UN-GGIM

This session examines the current state-of-the-art in aggregation and disaggregation of geographical data, and discusses potential approaches in the development of new methodologies and tools, particularly from a geographic location perspective. In order to enable a better understanding and reporting of the SDGs' status and progress, the SDG indicators need to be disaggregated with specific categories of interest or locality (a "top-down" approach), or aggregated from sub-national to national to global scale (a "bottom-up" approach). The Interagency and Expert Group on SDG Indicators Working Group on Geospatial Information (IAEG-SDG WGGI) concluded that geospatial information is able to provide enabling methodologies for disaggregating and aggregating data across both demography and geography and has organized a Taskforce Stream to address these issues.The session will report the achievements and activities by IAEG-SDG WGGI.
