VDOT_INTERSECTION_W_XY This feature class consists of approximately 125,000 features representing over 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS). Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. Incases where routes are noncontiguous (e.g. a valid physical gap exists), multi-part geometry is created. The feature class also depicts overlapping routes (e.g. Interstate 64 and Interstate 95) as two separate collinear features, one on top of the other. Routes built in the prime and non-prime directions are included. Each road centerline record has a master route record assigned. This feature class is best suited for labeling roadways when overlap reference is needed. Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions). Note: The overlap and non-prime measures are for reference only and have not been fully validated for accuracy or completeness.
