SpatiaLite¶
Spatial Database¶
SpatiaLite is an SQLite database engine with spatial functions added.
SQLite is a Database Management System (DBMS) which is simple, robust, easy to use and very lightweight. Each SQLite database is simply a file. You can freely copy it, compress it, and port it between Windows, Linux, MacOs etc.

Full Spatial metadata in line with OpenGis specifications
Numerous Geometry notations - EWKT, GML, KML, and GeoJSON
Importing and exporting to shapefiles
Coordinate reprojection via PROJ.4 and EPSG geodetic parameters dataset
Locale charsets via GNU libiconv
Spatial Index based on the SQLite’s RTree extension
Access shapefiles as VIRTUAL TABLEs, enabling standard SQL queries on external shapefiles, without importing or converting them
Access external CSV/TxtTab files or xls spreadsheets as VIRTUAL TABLEs
Access XML documents, stored BLOB compressed binary objects, including syntactic “well formed” and XSF schema validation constrained checks. Specific support for ISO-Metadata, SLD/SE styles and SVG graphics.XML documents can be queried using standard XPath syntax.
