Abstract
A high-performance gridded database protocol for storing, arranging, and extracting gridded data includes associating values for a single grid cell and storing them together to extract as many useful values as possible from a single read operation. Gridded data is stored in a geographically-indexed cylindrical grid that permits efficient data extraction for a particular location while maximizing efficiency of read operations. Cylinders of values are built by grouping grids that are related to each other so that when data for a location is to be extracted, a minimal number of read operations is needed to retrieve an entire stack of data relevant to the location.
