Foresters and other resource managers have used aerial photographs to help manage resources since the late 1920s. As discussed in chapter 1, however, it was not until the mid-1940s that their use became common. Obtaining photographic coverage was always a problem. For many areas of the world, reasonably complete coverage did not exist until after World War II. In addition, aerial photographs were generally not used stereoscopically for forest applications or as bases for sampling frames until the 1950s although field application of stereoscopic techniques often preceded formal documentation by ten to fifteen years.
