BLM Visual Resource Inventory (VRI) Inventory Classes, Preferred Alt.

This dataset constitutes the spatial boundaries for Visual Resource Inventory Class (CLASS) polygons and respective relative ratings (Class I, II, III, or IV) for visual resource values across the area being inventoried. These inventory classes represent the relative value of the visual resources. Classes I and II being the most valued, Class III representing a moderate value, and Class IV being of least value. BLM administered lands are placed into the inventory classes based on the overlay of three spatial data sets; visual appeal of a tract of land (scenic quality), the amount of public concern for scenic quality (visual sensitivity), and whether the tract of land is visible from travel routes or observation points (distance zones). This dataset is a compilation of these three measures which are recorded in the vri_sqru_poly (scenic quality), vri_slru_poly (sensitivity) and vri_vdz_poly (distance zone) datasets. The Visual Resource Inventory Classes are informational in nature, and do not constitute a management class. However, they do serve as a baseline of information from which the affected environment sections of all subsequent NEPA analysis should reference
