NAME

r.pi.graph.dec - Graph Theory - successive criteria-based deletion of patches.

KEYWORDS

raster

SYNOPSIS

r.pi.graph.dec
r.pi.graph.dec help
r.pi.graph.dec [-al] input=name [id=string] output=string keyval=integer distance=float neighborhood=string index=string choice=string [seed=integer] [--overwrite] [--verbose] [--quiet]

Flags:

-a
Set for 8 cell-neighbors. 4 cell-neighbors are default
-l
Set to perform deletion for the whole landscape rather than cluster-wise
--overwrite
Allow output files to overwrite existing files
--verbose
Verbose module output
--quiet
Quiet module output

Parameters:

input=name
Name of input raster map
id=string
Base name for the ID raster files
output=string
Name of the output ASCII file
keyval=integer
Key value
distance=float
Bounding distance [0 for maximum distance]
neighborhood=string
Neighborhood definition
Options: nearest_neighbor,relative_neighbor,gabriel,spanning_tree
index=string
Cluster index
Options: connectance_index,gyration_radius,cohesion_index,percent_patches,percent_area,number_patches,number_links,mean_patch_size,largest_patch_size,largest_patch_diameter,graph_diameter
choice=string
Cluster index
Options: smallest_first,biggest_first,random,link_min,link_max
seed=integer
Seed for the random number generation
