SYNOPSIS

13       t.rast3d.algebra
14       t.rast3d.algebra --help
15       t.rast3d.algebra     [-sng]      expression=string      basename=string
16       [nprocs=integer]   [--help]  [--verbose]  [--quiet]  [--ui]
17
18   Flags:
19       -s
20           Check  the  spatial topology of temporally related maps and process
21           only spatially related maps
22
23       -n
24           Register Null maps
25
26       -g
27           Use granularity sampling instead of the temporal topology approach

41   Parameters:
42       expression=string [required]
43           Algebraic expression for temporal and  spatial  analysis  of  space
44           time 3D raster datasets
45
46       basename=string [required]
47           Basename of the new generated output maps
48           A  numerical  suffix separated by an underscore will be attached to
49           create a unique identifier
50
51       nprocs=integer
52           Number of r3.mapcalc processes to run in parallel
53           Default: 1

DESCRIPTION

56       t.rast3d.algebra performs temporal and spatial map  algebra  operations
57       on  space  time  3D  raster  datasets (STR3DS) by using the temporal 3D
58       raster algebra.
59
60   NOTES
61       The module expects an expression as input parameter  in  the  following
62       form:
63
64       "result = expression"
65
66       The  statement  structure  is  exact the same as of t.rast.algebra, see
67       t.rast.algebra but allows four-dimensional indexing.
