A geospatial modeling system may include a geospatial model database for storing images of a geographical area and a reference digital surface model (DSM) of the geographical area. The images each have associated with them respective first geolocation data with a first accuracy. The reference DSM may include second geolocation data with a second accuracy being greater than the first accuracy. The geospatial modeling system may further include a processor cooperating with the geospatial model database for generating an initial DSM based upon overlapping portions of the images, and aligning the initial DSM based upon the reference DSM to generate a georeferenced DSM having a third accuracy greater than the first accuracy.

Geospatial modeling system for images and related methods

A method () comprises steps of: receiving a first digital model () of a first three-dimensional scene comprising at least one object; receiving a second digital model () of a second three-dimensional scene comprising at least one object; and performing a change analysis () on the first and second digital models to provide a difference indication representing a difference between the first and second models. In one embodiment a mean square error operation () is performed on the first and second digital models to provide a value indicating the difference between the digital models. In another embodiment, a conflation operation is performed on the difference model provided by the change analysis () and an object level change database () is produced.

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.

A computer implemented method is for processing a digital elevation model (DEM) including data for a plurality of objects. The method includes determining a perimeter versus area parameter for each object in the DEM, and comparing the perimeter versus area parameter for each object to a threshold to identify whether each object in the DEM is a building or foliage.

A computer implemented method is for processing an original digital elevation model (DEM) including data for terrain and a plurality of objects thereon. The method includes generating a lower-resolution DEM from the original DEM, and generating an objects-only DEM based upon a comparison of the lower-resolution DEM and the original DEM. The method further includes reducing noise in the objects-only DEM.

A polarized material inspection device that includes a light source, a first polarizing filter disposed within the optical path of the light source, a frame into which a second polarizing filter is disposed, and a support for positioning the frame such that an object may be viewed through the second polarizing filter. In the preferred embodiment, the first polarizing filter is rotatable through a ninety degree arc such that planes of polarization may be adjusted to be parallel or orthogonal to one another. The preferred embodiment also includes a light illumination assembly having a rotatably mounted linear polarizer at the polarizing output end. This light assembly is attached to a portion of the frame and may be adjusted such that the beam of light is directed to the desired portion of the surface. Within the frame is mounted a fixed linear polarizing filter of sufficient size to allow the entire illuminated surface to be viewed. The frame is mounted to an adjustable support arm that is attached to a tripod or other support to allow the apparatus to be fixed during a given procedure.

An automated method is for making a topographical model of an area including terrain and buildings thereon based upon randomly spaced data of elevation versus position. The method may include processing the randomly spaced data to generate gridded data of elevation versus position conforming to a predetermined position grid, processing the gridded data to distinguish building data from terrain data, and performing polygon extraction for the building data to make the topographical model of the area including terrain and buildings thereon.

A set of pickup truck protective pads for carrying long loads comprises a cab pad and a tail gate pad both of a configured elastomeric foam having preferably a tough skin or cover. The cab pad has generally a right angle shape in cross section and a beveled leading edge and the tail gate pad has generally a U-shaped cross section. Each pad has a hold down strap with clips on either side to secure it to the truck.
