ABSTRACT
Aerial photography is used to gather information about an area without being indirect contact with it. Besides satellite imagery, air photos are most commonly takenfrom planes that fly specific paths to gather spatial information of an area. Air photoscan be applied to a variety of uses that can vary from, analyzing traffic congestion in acity, to land use/land cover analysis, real estate, and mapping.
A Global Positioning System (GPS) was created by the military for navigationaland locational purposes. Over the past several decades the GPS has become a usefulmapping tool. By taking specific latitude and longitude points, a GPS system gatherspoints, lines, and regions aiding cartographers in creating a more accurate map of an area.
Governor Dodge State Park is located in Dodgeville, WI, its one of the mostscenic and beautiful parks in the state. By gaining aerial photographs through the LandRecords and Zoning Office, and using such resources along with the GPS information,one can map a scenic region such as a national or state park. This is accomplished bycombining data collected from a GPS unit and a detailed aerial photo/ground analysis ofthe given area (in this scenario, Governor Dodge State Park). Air photos are proved to beaccurate by using the GPS unit to ground truth the actual trails, thus providing visitorswith an accurate and extensive trail guide.
