[GRASS-user] Distance layer

[Nomad Rain]

Hello GRASS group!

Currently  I  try  to  make  an  environmental  application - a script
implementing  one  of  the  atmospheric polution models. The algorithm
demands  to  include the function which returns the value depending on
distance from the polution source.

Thus,  I want to calculate the layer of distances (first map) from the
only pollution source (point on second map).

I cannot find the command which can automaticaly return the value of
distance between two pixels on two maps.

Does anybody know how to do it (find the distance betw. 2 pixels)?

I use grass-6.2.0RC2

Thanks in advance.
