Abstract: Measure-up processes described herein provide data that enable three-dimensional (3D) positioning of a tip of a bucket of an excavator. The processes may include steps of curling a bucket of the excavator in and out, moving a stick of the excavator in and out, and moving the bucket so that it touches a point at different bucket angles. During each of the steps, data is generated using a tilt compensating survey pole and one or more inertial measurement units (IMUs).

Abstract: A computer-implemented method of providing georeferenced information regarding a location of capture of an image is provided. The method includes receiving a first image at an image-based georeferencing system, the first image comprising digital image information and identifying a cataloged second image that correlates to the first image. The method further includes automatically determining reference features common to both the second image and the first image, accessing geographic location information related to the common reference features, utilizing the geographic location information related to the common features to determine a georeferenced location of capture of the first image and providing the georeferenced location of capture for access by a user of the image-based georeferencing system.

Abstract: Target augmentation makes GIS data collection devices more intuitive and useful for GIS workers, and reduces GIS data collection errors.

Abstract: A method for matching a region on an object of interest with a geolocation in a coordinate system is disclosed. In one embodiment, an image of a region on an object of interest is captured on an image capture device. The image is processed to detect a located feature using a feature detection algorithm. Further processing of the located feature is performed to derive a first feature descriptor using a feature descriptor extraction algorithm. The feature descriptor is stored in a memory. A database of feature descriptors having geolocation information associated with the feature descriptors is searched for a match to the first feature descriptor. The geolocation information is then made available for access.

Abstract: A method of automatic obstacle location mapping comprises receiving an indication of a feature to be identified in a defined area. An instance of the feature is found within an image. A report is then generated conveying the location of said feature.

Abstract: Embodiments provided herein recite methods and systems for an accuracy estimator for a position fix. In one embodiment, a solution receiver for receiving a code solution and at least one additional solution from a different solution technique is utilized. In addition, a table of metric values comprising an associated accuracy estimate for at least one characteristic of each of the code solution and the at least one additional solution is also utilized. A comparator compares the code solution and the at least one additional solution with the table of metric values. In addition, a solution orderer orders the at least one additional solution above or below the code solution dependent on whether the at least one additional solution is within a pre-defined offset distance threshold. If the at least one additional solution is outside of the distance threshold, the code solution is chosen as the final solution.

Abstract: According to embodiments, a method of logging position data is provided. An indication of a desired accuracy value for determining a geographic position is received. A geographic position is then received. A predicted post-processed accuracy value for the received geographic position is then calculated. The desired accuracy value is then compared with the predicted post-processed accuracy value for the received geographic position. When the predicted post-processed accuracy value for the received geographic position is at least as precise as the desired accuracy value, the geographic position is logged.
