SpatiaLite

SpatiaLite is a spatial extension to SQLite, providing vector geodatabase functionality. It is similar to PostGIS, Oracle Spatial, and SQL Server with spatial extensions, although SQLite/SpatiaLite aren't based on client-server architecture: they adopt a simpler personal architecture. i.e. the whole SQL engine is directly embedded within the application itself: a complete database simply is an ordinary file which can be freely copied and transferred from one computer/OS to a different one without any special precaution.

SpatiaLite extends SQLite's existing spatial support to cover the OGC's SFS specification. It isn't necessary to use SpatiaLite to manage spatial data in SQLite, which has its own implementation of R-tree indexes and geometry types. But SpatiaLite is needed for advanced spatial queries and to support multiple map projections. SpatiaLite is provided natively for Linux and Windows as a software library as well several utilities that incorporate the SpatiaLite library. These utilities include command line tools that extend SQLite's own with spatial macros, a graphical GUI for manipulating Spatialite databases and their data, and a simple desktop GIS tool for browsing data.

As it is a single binary file, SpatiaLite is also used as a GIS vector format to exchange geospatial data.

Standards
SpatiaLite supports several open standards from the OGC and has been listed as a reference implementation for the proposed GeoPackage standard.
