Georeferencing an Aerial Photograph

A picture of Nicolas MalloyAuthor: Nicolas R. Malloy

Today, most students have little direct experience with film-based photographs. However, there still may be a high volume of film-based historic photographs stored in basements and file cabinets of federal, state, or municipal government agencies as well as non-profit organizations. When you want to bring these images into a GIS, georeferencing is required. In this activity, you will georeference an aerial photo with the help of NAIP imagery downloaded from the USGS Earth Explorer.
