Type: enhancement | Status: new
Priority: major | Milestone: 7.0.1
Component: Raster | Version: unspecified
Keywords: r.clump classification | CPU: Unspecified
Platform: Unspecified |
------------------------------------+-------------------------
r.clump should be able to maintain the categories of original raster, this
is really useful for classified maps.
An example
{{{
i.group group=lsat7_2000 sub=lsat7_2000
in=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30,lsat7_2000_40,lsat7_2000_50,lsat7_2000_61,lsat7_2000_70,lsat7_2000_80
i.cluster group=lsat7_2000 sub=lsat7_2000 signature=cluster_sign classes=5
# the output has 5 classes
i.maxlik group=lsat7_2000 sub=lsat7_2000 signaturefile=cluster_sign
output=lsat7_2000_maxlik
# the output now has something like 21000 classes, it should be able to
maintain the 5 original classes
r.clump in=lsat7_2000_maxlik out=lsat7_2000_maxlik_clump
}}}
