Hi, Please bump sci-libs/gdal to version 3.1.0, released 2020-05-03, with lots of features and bugfixes (https://github.com/OSGeo/gdal/blob/v3.1.0/gdal/NEWS ), while keeping source (but not binary) compatibility with the current 3.0.4 that is in the Gentoo repo. On my local overlay, I had to drop the patches gdal-3.0.2-complete.patch and gdal-3.0.2-datadir.patch in order for the new version to build; I'm not sure of the consequences, but I didn't see any drawbacks on my side (YMMV, as always).
Maybe you will need this patch too: https://github.com/OSGeo/gdal/commit/2b863dbabdc2a7d724f9fdf3e6ff20a142b619f6 because the new version naming of app-text/poppler-20.08.0 breaks the compilation when the [pdf] flag is used. The patch itself can be found in bug #735828 And btw there is already a newer sci-libs/gdal version upstream - 3.1.2 (https://github.com/OSGeo/gdal/blob/v3.1.2/gdal/NEWS)
This added 3.2.0: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4e34dcaebf06409d6873d12504011279cc70aa77.
