Summary:A method implemented by a computer with a processor and a memory storing instructions executed by the processor includes mapping a geographic input region to a set of blocks. For each block in the set of blocks, ellipsoidal geographic coordinates of the geographic input region are transformed to flat coordinates. The block is stored in a primary index when the block does not contain a boundary of the geographic input region. The block is stored in a secondary index when the block does contain a boundary of the geographic input region.
