[GRASS-user] filtering csv file before input for v.in.ascii

[Veronica Andreo]

Hi Helmut,

Did you download from GBIF site? Because there are 2 (that I know) R
packages that allows you to download data from GBIF, and you can ask for
"NO SPATIAL ISSUES" in the data (among other options), probably in that way
you can avoid these coordinates that are in a different reference system.
Does that make sense?? Ah! The packages are: rgbif and dismo

If you want, I can provide an example... I just tried yesterday :)

HTH,
Vero
