Is there an all-in-one installer that allows having all open-source gis apps installed in windows 8.1? with all apps I mean for instance postgresql, postgis, mapserver, qgis, grass.
I have cygwin installed, but I've read that it's way better to install these apps in windows. In case I need to query my psql db located in my postgresql windows installation from cygwin (ie. shell terminal), could that be possible?
