Colville River Delta Land Cover Classifications from Landsat and Aerial Imagery

Colville River Delta Landcover Data contains land cover classifications for a region in northern Alaska. The data is organized by U.S. Geological Survey quadrangles and spatially referenced to 50-meter grid cells. It was produced by the USGS using Landsat MSS data, aerial photography, and the National Wetlands Inventory.

Use Cases

• Classify land cover types like wetlands, tundra, or water bodies using the derived classification labels on a 50-meter grid.
• Analyze spatial patterns of land cover across the Colville River delta region using the quadrangle-based organization.
• Integrate the land cover classifications with other geospatial layers by keying on the USGS quadrangle basis.
• Study historical land cover derived from the four Landsat MSS records and aerial photography sources.

Strengths

• Spatial data is referenced to a consistent 50-meter grid cell resolution.
• Classifications integrate multiple data sources: Landsat MSS, aerial photography, and the National Wetlands Inventory.
• Coverage spans a defined area from 70°15' N to 70°30' N and 150°15' W to 151°30' W.

Limitations

• The dataset explicitly contains no Digital Elevation Model (DEM) data.
• The exact number of land cover classes, row count, and total file size are unknown.
• Data structure is described as sequential, which may require specific handling for modern GIS tools.
