Abstract: A system for modeling a roof structure comprising an aerial imagery database and a processor in communication with the aerial imagery database. The aerial imagery database stores a plurality of stereoscopic image pairs and the processor selects at least one stereoscopic image pair among the plurality of stereoscopic image pairs and related metadata from the aerial imagery database based on a geospatial region of interest. The processor identifies a target image and a reference image from the at least one stereoscopic pair and calculates a disparity value for each pixel of the identified target image to generate a disparity map. The processor generates a three dimensional point cloud based on the disparity map, the identified target image and the identified reference image. The processor optionally generates a texture map indicative of a three-dimensional representation of the roof structure based on the generated three dimensional point cloud.

Abstract: An example method is provided in according with one implementation of the present disclosure. The method includes displaying a first screen on a first display of an electronic device and a second screen on at least one second display connected to the electronic device. The method further includes identifying a three-pan gesture received on an input device and rotating a screen orientation of one of the first display or the second display, when the electronic device is connected to a second display, based on the gesture.

Abstract: Provided herein is a method for detecting significant changes to files on an electronic storage device, determining if those changes meet a configurable threshold to be considered significant changes, and take actions by or on behalf of the user to accept or decline the changes before they are committed to the system.
