Use cases

• Catalog geospatial datasets with semantic search
• Serve OGC/STAC-compliant APIs for GIS clients
• Build interactive maps from cataloged data

Pros

• Standards-based (OGC/STAC) for interoperability
• Combines semantic search with geospatial indexing
• Self-hosted, full control over data and deployment

Cons

• Small project community (217 stars) may limit support
• Requires setup and maintenance of PostGIS and pgvector
• User interface maturity likely limited compared to commercial platforms
