A scalable geospatial information management system and method for the assembly, packaging and online distribution of worldwide geospatial or geographic images and related information. The system includes a cluster computing architecture, capable of metering media and derivative product delivery streams. At the heart of this system is custom content processing, load balancing, caching, and delivery software. The dynamic rendering of geospatial images and related information permits a user to interact with the system to pan, zoom and navigate in real time or near term. The system includes a content management database for storing a worldwide collection of spatially indexed information and supporting metadata. The system also supports the real time generation of derivative products from the geospatial information. |
