Dear all,
How can I know the size occupied by one raster map?
The 2G size limit for each map consider the sum of
all files that is part of the map, or for each individual
file?
I just created a map=null() using r.mapcalc, and the
..\newLocation\PERMANENT\cell_misc\myMap\null
file is about 1.6GB.
Dear Helmut and Markus
I checked out the Helmut's suggestion, and in fact are there a MinGW-w64
that is a mix between 32-64b. I think it is a very promising solution for
windows-based users, mainly because many of new computers that we buy for
GIS end-users area, in general, with large memory (4Gb
Hi Glynn, sorry my delay on answer.
So under windows we are really limitted to 2Gb
independent of compile using LFS flag? :-(
Are there plans to by pass this!?
I hope windows users could also be favoured
of GRASS for work with large maps on near future.

Hi Maven,
do you think that if you have min = -1267650600228229401496703205376.00
is the same value you used on r.null setnull=-1.26765060022823e+030 ?
I think following the Hamish's suggestion you will get there :-)

I recently heard back from Graham Fogg here on campus, and he is in favor of
allowing T-PROGS to be used within GRASS. However, he is still waiting for
the final go-ahead from the original author.

Thanks a lot you both.
I had actually thought of using r.to.vect to get a point map with all
the pixel centres, then v.to.db to get their coordinates etc., but the
maps are too large and resolution too high. Obviously r.mapcalc was
the solution I was looking for, I just regret not noticing it

Ok my bad. I didn't have python-wxgtk2.8 installed.

I have seen the docs,but I am not sure the usage of it.

Hi:
I have a geotiff now, and some cells have a not-expected value, so I want to
Interpolation them, and I notice that there is a command named r.fillnull,
however the cell to be changed is not null, so I want to :
1) change the special cell value to null
2) use the r.fillnull to Interpolation.
