SpatiaLite

SpatiaLite is an open-source library that extends SQLite with full spatial database capabilities, implementing the OGC Simple Features specification. It transforms SQLite, the world's most widely deployed database engine, into a capable spatial database that supports geometry storage, spatial indexingSpatial IndexingSpatial indexing organizes geospatial data into efficient data structures that dramatically accelerate location-based... via R-tree, coordinate transformations, and the complete set of spatial SQL functions for geometric analysis. SpatiaLite supports all OGC geometry types and provides spatial functions for relationship testing (ST_Intersects, ST_Contains, ST_Within), constructive operations (ST_Buffer, ST_Union, ST_Intersection), measurement (ST_Area, ST_Length, ST_Distance), and coordinate transformation via PROJPROJPROJ is the foundational open-source library for cartographic projections and coordinate transformations used across .... It includes tools for importing and exporting Shapefiles, GeoJSONGeoJSONGeoJSON is an open standard format for encoding geographic data structures using JavaScript Object Notation (JSON).

SpatiaLite's key advantage is its serverless, zero-configuration architecture inherited from SQLite. A complete spatial database is contained in a single file that can be copied, shared, and versioned.
