Geometry Type: esriGeometryPolyline

Description:
A control section is a unique identifier for individual segments of a roadway. Historically control sections were only assigned to on-system, or state-maintained, highways, and were created as a highway referencing system for planning and maintenance projects, etc. However, this dataset also includes off-system, or non-state-maintained, roadways. Control Section numbers are assigned for the life of the roadway and generally do not change or move, regardless of improvements to the roadway. Currently, control sections are located geographically along roadway using linear referencing. The data was created by the TxDOT Transportation Planning and Programming Division's Data Management Section.

This data contains measures. Measures are stored as M-values within each vertex along the line, in the same way that some datasets store z-values for the elevation, except that measures store the distance from the origin, or DFO, of the line. M-enabled networks serve as a framework for locating roadway assets along the network using linear referencing. This data set must be downloaded as a file geodatabase in order to keep M-values intact. If downloaded as a shapefile or added to a map from a connection to ArcGIS online, measures will not applied to the line.
