Hi.
I am trying to split raster map into chunks to do calculations (with
r.mapcalc) on each chunk separately.
I browsed the net and found only the script called r.split.line, which
needs vector file to split raster, but this is not that I want.
Is there a way to split raster by rows? For example
hi
Is there a way to split raster by rows? For example if I have a GeoTiff
file with 8000 rows I want to split it into 8 files 1000 row per each.
r.info (http://grass.osgeo.org/grass64/manuals/html64_user/r.info.html) to
get the raster extent
g.region
The function r.tileset (
http://grass.osgeo.org/grass64/manuals/html64_user/r.tileset.html) allows
you to split your raster layer in user-defined tiles (which could be a tile
of one row). The description states that it produces tilings of the source
projection for use in the destination region and
