Southwest Region Mapping Zone Boundaries
 Figure 1. Forty-seven unit map zones. |
 Figure 2. Twenty-five unit map zones. |
As a coordinated multi-institution endeavor each state institution was responsible for various tasks which were divided geographically. The five-state region was divided into ecologically and spectrally similar mapping zones. Each mapping zone provided a functional working area for project management, data collection and modeling. Each state was responsible for the mapping zones roughly corresponding to their state jurisdiction. Mapping zones were created at two levels. At the first level, 47 mapping zones were created for the five-state region (figure 1). These were primarily used for collecting and organizing field training data. At the second level, 25 mapping zones were created for the five-state region (figure 2). These were used for land cover modeling and validation.
