[GRASS-dev] Retiling functionality for 2D raster?

[Markus Neteler]

Hi,

for voxels, we have the r3.retile module to subset a volume:
http://grass.osgeo.org/grass70/manuals/r3.retile.html

I am lacking a "r.retile" module to easily split a big 2D raster
map into tiles, e.g. for parallelized analysis on a cluster.
To go the v.mkgrid way might be a bit tedious.

Any ideas? (Ab)use the segment lib to achieve this?

thanks,
Markus
