Abstract: Embodiments of the invention provide systems and methods of generating a complete and accurate geometrically optimized environment. Stereo pair images depicting an environment are selected from a plurality of images to generate a Digital Surface Model (DSM). Characteristics of objects in the environment are determined and identified. The geometry of the objects may be determined and fit with polygons and textured facades. By determining the objects, the geometry, and the material from original satellite imagery and from a DSM created from the matching stereo pair point clouds, a complete and accurate geometrically optimized environment is created.

Abstract: A system processes and stores electronic messages, voice, facsimile, and other data, in a common network architecture having high availability, high throughput, modularity, and linear scalability. The system has the ability to split processing among multiple server machines without having to split data. Electronic messages and other data are organized into folders for individual usernames. A folder daemon resident on a server utilizes a hashing algorithm to convert a username into a hash value corresponding to the folder under a directory of folders for the network's storage devices under which the electronic messages and other data are stored. Using the hashing algorithm, the folder daemon produces a statistically even distribution of folders across the network's storage devices. The folder daemon acts as a file system abstraction layer for the network. Unique numeric identification numbers are associated with the messages and other data in each folder.
