Various embodiments are described herein for systems and methods for allowing user at a client terminal to interacts with a graphical user interface having a DGGS globe to perform spatial analysis on DGGS spatial data based on a spatial query on unified spatial data that may be obtained from distributed geospatial data sources having different data formats. The spatial analysis results can include a resulting collection of cells that can be displayed on the DGGS globe and/or aggregated spatial statistics that can be displayed in a DGGS legend at the graphical user interface. In one aspect, the spatial analysis can be iteratively performed to obtain a refined resulting collection of cells and aggregated spatial statistics. In another aspect, the resulting cells and/or aggregated spatial statistics can be added to a geospatial data source that can be accessed by another client terminal that is performing other geospatial analysis.
