Description: The Road Centerline data layer (VT Road Centerline) contains all town and state highways, as well as many private roads. The centerlines were originally developed under contract by Greenhorne and O'Mara under the guidance of the Vermont Center for Geographic Information (VCGI) in 1992. VCGI was the original steward of the road centerline data between 1992 and 2004. The Vermont Agency of Transportation (VTrans) is now the steward of this data layer.Updates have been performed over the years by VCGI, Regional Planning Commissions, and VTrans. VTrans has taken over the update and maintenance of the road centerline data layer and has revised the layer to match "Official" highway mileage. This layer is the most reliable source for official VTrans road class (AOTCLASS) information. However, this layer may not include every private road, and the road name information may not match the VT E911 Road Centerlines data layer. The VT E911 Road Centerlines road centerline layer maintained by Vermont's E911 Board has the most up-to-date roadname information. It is similar to this data layer, but it includes all private roads and generally has more reliable road name and address range information. There was a significant change in the schema in the June 2013 release as part of the effort between VTrans and E911 to merge their two datasets. The data layer includes the field structure agreed to by both entities, but many of the fields that are E911's have not been populated in this release. Due to software limitations, field attribute details are not included in the metadata associated with this release. Field attribute details are available in the "VTrans Road Centerline Spatial Data User Guide" available online through the Vermont Open Geodata Portal (http://geodata.vermont.gov/datasets/VTrans::vt-road-centerline), the VTrans Mapping Section website (http://vtransmaps.vermont.gov/Maps/Publications/VTrans_Road_Centerline_User_Guide.pdf), or by contacting the VTrans Mapping Section.
