Name: Jefferson County KY Buildings with Building Heights
Display Field: PTD.bg.BG_NAME
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The BG theme represents roofline boundaries of manmade structures identifiable from aerial photography. A building is a manmade structure which may be habitable by human beings, animals or which stores materials and is at a minimum 10' x 10' in roof top area. A building may house a variety of activities at one time, or sequentially over its life. A feature classified as building but not having a roof (silo, tank or water tower) will show outline of the features shape. Planimetric and Topographic mapping of Jefferson , Kentucky. The Jefferson County layers use the Horizontal 1983 North American Datum, Kentucky State Plane North Zone. New data was digitized by NV5 in Spring 2025 using recently acquired imagery from Spring 2024.
