Evaluating surface data

摘要

Systems, methods, and instructions encoded in a computer-readable medium can perform operations related to evaluating surface data. Geodetic data for a plurality of surface locations are received. The geodetic data may include surface gradient information and/or surface elevation information for multiple surface locations. A set of constraining relationships is generated based on the geodetic data. The set of constraining relationships relates undetermined values of surface elevation movement and/or undetermined values of surface gradient movement to measured surface elevation changes and/or measured surface gradient changes. Some or all of the constraining relationships include multiple undetermined values. Particular values for surface elevation movements and/or particular values for surface gradient movements are calculated for multiple surface locations based on determining a solution to the set of constraining relationships. In some implementations, a minimum curvature surface may be generated deterministically based on the geodetic data and the particular values identified using the constraining relationships.

1. A computer-implemented method for evaluating surface data, the method comprising:
receiving geodetic data for a plurality of surface locations in a geographic region, the geodetic data comprising:
measurements of surface elevation movement for a first subset of the surface locations in a first area in the geographic region; andmeasurements of surface gradient movement for a different, second subset of the surface locations in a different, second area in the geographic region; generating a set of constraining relationships based on the geodetic data, the set of constraining relationships relates undetermined values for surface gradient movements at the first subset of surface locations and undetermined values for surface elevation movements at the second subset of surface locations to the measurements of surface elevation movement and the measurements of surface gradient movement included in the geodetic data, a plurality of the constraining relationships each include multiple undetermined values; and identifying particular values for surface gradient movement at each of the first subset of locations and particular values for surface elevation movement at each of the second subset of surface locations based on determining a solution to the set of constraining relationships.
