“Data”, or perhaps “Data and Mapping”? The data part of this could include discussions about sources of (open) data, approaches to sharing data, encouraging common standards and re-use of data, technical approaches to implementing data, etc. I’ve added the “Mapping” bit, as these two often seem to crop up together, with mapping being an application that people want which relies heavily on data, and so it a good use-case for working out the details of what’s needed.
