[GRASS-user] a student needs help with v.surf.rst...

Hello,
I’m trying to produce an elevation model with this interpolation method.
So while the v.surf.rst doing the work i’m suddenly (just before the green bar reaches the end) getting this message “out of memory”.I must say that my area of interest is little big. Any suggestions ? Thanks in advance…

here’s the region and the vector info :

north: 4585700
south: 4512450
west: 397250
east: 511325
nsres: 25
ewres: 25
rows: 2930
cols: 4563

Number of lines: 25180

What kind of machine are you using? i.e. how much RAM do you have? and how
high of a data density do you have?

In the mean time, try running v.surf.rst on a smaller region. Also have a look
at the segmax parameter.

Cheers,

Dylan
