Abstract: 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.

Abstract: A digital Earth system based upon a hexagonal subdivision of a polyhedron representation of the Earth utilizes a computer-implemented method for assigning identifiers. The method comprises defining a tessellation of hexagonal cells, the tessellation having a first axis and a second axis, the first axis being perpendicular to a first side of the hexagonal cells, the second axis being 120 degrees from the first axis and being perpendicular to a second side of the hexagonal cells; selecting an origin cell for the tessellation and assigning a unique identifier comprising a first value and a second value thereto; and assigning a unique identifier to each cell other than the origin cell, the unique identifier for each of these cells comprising a first vector value and a second value, the first vector value and the second vector value being indicative of the location of the cell to the origin cell along the first and second axis respectively.
