Patent number: 8010244Abstract: A system and method for efficient intervisibility determination. The intervisibility determination method of the present invention provides a multiple threat processing capability within a specified area of terrain using a common database. Computation is simplified through the method of processing data posts in the terrain elevation database. By taking integer steps and incrementing distance, x or y, and a predicted elevation value at each step, a small number of operations may be performed. Recomputing a change in elevation value may be reduced. An umbra database provides an enhanced look-up capability for displaying and updating the intervisibility display information. The systems and methods of the present invention may be suitable for use on a vehicle and in mission management activities.Type: GrantFiled: September 12, 2007Date of Patent: August 30, 2011Assignee: Lockheed Martin CorporationInventors: Mark Allstadt, Marc Blais, Ira S. Glickstein, Peter N. Stiles, Ronald Vienneau

Patent number: 7769246Abstract: A system and method for multiple map image projecting and fusing in an object oriented computer environment. The multiple map image projecting and fusing method may provide a flexible and efficient architecture for generating combined map images from one or more map data sources. One or more map image objects may be coupled to map data objects, map projection objects and other map image objects according to a contemplated use of the invention.Type: GrantFiled: February 17, 2009Date of Patent: August 3, 2010Assignee: Lockheed Martin CorporationInventor: Marc Blais

Patent number: 7738679Abstract: A system and method for creating a connectivity framework between map image objects and map data objects in an object oriented computer environment. The connectivity framework may provide a flexible and efficient architecture for generating multiple map images from one or more map data sources. The map image objects may be coupled to map data objects and map projection objects.Type: GrantFiled: February 2, 2009Date of Patent: June 15, 2010Assignee: Lockheed Martin CorporationInventor: Marc Blais

Patent number: 7705852Abstract: Compressed graphic image data files, such as Compressed ARC (Arc-second Raster Chart/map) Digitized Raster Graphics (CADRG) map files for a region of interest, are stored in blocks of memory (nodes) preferably arranged as a linked list. Portions of files containing data for an area of interest including an image of interest are decompressed before the data are sent to a frame buffer for display. Nodes that do not contain requested data are flagged as unused, but not deallocated, making the data in such nodes available for use or replacement.Type: GrantFiled: July 3, 2007Date of Patent: April 27, 2010Assignee: Lockheed Martin CorporationInventor: Marc A.
