Parameters:
input=name [required]
Name of input raster map
output=string [required]
Output base name
width=integer [required]
Width of tiles (columns)
height=integer [required]
Height of tiles (rows)
overlap=integer
Overlap of tiles
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 raster=elevation -p
# rows: 1350
# cols: 1500
# generating 2 x 2 = 4 tiles (width=1500/2, height=rows/2)
r.tile input=elevation output=elev_tile width=750 height=675
creates 4 tiles with the prefix elev_tile (named: elev_tile-000-000, elev_tile-000-001,
elev_tile-001-000, ...).
