This directory contains a SWI-Prolog pack for spatial reasoning. It has been developed by Willem van Hage and was originally distributed as part of the SWI-Prolog source. Due to the relative small user base and not-so-easy-to-install dependencies it has been removed from the core sources.
- libgeos
- libspatialindex
On recent Debian versions (bullseye) these may be installed using
apt-get install libspatialindex-dev libgeos-dev
