Abstract: Systems, methods, and other embodiments associated with generating aggregate data geospatial grid cells for encoding in vector tiles are described. In one embodiment, a method includes identifying a subset of finest-resolution geospatial grid cells contained by a vector tile in a set of finest-resolution geospatial grid cells and their associated aggregate data values; selecting a cell resolution level based on a zoom level of the vector tile; generating a new geospatial grid cell at the cell resolution level based on cell IDs of the subset of finest-resolution cells; generating a total aggregate data value for the new cell based on associated aggregate data values of the subset of finest-resolution cells; encoding the new cell and total aggregate data value in the vector tile; and transmitting the encoded vector tile to a client to cause the vector tile and the new cell to be displayed.
