Tanner, C. GUIDE TO PRESELECTION OF TRAINING SAMPLES AND GROUND TRUTH COLLECTION. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-77/100.
Description:
This report was prepared to provide the novice data processing analyst and field personnel with the tools and basic concepts used in the processing of multispectral scanner data via an interactive or conventional processing system. Included in the guide is an explanation of the need for the collection of accurate/inexpensive 'ground truth' and brief descriptions of the various ecosystems that will be encountered in this study. Also, a detailed list of the actual parameters that should be included in a well-designed ground truth form are provided. Sampling schemes from Landsat and aircraft multispectral scanner data are also discussed at length along with procedures and recommendations for selecting training samples from photography for use in automatic data processing.
