G-REQS (Geospatial in-situ Requirements) is a database tool and a standard methodology designed to collect user-driven requirements for in-situ datasets in the context of the Group on Earth Observations (GEO). G-REQS is open to contributions and users from agencies, initiatives, networks, research infrastructures, private companies, institutions, and public organizations in search for fit-for-purpose Earth observation in-situ datasets.

The G-REQS website is still under development and is currently hosted across two different domains with complementary functionality, we encourage you to explore them both and make use of all they have to offer. Please note that in future we are planning to merge everything onto one single platform, so stay tuned for our exciting developments to come!
