Choice of Coordinate Systems for Wide Areas:

  • Mapping_CoordinateSystems_WideAreas: Discussion of coordinate systems and the errors each can introduce when mapping large areas (cloned from IVSG on 2023 04 03).The coordinate system conversions through simulation work are as below.

Simulation post processing:

  • FeatureExtraction_Association_PointToPointAssociation: Functions are provided to determine matches between data sets of (X,Y) points, store and compare groups of associated points (patch objects), and determine intersections between patch objects and circular arcs (useful for collision detection).
