North Slope Alaska Lake Water Classification Inventory

Water classification images and lake attribute data for the North Slope of Alaska. The dataset contains 54 records derived from Landsat MSS landcover classifications, organized by USGS 1:250,000 scale quadrangles. It was produced by the USGS and last updated in 1984.

Use Cases

• Classify lakes into categories like shallow, turbid, deep, and ice based on Landsat MSS imagery.
• Analyze lake acre size distribution for each water class within a specific 1:250,000 quadrangle.
• Map lake center latitude/longitude coordinates onto 1:63,360 scale maps for field navigation.
• Assess lake depth attributes in relation to geographic location for resource planning.

Strengths

• Contains 54 records of lake attributes across multiple quadrangles.
• Spatial referencing uses a consistent 50-meter grid cell size.
• Data can be output to two standard map scales: 1:250,000 and 1:63,360.

Limitations

• Small sample size of 54 records limits statistical analysis.
• Data is temporally stale, last updated in 1984.
• Limited documentation is available for the dataset.
