[GRASS-user] v.surf.idw G_Malloc

[Matthew James]

Hi Everyone,

 

New grass user J I’m using Grass 6.2.3 on windows using cygwin.

 

I am trying to generate yield maps. I have csv files containing x, y and
yield columns.

 

The yields are calculated at random spots around the paddock.

 

In general these files can be many thousands of points long.

 

I’m first importing them into a vector file using v.in.ascii (seems to me
that the process of importing such files needs to be documented better –
it’s hellish for a new user)

 

When I try to run v.surf.idw I get a “G_Malloc – out of memory error” – this
occurs almost instantaneously.

 

I’m not at all short on resources (have about 2gb of RAM and a huge
pagefile) and I’m wondering if there is some way around this problem.

 

Thankyou,

 

Matt
