Abstract
Systems, methods and articles of manufacture for view based streaming of geographical information system (GIS) data are described herein. An embodiment includes assigning priority values to cache nodes based on a current view of GIS data, reordering cache node requests based on the assigned priority, aggregating the reordered cache node requests into aggregated requests and providing the aggregated requests to a content server to retrieve cache nodes that fulfill the requests. Another embodiment includes receiving cache nodes in response to requests for a frame of data, wherein the cache nodes are associated with a requested view of GIS data, reviewing a priority value assigned to each requested cache node, determining cache nodes that are relevant to a current view and discarding cache nodes based on said determining step.
