DESCRIPTION

r.tile retiles an existing raster map with user defined x and y tile size.

NOTES

r.tile generates a separate raster for each tile. This is equivalent to running g.region along with r.resample in a double loop.

The module can be used to split a large raster map into smaller tiles, e.g. for further parallelized analysis on a cluster.

EXAMPLE

Retiling example for the North Carolina DEM: 
g.region rast=elevation -p
# rows:       1350
# cols:       1500

r.tile input=elevation output=elev_tile width=135 height=150
creates 108 tiles with the prefix elev_tile (named: elev_tile-000-000, elev_tile-000-001, elev_tile-000-002, ...).
