ArcGIS Meets Your Expectations

At Esri, we use open APIs and open source to maintain an open system, one that allows transparency and interoperability.

Engage with Open APIs

Engage with Open APIs

Our open APIs provide unparalleled access for various systems (GIS and others) to engage and communicate with the ArcGIS platform. This includes both client and server technologies. Therefore, any open source GIS desktop clients have the ability to use our services. We are committed to sharing internal R&D work where applicable.

Build with Open Source

Built with Open Source

The ArcGIS platform implements and leverages open-source technologies, such as GDAL. We support Red Hat Enterprise Linux and SUSE Linux. Geodatabases can live in the PostgreSQL database. ArcGIS for Server can use open source web servers, such as Apache Tomcat and Oracle GlassFish, to share GIS services.
