摘要： A data visualization technique rapidly loads images to decrease data transfer time and associated bandwidth cost for animation effects in displays of data, and includes initially loading raster imagery at a coarser zoom level than a current view on the display, and then manipulating the imagery using general-purpose image manipulation algorithms to interpolate data points as a user adjusts the zoom level. In this manner, the data visualization technique intentionally displays a coarser view than that selected, rather than transferring entirely new imagery or datasets, and manipulates the imagery as necessary to avoid loading more data from a remote server to the local client each time the user adjusts the view.

摘要： 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.
