[GRASSLIST:4889] ID given Distance from a given point's ID

[Thomas Dewez]

Dear all,

Here's a question that I can't seem to resolve myself. I created a 
map of randomly spread pixels with r.random and buffered those 
with r.buffer. For each pixel of the buffer zone, I am interested in 
knowing from which source pixel (pixel ID or x,y) I am closest. One 
way to do this is by giving the ID of the point which fall inside a 
buffer zone. But how could I do this practically?

Cheers,

Thomas
