Here's a sample of what you can do with this language
-- Count White Walkers 500m around "The Wall"
SELECT COUNT(*) AS NB_WHITE_WALKERS
FROM CREATURES CREA, LOCATIONS LOC
WHERE
ST_INTERSECTS(ST_BUFFER(LOC.THE_GEOM, 500), CREA.POSITION)
AND LOC.NAME = 'THE WALL'

The developer documentation can be found on the Github wiki.
H2GIS is developed since 2014 by a team of French researchers and engineers from CNRS, experts in GIS and computer science.
The team has extensive experience in spatial analysis and algorithms. It is also a fervent defender of open science, promoting the development and use of open-source tools, the use of geospatial standards and the production of open data. H2GIS is fully in line with this dynamic.
H2GIS also benefits from the active support of the French UMRAE laboratory, which contributes to the code and documentation.
