Public lands have a variety of visual values. It is necessary to systematically identify and evaluate these values to determine the appropriate level of management.

These three inventory factors are considered together using guidance from H-8410-1 Illustration 11, to derive a visual inventory class representing the relative value of the visual resource for every square foot of land inventoried. The detail of the inventory may vary. The inventory protocol may vary in such places as Alaska where resource character and land-use patterns are significantly different from the lower 48. <\/span><\/p><\/div><\/div>", "summary": "This Map Service displays units that were inventoried for the Visual Resource Inventory.\nPublic lands have a variety of visual values.
