This dataset was created by the Kentucky Transportation Cabinet, Division of Planning. Questions should be directed to the Data Management Branch Manager at (502) 564-7183.
Version 6.2 (Build 9200) ; Esri ArcGIS 10.9.1.28388
Attributes fall within three categories: structural attributes, descriptive attributes, and calculated attributes. Structural attributes uniquely identify individual arcs and are verified against fields in related Oracle tables. Descriptive attributes are compared against KYTC internal documents and field inspections. Calculated attribute fields are populated via script routines.
mixed
Manual inspection and GPS in-field validation.
Node, geometry and topology relationships are collected or generated to satisfy topological requirements. Some of these requirements include: arcs must begin and end at nodes, arcs must connect to each other at nodes, and arcs do not extend through nodes.
Data completeness for unrevised digital files reflects the content of the source graphic ie. DRGs, DOQQs, realignments, As-Builts, field maps and other agencies' documents. All future updates will be collected following the current Standards for KYTC Road Centerlines (see http://giac.ky.gov/giac_standards_trans.htm).
Accuracy of unrevised/pre-GPS files are based on the use of source graphics ie. 1:24000 DRGs. The target horizontal accuracy for the road layers was 1:24,000 (+/- 40 feet). Given the variety of sources for the data, it is recognized that the older centerlines do not always meet published national map accuracy standards. For data currently being collected and all GPS-based road centerline data, the KYTC Division of Planning uses the geospatial positional accuracy standards proposed by the Federal Geodetic Control Subcommittee (FGCS 1994). Road centerline collection methods are based on pseudorange measurements (FGCS Classification Band IX). These differential GPS (DGPS) methods, either in post processed or real-time modes, provide a resulting horizontal accuracy of less than 4 meter radius of the relative positional error circle with a 95% confidence. The target accuracy for new collection is sub-meter (< 1.0 meter), but it is recognized that some field conditions prevent attaining this. All county level coverages will have a published accuracy statement containing a relative positional error radius and a confidence level.
