TxDOT_Roadways_Unsegmented
<span>The Texas Department of Transportation (TxDOT) maintains a spatial dataset of roadway polylines for planning and asset inventory purposes, as well as for visualization and general mapping.  This dataset covers the state of Texas and includes on-systems routes (those that TxDOT maintains), such as interstate highways, U.S. highways, state highways, and farm and ranch roads, as well as off-system routes, such as county roads and local streets. <span style='font-weight:bold;'>Route segments in this unsegmented version are not broken by functional classification</span> the way the other version of </span><a href='https://txdot.maps.arcgis.com/home/item.html?id=008906d83772435bb757cb76c9644e5d' target='_blank' rel='nofollow ugc noopener noreferrer'>TxDOT Roadways</a><span> feature layer is.<br /><br />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, along the line.  M-enabled networks serve as frameworks for locating roadway assets along the network using linear referencing.  This data set must be downloaded as a file geodatabase in order keep M-values intact. If downloaded as a shapefile or added to a map from a connection to ArcGIS online, measures will not be applied to the line.<br /><br />Update Frequency: Monthly<br /><br /></span><div><span>Source: Geospatial Roadway Inventory Database (GRID)</span><br /></div><div><span><br /></span></div><div><span>Security level: Public<br /></span></div>
