PROCEDURES FOR GATHERING TRUTH INFORMATION FOR A SUPERVISED APPROACH TO A COMPUTER IMPLEMENTED LAND COVER CLASSIFICATION OF LANDSAT ACQUIRED MULTISPECTRAL SCANNER DATA

摘要

Procedures for gathering ground truth information for a supervised approach to a computer-implemented land cover classification of Landsat-acquired multispectral scanner data are provided in a step-by-step manner. Criteria for determining size, number, uniformity, and predominant land cover of training sample sites are established. Suggestions are made for the organization and orientation of field team personnel, the procedures used in the field, and the format of the forms to be used. Estimates are made of the probable expenditures in time and costs. Examples of ground truth forms and definitions and criteria of major land cover categories are provided in appendixes.
