The Imagery_FilmCameraMission records the boundaries of aerial photo missions conducted by the US Forest Service to acquire aerial photos to support various planning, monitoring and inventory efforts in support of the agency mission and public projects across the nation. A companion feature class, Imagery_FilmCameraPhotoCenter, describes the geographic location of photo centers and general characteristics of each aerial photo. The two feature classes can be joined on the field MISSION_ID. The relationship between the two feature classes is that one mission feature is related to many photo center point features. |
