The SEC holds attributes about sections. In addition to user-defined attributes, the SEC contains information on both the route number and arc number to which the section belongs, the starting and ending positions expressed as percentages of the arc length, starting and ending positions expressed as measures along the route, an internal sequence number and a section feature identifier. See also feature attribute table . A feature class in ArcInfo that is a component of the route-system data model used to implement routes .
