31 input=name [required]
32 Name of input raster map
33
34 output=string [required]
35 Output base name
36
37 width=integer [required]
38 Width of tiles (columns)
39
40 height=integer [required]
41 Height of tiles (rows)

43 overlap=integer
44 Overlap of tiles
45
47 r.tile retiles an existing raster map with user defined x and y tile
48 size.
49
51 r.tile generates a separate raster for each tile. This is equivalent
52 to running g.region along with r.resample in a double loop.
53
54 The module can be used to split a large raster map into smaller tiles,
55 e.g. for further parallelized analysis on a cluster computing system.
56
57 The overlap is defined in rows/columns.

60 Retiling example for the North Carolina DEM:
61 g.region raster=elevation -p
62 # rows: 1350
63 # cols: 1500
64 # generating 2 x 2 = 4 tiles (width=1500/2, height=rows/2)
65 r.tile input=elevation output=elev_tile width=750 height=675
66 creates 4 tiles with the prefix elev_tile (named: elev_tile-000-000,
67 elev_tile-000-001, elev_tile-001-000, ...).
