librttopo

brew install librttopo v1.1.0 GPL-2.0-or-later

C shared library for constructing and manipulating topology networks and geometries.

Why you might care

Used by PostGIS and spatial databases to handle complex topology operations on geographic data. Provides robust topology validation and manipulation that raw geometry libraries like GEOS don't expose; primarily a build dependency for GIS software rather than a direct CLI tool.
