Hello,
I have meteorological data that are on diverse grids, in general associated
with a specific projection. For example, a lambert conic projection has
a 'natural' grid associated, just like the lon-lat grid is a natural grid
for lon-lat pprojection. Then I would like to intersect a vector

nested or non-linear?
or for a lambert conformal 'natural' grid (which are the examples
I have) or any other grid that could arise, is there a simple way to do
a vector corresponding with that

in my base map (called X) I have a few null values and, in Y map I want to
eliminate pixels that match with null values in X. How can I do this?
besides using mapcalc

Markus,
Thanks! This is the first build error I've encountered with GRASS. I'll
get the new code and build it today.

Hi Kim,
You can use r.univar to compute univariate statistics of
your raster data.

Hello Kim,
You can use the module r.series. Like this, if you have few images:
r.series input=image1,image2,image3... method=average output=averaged_image
Or if you have a

Hello Jenny,
I don't know if it is a coincidence, but your problem can be solved in the
same way as Kim's problem.

Input is always a vector map with points, net is an optional input
vector map with lines for a network, e.g. if you want densities of
road accidents along a road network and not per grid cell.
Thank you for this explanation. Are these just GRASS conventions, or are
they specific to v.kernel?
