The Geospatial Data Extension provides comprehensive spatial data management capabilities for CKAN, enabling geographic search, spatial metadata handling, and integration with geospatial standards and protocols for enhanced geographic data discovery and visualization. This essential extension implements spatial indexing using PostGIS, geographic bounding box search functionality, and map-based dataset discovery interfaces with interactive geographic filtering capabilities. The system supports multiple geospatial metadata standards including ISO 19139, INSPIRE, and FGDC, with automatic spatial extent extraction from geographic datasets and metadata documents. Advanced features include CSW (Catalog Service for Web) server implementation for standards-compliant spatial data catalog services, spatial harvesting from remote geospatial catalogs, and integration with OGC web services including WMS, WFS, and WCS for direct data access. The extension provides coordinate reference system transformation, spatial validation tools, and geographic data quality assessment capabilities. Administrative features include spatial index management, geographic metadata validation, and batch processing tools for spatial data operations. Integration capabilities extend to external GIS systems, spatial databases, and mapping services with support for popular formats including Shapefile, GeoJSON, KML, and GML. The system provides RESTful spatial APIs, geographic RSS feeds, and integration with mapping libraries for enhanced visualization. Essential for organizations publishing geospatial data, environmental agencies managing spatial datasets, government portals implementing spatial data infrastructure, and research institutions where geographic data discovery, spatial search capabilities, and compliance with geospatial standards are critical for effective spatial data management and accessibility.
