FY2015 GSS-I Plans Acquire and process medium and large urban areas with suspected growth. Continue efforts to streamline GSS-I data evaluation: Improve address matching Conflate spatial files Work with 2020 Address Canvassing Groups to align GSS-I file acquisition with 2020 Census design.
SDCs and the GSS-I Join us as we work to coordinate efforts amongst all groups working with state and local geospatial data: State Data Centers (SDCs), National States Geographic Information Council (NSGIC), Federal-State Cooperative for Population Estimates (FSCPE), Census Bureau Coordination may include: Identifying where address or road data does not exist, Identifying owners of address and geospatial data in your state, and sharing this information between our groups. Participating in Census sponsored webinars to discuss topics like partner file status, data issues, future directions etc.
