It is designed to replace the current street centerline layer and street segment table, as it includes the attributes from the street segment table.
Street centerline was originally developed from the road features on the County's 1:2400 base map. Both address range and a link to street names are included as data attributes. The current data is collected from recorded plats in DXF format or is digitized from plats. The data covers the entire County as well as the incorporated Towns.
There are no credits for this item.
