1. A track database data improvement system, comprising:
- a source database comprising a plurality of data fields representing source 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, positioning system data, geographic information system data, survey data, log data, dynamic data, batch data, or any combination thereof; and
a processing device in communication with the source database and programmed or configured to;
determine initial track data for a specified segment of track based at least in part upon the source data, the segment having end points;
determine error data based upon the initial track data and a straight line between the end points, and create intermediate segments as defined as a straight line between intermediate end points;
determine trimming data for at least two of the intermediate end points, thereby defining trimmed track segments; and
provide at least a portion of the trimming data to a track database;
wherein the trimming data includes at least one of the following;
first end point data, second end point data, coordinate data, heading data, grade data, linear distance data, track type data, or any combination thereof.

Abstract
A data improvement system, including an initial database, a verification database, and a processing device in communication with the initial database and the verification database. The processing device receives data from the initial database and the verification database, and determines verification data based thereon. A track data improvement system and a track database improvement system are also disclosed.
