About:
Librttopo is the RT Topology Library, an open-source C library designed to manage and process spatial topologies. It provides robust support for the OGC SFA (Simple Features Access) specification, enabling complex spatial operations like validation and conversion. Its primary value is serving as a foundational dependency for spatial databases like SpatiaLite to handle advanced geospatial data integrity.

Key Features:

OGC SFA-compliant topology engine
Spatial data validation and integrity checks
Conversion between geometry and topology models
C library for high-performance integration

Use Cases:

Building topology-aware geospatial applications
Validating spatial data integrity in databases
Serving as a backend for SpatiaLite topology functions

Alternatives:

PostGIS – PostGIS is a full spatial database extension that includes topology features, whereas Librttopo is a standalone library focused specifically on topology management.
