from DB.out.ogr probably comes from your

When you project the data in Grass, the coordinates in the vector geometry
are updated but the attribute table is not changed. Try using v.to.db to

I have precipitation data for all stations within a county. The geographic
coordinates of the source are lon/lat. These were imported to a lon/lat
directory using v.in.ogr then reprojected (v.proj) to the standard state
projection (EPSG 2838).
I want to run spatial analyses on these data in
