Assessing the Accuracy of Satellite-Derived Land Cover Classification Using Historical Aerial Photography Digital Orthophoto Quadrangles, and Airborne Video Data

Abstract:As the rapidly growing archives of satellite remote sensing imagery now span decades'worth of data, there is increasing interest in the study of long-term regional land cover change across multiple image dates. In most cases, however, temporally coincident ground sampled data are not available for accuracy assessment of the image-derived land cover classes, and other data and methods must be employed. The feasibility of utilizing historical aerial photography, digital orthophoto quadrangle (DOQ) images, and high-resolution airborne color video data to
determine the accuracy of satellite derived land cover maps was investigated for a southwestern U.S. watershed. Satellite imagery included Landsat Multi-Spectral Scanner (MSS) and Landsat Thematic Mapper (TM) data acquired over an approximately 25-year period.

This paper summarizes the results of three methods used to assess overall and individual
accuracy for ten land cover classes for the upper San Pedro River watershed, in southeastern Arizona and northeastern Sonora, Mexico. Land cover maps were produced from classifications of MSS imagery (5 June 1973, 10 June 1986, and 2 June 1992) and TM imagery (8 June 1997). The MSS imagery was projected to Universal Transverse Mercator ground coordinates with a pixel size of 60 meters; the 30 meter TM imagery was re-sampled and mapped with a pixel size of 60 meters to facilitate comparison.
