H2GIS is a spatial extension of the H2 database engine in the spirit of PostGIS. It adds support for managing spatial features and operations on the new Geometry type of H2, the Open Geospatial Consortium (OGC) Simple Features for SQL (SFSQL) functions and additional spatial functions that we (the CNRS) develop.

H2GIS uses Maven. To launch a full build (including tests), run the following command:

$ mvn clean install
