The large incomplete red cells are IG1 cells (see Step 1: Country). The yellow cells within these cells are IG2 cells, each 5°x2.5° in size. The smaller 5×5 IG3 cells in each IG2 cell are 60’x30’ (minutes) in size. The white dot is at IG3-265721. Again, in the final product each cell location will be an active cell, and can be selected to zoom into a smaller area, or to select the spatial search criteria.
