Group region on float raster

[Anne-MarieDubois]

Hello everyone,

Is there a way to use the equivalent of the Group region tool but for float raster? (ERROR 000969) I don't want to interger, I want to calculate region based on float value.

Kind regards,

There is no such tool, but a method could be employed with its own limitations.

If you want to retain some of the decimal precision for some reason, scale up the float raster by a factor of 10, take its integer value, perform the regiongroup.  You can always scale back the resultant zones by dividing by the factor used in the first step.  For example

a = regiongroup(int(raster * 10))

b = a/10
