Hi everyone

Is it possible to let r.stats.zonal output raster to be CELL?

Thanks

Try with r.statistics. Unfortunately, there are a few modules with similar functionality, yet they work on different raster data types.

Hi Ming,

r.statistics is not an add-on but part of grass core, so no need to install it. It’s already there :slight_smile:

Best,
Vero

The output of r.stats.zonal should be as accurate as possible, thus in most cases a floating point output is required and produced.

If you want to reduce the accuracy to integer, you can do so by creating a new map with r.mapcalc’s function round() and delete the original output afterwards.
