This post seemes to have drowned, so I dare to bump it, hoping that some less confused people like me might anwser to it. I'm using QGIS for years now, but I never figured out how that stuff is supposed to work. One of the reasons why I try to do a lot of stuff now in R is that NA is NA !

hi all!
please, is there someone who could explain properly all the "NoData topic"?

I mean:
1. differences in setting negative values (-999, -9999, -3.40282e +35, etc) VS NoData (Nan, NoData, NULL)
2. how QGIS handles it
3. "best practices" or good hints for managing them

sorry but I've quite a big confusion.

Thank you very much in advance!

Nic
