Overview
r.quant produces the quantization file for a floating-point map.
The map parameter defines the map for which the rules are to be created. If more than one map is specified, then this implies that the floating-point range is the minimum and maximum of all the maps together, unless either basemap=map or fprange=min,max is specified.
Quant rules
The quant rules have to be entered interactively.
If rules is specified, the input has the form:
value1:value2:cat1:[cat2]where value1 and value2 are floating point values and cat1 and cat2 are integers. If cat2 is missing, it is taken to be equal to cat1. All values can be "*" which means infinity.
Note
It is an error to specify both basemap and fprange.
