Natural Resource Technical Report for the Landsat mosaic for the Arctic Network. Most of the mosaic was covered by Landsat imagery acquired during a three week period in late July and early August 2002. Radiometric normalization was performed to minimize atmospheric effects, resulting in a mosaic with consistent and physically based properties. Two calibration approaches were evaluated (1) calibration to a target Landsat image and (2) calibration to a surface reflectance. The final mosaic was calibrated to surface reflectance, which improves the ability to perform spectral analyses over the full extent of the mosaic, and provides a robust basis for change detection and other time series studies. In addition, a topographic normalization procedure was performed on the mosaic to reduce the topographic effects of sun and terrain angles on the imagery.
