I'm really new in working with Geospatial Libraries and I was able to install GDAL and PostGIS already. I just wanted to check if I was really able to include the packages GEOS and PROJ4 that is a requirement for PostGIS.
What command lines should I type in to check their versions or if they are installed? Thanks!
Edit (I just need the proj4 checking):
PostGreSQL version :
$ psql --version
PostGIS version : Connect to your database,
=# SELECT PostGIS_full_version();
$ gdal-info --version
$ geos-config --version
I recommend using
pkg-config if you can as it allows you to query
and actually just detailed all of that in a comment to the sf repo which is also in the geo-spatial space.
edd@max:~$ pkg-config --atleast-version=2.1.0 gdal && echo "Yes we are good" edd@max:~$ pkg-config --atleast-version=2.1.0 gdal || echo "Insufficient" Insufficient edd@max:~$
I don't have
proj4 installed so I can't illustrate that.
Edit: I spoke too soon -- I do have it:
edd@max:~$ pkg-config --modversion proj 4.9.2 edd@max:~$ pkg-config --atleast-version=4.9.0 proj && echo "Yes" Yes edd@max:~$
