Server geospatially organized flat file data

摘要

A flat file data organization technique is used for storing and retrieving geospatially organized data. The invention reduces transfer time by transferring a few large files in lieu of a large number of small files. It also moves the process of locating a given data file away from the file system to a proprietary code base. Additionally, the invention simplifies database management by having quadtree packets generated on demand.

1. A client for receiving and displaying restricted access geospatial data comprising:
an input device, for receiving user input indicating a selection of the restricted access geospatial data to display; a transmission module, for causing a request for the restricted access geospatial data to be transmitted to a stream server, wherein the request includes a session key, wherein the session key includes an identifier of accessible geospatial data, wherein the stream server is configured to selectively grant access to determined particular parts of the restricted access geospatial data based on the session key; a data receiving module, for receiving the restricted access geospatial data from the stream server when the selection is within the identified accessible geospatial data; and an output generation module, for generating and displaying output based on the received restricted access geospatial data.
