Digital Aerial Imaging Quality Assurance


Test Site Over EROS

The U.S. Geological Survey (USGS) has provided analog film camera calibration to the mapping community since the early 1970s. As digital camera technology continues to advance and become prevalent, techniques for characterizing and calibrating digital systems and validating the resulting products are required.

In 1999, the American Society of Photogrammetry and Remote Sensing (ASPRS) formed a panel of experts from industry, academia, and government to review calibration methods and related concerns created by the advancement of digital aerial sensors. In 2000, the panel recommended the USGS address digital aerial imaging issues through research and standards development. Working with industry and academia, the USGS established a program of research and investigations into the capabilities of digital aerial sensors.

To represent the major Federal purchasers and users of aerial imagery, the USGS formed the Inter-Agency Digital Imagery Working Group (IADIWG). The working group has provided input for the development of the USGS Plan for the Quality Assurance of Digital Aerial Imagery. This effort consists of four main parts:
