Aerial Photography and Airborne LiDAR Set the Stage for Community’s Planning Needs
Wheeling, West Virginia
CT’s geospatial team performed aerial photography and airborne LiDAR for the City of Wheeling, WV, and the surrounding area covering nearly 30 square miles.
Ground control was surveyed at targeted locations. Initial delivery was color digital orthophotography at a .25’ pixel resolution, and limited planimetric mapping of the roads and surface utility features. The project was to provide a new base map to enhance and expand the water and sewer utility GIS mapping program. Components are now in place for design scale mapping anywhere in the coverage including design scale mapping, water and wastewater GIS mapping, and stormwater surface modeling.
