A Comparison of AVIRIS and Synthetic Landsat Data for Land Use Classification at the Urban Fringe
Abstract
In this study I tested whether AVIRIS data allowed for improved classification over synthetic Landsat TM data for a location on the urban-rural fringe of Colorado. After processing the AVIRIS image and creating a synthetic Landsat image, I used standard classification and post-classification procedures to compare the data sources for land use mapping. I found that, for this location, AVIRIS holds modest but real advantages over Landsat for the classification of heterogeneous and vegetated land uses. Furthermore, this advantage comes almost entirely from the high spectral resolution of the sensor rather than the high radiometric resolution.
