High-Resolution Satellite Imagery of Barrow, Alaska from 2002

62 orthorectified QuickBird satellite image tiles and accessory GIS layers cover the Barrow, Alaska region. Data was acquired by DigitalGlobe on August 1-2, 2002 and is managed by the NSIDC. This dataset is specifically designed to support research on Arctic environmental change.

Use Cases

• Analyzing coastal erosion patterns using high-resolution 1:63,360-scale USGS DRG mosaics.
• Mapping changes in tundra surface features and vegetation with orthorectified QuickBird imagery.
• Creating study area basemaps using the provided ESRI Shapefile index maps for the 62 data tiles.
• Conducting multi-temporal comparisons of the Barrow B4 Quadrangle using the 1:250,000-scale geospatial layers.

Strengths

• Contains 62 discrete, orthorectified satellite image tiles for detailed analysis.
• Includes multiple accessory geospatial layers (DRG mosaics, index maps) at 1:250,000 and 1:63,360 scales.
• Provides FGDC-compliant metadata in text, HTML, and XML formats for standardized documentation.

Limitations

• Data is from a single, narrow acquisition window (August 1-2, 2002), limiting temporal analysis.
• Access is restricted to investigators with a specific NSF OPP award number.
• Conflicting 'last updated' metadata: one source lists 2002-08-02, another lists 2026-03 13.
