Run spatial data analysis simply using SQL in your PostgreSQL database!! π
PostGeoDa is a PostgreSQL extension for spatial data analysis. PostGeoDa is developed using C/C++ based on the libgeoda library. By utilizing and the database architecture of PostgreSQL and the spatial index in PostGIS, PostGeoDa has the ability to handle real big spatial data.
PostGeoDa is a free and open-sourced library. It is released under the GNU General Public License (GPLv2 or later). PostGeoDa is developed by Xun Li and Luc Anselin.
PostGeoDa is the first spatial data analysis extension of PostgreSQL to power spatial data services for cloud mapping platforms.
PostGeoDa offers many features of spatial data analysis that run efficiently in PostgreSQL, so there is no need to spend extra time transferring geometries over the network.
PostGeoDa has no dependencies. But it is designed to work with PostGIS to handle big spatial data.
PostGeoDa works seamlessly with the current SQL API frameworks e.g. CARTO SQL API
