Vegetation/Land Cover Mapping of the Middle Fork of the Feather River Watershed Using Landsat Digital Data
The objective of this study was to use Landsat digital data combined with U-2 color infrared photography of the scale 1:30,000 and 1:120,000 for vegetation mapping of a forested area in northern California. This area, known as the Middle Fork of the Feather River Watershed, covers approximately 780,000 ha. The approach involved geometric correction of Landsat digital data (based on 43 control points), selection of ten training sites (100 x 100 pixels each), unsupervised classification of training sites, supervised classification of the entire study area, and production of results. Two approaches for unsupervised classification were examined, and the best results were achieved when the training sites were classified independently. The results included statistical summaries and a color-coded map of vegetation and land cover for the study area. Based on this study, we concluded that Landsat data provided the investigators with a quick and cost-effective means of mapping this vast and diverse area. Forest Sci. 30:248-258.
