Re: [GRASS-user] Null values in attribute table get converted to 0 (zero) during v.to.rast

I was traveling so could not respond. So sorry to chime in a bit late. For me it was a bit counter intuitive that polygons with null attributes became zero in the finished raster. What if I had attributes with zero value in it? I liked the idea of issuing a warning and using the `where`

Hi Daniel, I agree that if there's a NULL in the column, there should be NULL in the resulting raster. I suggest to open a ticket here: https://trac.osgeo.org/grass/ Cheers, Vero El jue., 24 oct. 2019 a las 14:40, Daniel Victoria (< daniel.victo...@gmail.com>) escribió: > Hi list, > > I have a

[GRASS-user] Null values in attribute table get converted to 0 (zero) during v.to.rast

Hi list, I have a vector polygon map that I'm converting to raster. The attribute column that I process has some empty rows (no data / null). When I run v.to.rast, these empty rows become 0 (zero) on my resulting raster map. Shouldn't v.to.rast respect the empty attribute table and create null
