Land cover data details Bureau of Land Management lands within five specific watersheds in Western Alaska. The dataset is organized by 7.5' or 15' quadrangles and was created by SCIOPS, with a last recorded update in December 1985. It focuses on extracting acreage statistics for watersheds in designated Areas of Critical Environmental Concern.
Use Cases
- Extract land cover acreages by watershed using the quadrangle-based organization.
- Analyze historical land cover patterns within the Norton Bay, Unalakleet, Holy Cross, Iditarod, and Sleetmute quadrangles.
- Map Bureau of Land Management lands designated as Areas of Critical Environmental Concern in Western Alaska.
Strengths
- Covers five specific 1:250,000 scale U.S. Geological Survey quadrangles in Western Alaska.
- Organized by standard 7.5' or 15' quadrangle units for spatial analysis.
Limitations
- Data is over 35 years old, with a last update in 1985, limiting current applicability.
- The specific row count, column names, and total geographic area covered are unknown.
