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.

Some automated and semi-automated tools for linear feature extraction in two and three dimensions

A system for advanced vector editing, comprising a routing calculation server and a rendering engine. The routing calculation server calculates a radius around a visual cursor associated with a raster image; determines a three-dimensional location at the cursor from the raster image; determines a three-dimensional path using epipolar geometry; and recalculates a vector path through the cursor location according to the three-dimensional path.

Automated registration of three-dimensional vectors to three-dimensional linear features in remotely-sensed data

A system for automated vector updating, comprising a database that stores raster and vector information, and a vector processing server that algorithmically processes vectors for updates, and methods for algorithm-based vector updating.

A system for advanced vector editing, comprising a vector analysis server that analyzes vector information, a routing calculation server that calculates routes from the vector information, and a rendering engine that produces visualizations from the routing information, and several methods for advanced vector editing in two- and three-dimensional visualizations.

Advanced semi-automated vector editing in two and three dimensions

A system for automated conversion of two-dimensional hydrology vector models into valid three-dimensional hydrology vector models, comprising a vector extraction engine that retrieves vectors from, and sends vectors to, a vector storage, a DSM server that retrieves a DSM from a DSM storage and computes a DSM from stereo disparity measurements of a stereo pair retrieved from a raster storage, and a rendering engine that provides visual representations of images for review by a human user, and a method for automated hydrology vector model development utilizing the system of the invention.

Automated conversion of two-dimensional hydrology vector models into valid three-dimensional hydrology vector models

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.

Semi-automatic extraction of linear features from image data

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, 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.

A method for extracting a linear feature from remotely sensed imagery, including selecting by user interface anchor points for the linear feature, the anchor points being identified with a geographic location; using image-based logic to automatically calculate a vector set associated with the anchor points, the vector set comprising a path associated with the linear feature; automatically attributing a material type to the path; automatically attributing a geometry to the path; selecting by user interface anchor points for a successive linear feature; using image-based logic to calculate a successive vector set associated with the anchor points for the successive linear feature, the successive vector set comprising a successive path; using a geometric relationship between the vector set and the successive vector set to automatically adjust the vector set to create an adjusted vector set, the adjusted vector set correcting the path associated with the first linear feature.

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.
