The Open Geospatial Consortium (OGC) is currently preparing its next major Innovation Initiative, Testbed-19, which builds upon the success and outcomes of Testbed-17, Testbed-18, and other Collaborative Solution and Innovation (COSI) Program Initiatives (formerly the OGC Innovation Program). Testbeds provide a unique opportunity for sponsors to work with the world’s leading geospatial IT experts to tackle location data & processing challenges together. OGC is now inviting any potential sponsor organizations to bring forward their technology integration and other technological challenges. Responses are due by December 31, 2022. Challenges put forth by sponsoring organizations will be refined and mapped to a set of work items that OGC member organizations will compete to address. The OGC COSI team (formerly the Innovation Program), together with the sponsors, will then select the most qualified organizations to join Testbed-19 and help solve these challenges.
