    Abstract: The present invention pertains to geographical image applications. A user may transition between nadir and street level imagery using unstitched oblique imagery. Oblique images offer a rich set of views of a target location and provide a smooth transition to or from other images such as nadir photographs taken by satellites or street level photographs taken by ground level users. Using unstitched oblique images avoids artifacts that may be introduced when stitching together one or more images. This allows an application to display images to a user and create the illusion of three dimensional motion.

    Abstract: Embodiments relate to evaluating structures located in a geographic area that is divided into divided bounding areas using a three-dimensional environment representing the structures. In an embodiment, a computer-implemented method includes a method for dividing a three-dimensional environment depicting the structures into the divided bounding areas where each divided bounding area encompasses a portion of structures. In the method, an evaluation web page for each divided bounding area is retrieved from a structure evaluation server where each evaluation web page provides an evaluation status for each divided bounding area. At least one structure encompassed by a selected divided bounding area is evaluated based on a visual representation of the structure. An updated evaluation web page for the selected divided bounding area is provided to the structure evaluation server where the updated evaluation web page provides an updated evaluation status for the selected divided bounding area.

    Abstract: Systems and methods for generating textures to be rendered in conjunction with a polygon mesh are provided. More particularly, a polygon mesh modeling a geographic area can be accessed. A plurality of source images depicting the geographic area can then be identified. The plurality of source images can be aligned to reduce projection misalignments between source images when the source images are projected to the polygon mesh. A texture can then be determined based at least in part on a weighted average of pixels in the plurality of source images corresponding to a point on the surface of the polygon mesh. Determining a texture can include removing at least one outlier pixel associated with a moving object from the weighted average.
