Abstract: An imaging system includes a 3D database for storing data relating to three-dimensional site model images having a vantage point position and orientation when displayed. A 2D database stores data relating to a two-dimensional image that corresponds to the vantage point position and orientation for the three-dimensional site model image. Both the three-dimensional site model image and two-dimensional imagery are displayed typically on a common display A processor operative with the two-dimensional and three-dimensional databases and will create and display the three-dimensional site model image and two-dimensional imagery from data retrieved from the 2D and 3D databases and correlates and synchronizes the three-dimensional site model image and two-dimensional imagery to establish and maintain a spatial orientation between the images as a user interacts with the system.

Abstract: A video surveillance system may include a geospatial model database for storing a geospatial model of a scene, at least one video surveillance camera for capturing video of a moving object within the scene, and a video surveillance display. The system may further include a video surveillance processor for georeferencing captured video of the moving object to the geospatial model, and for generating on the video surveillance display a georeferenced surveillance video comprising an insert associated with the captured video of the moving object superimposed into the scene of the geospatial model.

Abstract: A computer-implemented method for generating an image-textured digital surface model (DSM) for a geographical area of interest including both buildings and terrain may include using a computer to generate a digital elevation model (DEM) of both the buildings and terrain for the geographical area of interest. The method may further include providing a collection of optical images including oblique optical images for the geographical area of interest including both buildings and terrain. The computer may also be used to selectively superimpose oblique optical images from the collection of optical images onto the DEM of both the buildings and terrain for the geographical area of interest and to thereby generate the image-textured DSM for the geographical area of interest including both buildings and terrain.

Abstract: A system and method determines a Line-of-Sight volume for a specified point within a three dimensional model. Each data file includes data about geometric entities that make-up a geographic feature that may impact a Line-of-Sight from a focus. A processor is operative for processing the data files and creating a series of polygons that represent a shell of a Line-of-Sight volume to the focus at a specified resolution based on the process data files.
