Landsat-7 Project: 15m Resolution Greenland Ice Sheet Mosaic, 1999-2002

A complete 15-meter resolution image mosaic of the Greenland ice sheet, derived from USGS Landsat 7 ETM+ and CSA RADARSAT-1 imagery collected between 1999 and 2002. This dataset, part of NASA's MEaSUREs program, includes additional spectral bands useful for analyzing surface properties like snow grain size and bedrock outcrops. The panchromatic band provides the highest-resolution view for resolving topographic features and crevasses.

Use Cases

• Map ice sheet topography and large crevasses based on the 15-meter panchromatic mosaic.
• Analyze surface properties like snow grain size and blue ice regions based on the provided spectral bands.
• Classify land ice and ocean boundaries based on the combined Landsat and SAR imagery mentioned in the description.

Strengths

• Provides a complete mosaic of the Greenland ice sheet at 15-meter resolution.
• Includes multi-spectral bands for surface property analysis, with data collected from 1999 to 2002.
• Part of NASA's authoritative MEaSUREs program for creating Earth system data records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and dataset size are unknown, which may limit suitability assessment.
