1. A data improvement system, comprising:
an initial database comprising a plurality of data fields representing initial data, which includes at least one of the following: track data, identification data, location data, position data, heading data, curvature data, type data, grade data, coordinate data, cross track error data, centerline data, initial modeling data, positioning system data, geographic information system data, time data, log data, prediction data, feature data, train data, collected data, dynamic data, batch data, or any combination thereof; a verification database comprising a plurality of data fields representing subsequent data, which includes at least one of the following: track data, identification data, location data, position data, heading data, curvature data, type data, grade data, coordinate data, cross track error data, centerline data, initial modeling data, positioning system data, geographic information system data, time data, log data, prediction data, feature data, train data, collected data, dynamic data, batch data, or any combination thereof; and a processing device in communication with the initial database and the verification database and configured to:
receive at least one data field from the initial database and at least one data field from the verification database; anddetermine verification data based upon the at least one data field from the initial database and the at least one data field from the verification database, wherein the verification data includes at least one of the following: error data, correction data, flagged data, corrected track data, corrected train data, or any combination thereof, wherein at least one of the initial database, the verification database, and the processing device is configured to receive source data, wherein the initial data includes initial track centerline data for a specified position on a track or segment of track, and the subsequent data includes subsequent track centerline data for the specified position on the track as derived from the source data, the processing device further configured to determine verification data in the form of improved track centerline data based at least partially upon the initial track centerline data and the subsequent track centerline data, and wherein the initial track centerline data defines a centerline of the track, and wherein the subsequent track centerline data defines another centerline of the track. |
