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.[2] 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.

Software that supports SpatiaLite

  • Desktop:
    • ESRI ArcGIS since version 10.2 as "Database Connection".[3]
    • QGIS supports SpatiaLite native since version 1.1[4]
    • AutocadMap 2013
    • Global Mapper[5]
    • OpenJUMP offers a Plug-In.
    • FME (also available as server)
    • TileMill renderer (uses Mapnik) reads SpatiaLite as data source.[6]
    • Spatial Manager Desktop,[7] Spatial Manager for AutoCAD,[8] Spatial Manager for BricsCAD [9]
  • (Web)Server:
  • Tools and libraries:
  • Web Apps:
    • GeoConverter - Free online data converter which reads and writes several GIS vector file formats (based on OGR), including SpatiaLite.[19]

Standards

SpatiaLite supports several open standards from the OGC and has been listed as a reference implementation for the proposed GeoPackage standard.[20]
