Abstract: The present disclosure is directed to systems and methods for providing a stable topological representation of pathway networks as well as features associated with these networks. The disclosure is exemplified using road networks which have applications in mapping, navigation, and autonomous vehicles. Extensions may be learned through practice of the disclosure. Utilizing implementations disclosed herein may provide advantages for data conflation between different mapping systems and map data while improving overall stability by developing a common reference standard that is tied to semantic features rather than abstract geographic representations.

Abstract: A position fix identifying a geographic location of a receiver is received. The position fix was generated using signals received at the receiver from respective high-altitude signal sources (such as satellites). Imagery of a geographic area that includes the geographic location is also received. The imagery is automatically processed to determine whether one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated. In response to determining that one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated, the position fix is identified as being potentially erroneous.

Abstract: The present disclosure is directed to methods and systems for generating a geodetic datum. The geodetic datum can establish a coordinate system and/or a set of reference points that describe the respective locations of a portion or all of Earth and/or objects located thereon. In general, a computing system can generate the geodetic datum using various sensor data from one or more sources including: satellite imagery, aerial imagery, aerial light detection and ranging data (LIDAR), ground-level imagery, ground-level LIDAR, and/or other forms of sensor data. This data can be used as a reference dataset that can be combined with additional sensor data (e.g., a second dataset) to determine correspondences between overlapping areas represented in the datasets. Continuing this process for regions that collectively cover the Earth can be used to create a geodetic datum of the entire Earth, without using a mathematic abstraction of the Earth surface.

Abstract: Systems and methods for image registration using data collected by an electronic device, such as a mobile device, capable of simultaneous localization and mapping are provided. An electronic device, such as a mobile device, can be can be configured to collect data using a variety of sensors as the device is carried or transported through a space. The collected data can be processed and analyzed to generate a three-dimensional representation of the space and objects in the space in near real time as the device is carried through the space. The data can be used for a variety of purposes, including registering imagery for localization and image processing.
