The first one might be PostGIS, which provides spatial extensions to
PostgreSQL. This packages needs proj, geos, and gdal, and I can also
provide them.
PROJ is in Fedora Extras already. GEOS (first 1.x, the 2.x was needed) and
GDAL have been worked on in old fedora.us QA queue before. After lots of
packaging problems, a circular dependency between GDAL and GRASS (and lack
of decision on how to proceed until a solution would be found/developed)
stopped development of the packages. Meanwhile, one of the solutions
proposed in bugzilla.fedora.us (an interface library for GDAL+GRASS)
has been developed by Debian's GIS community.
For reference, the links to the old tracker:
GEOS - https://bugzilla.fedora.us/show_bug.cgi?id=1394
GDAL - https://bugzilla.fedora.us/show_bug.cgi?id=1964
Packages proposed for inclusion into Fedora Extras should try to avoid
(most of) the issues discussed in there. [The ticket for GDAL has been
an exceptionally long one.]
