DESCRIPTION

36       d.correlate  displays graphically the results of a r.stats analysis run
37       on two raster map layers. This module highlights  the  correlation  (or
38       lack of it) among data layers (scattergram).
39
40       The  results  are  displayed  in the active display frame on the user’s
41       graphics monitor. d.correlate erases the active frame before displaying
42       results. If no graphics monitor is open, a file map.png is generated in
43       the current directory.
44

NOTES

46       If three or four map layers are specified, the correlation  among  each
47       combination of two data layers is displayed.

EXAMPLE

50       Scatterplot   of  two  LANDSAT  TM7  channels  (North  Carolina  sample
51       dataset):
52
53       g.region raster=lsat7_2002_30 -p
54       d.correlate map=lsat7_2002_30,lsat7_2002_40
55       Scatterplot of two LANDSAT TM7 channels
