SpatiaLite

Spatial Database

SpatiaLite is an SQLite database engine with spatial functions added.

SQLite is a popular DBMS, simple, robust, easy to use and really lightweight. Each SQLite database is simply a file; you can freely copy it, compress it, send it on a LAN or WEB with no complication at all.

The files are also portable; the same database file will work on Windows, Linux, MacOs etc.
