Abstract: A system for vector extraction comprising a vector extraction engine stored and operating on a network-connected computing device that loads raster images from a database stored and operating on a network-connected computing device, identifies features in the raster images, and computes a vector based on the features, and methods for feature and vector extraction.

Abstract: Method for editing a vector set associated with an extracted linear feature in a remotely sensed image, the vector set defining a path and being tied to a geographical location. The method includes displaying the path in a graphical display. Once the user activates a smart editing tool, the user establishes a region of influence centered around a cursor. The region of influence is configured to respond to cursor movements. The user specifies a point near the path and moves the cursor to it, bringing the region of influence along. Any error in the vector set of the path is automatically corrected in real time using image-based logic. The user then previews the correction on the graphical display and implements it, updating the path. The updated path is displayed in real time in the graphical display.

The method includes displaying the path in a graphical display. Once the user activates a smart editing tool, the user establishes a region of influence centered around a cursor. The region of influence is configured to respond to cursor movements. The user specifies a point near the path and moves the cursor to it, brining the region of influence along. Any error in the vector set of the path is automatically corrected in real time using image-based logic. The user then previews the correction on the graphical display and implements it, updating the path. The updated path is displayed in real time in the graphical display.

Abstract: One aspect of the invention is embodied in a number of machine-readable media having stored thereon sequences of instructions which, when executed by a machine, cause the machine to perform a number of actions. The actions include, for each of a plurality of image space coordinates of a camera image, retrieving 1) a corresponding camera position, and 2) corresponding object space coordinates on an object surface that is represented by the camera image. Then, for each of a plurality of height surfaces (chosen with respect to the object surface), a grid coordinate defined by an intersection between the height surface, and a line extending between the camera position and the object space coordinates, is determined. The determined grid coordinates are then associated with their corresponding image space coordinates. Finally, coefficients for a rational polynomial camera model are estimated by fitting rational polynomials to at least the grid coordinates and image space coordinates.
