Methods, systems, and apparatus, including computer programs encoded on computer storage media, are disclosed for track simplification and correction. In one aspect, a track data set having track points defining a course can be accessed and inaccurate track points and incorrect track points can be identified, wherein identifying inaccurate track points includes comparing, for one or more of the track points, a dilution of precision (DOP) value associated with the track point to a DOP threshold, and identifying incorrect track points includes performing an error correction process. Also, a corrected track can be generated by removing identified inaccurate track points and incorrect track points from the track data set. Further, identifying an inaccurate track point can include determining that the DOP value associated with the track point exceeds the DOP threshold. Additionally, the DOP threshold can be specified by user input.
