Columbia Glacier Elevation Models from Aerial Flights, 2002-2010

Digital elevation models derived from annual aerial stereographic flights over the Columbia Glacier. The dataset covers flights from 2002 to 2010 and was compiled by the organization SCIOPS. Data products are stored in TAR file format, containing scans of large-format diapositives and derived outputs.

Use Cases

• Analyze glacier surface elevation changes over time using the derived DEMs from 2002-2010.
• Correlate flight-derived elevation data with other glacier inventory metrics from the Aerial Inventory.
• Process the scanned large-format diapositives to generate new digital elevation products.

Strengths

• Multi-year temporal coverage from 2002 to 2010.
• Data derived from large-format aerial diapositives, a high-resolution source.

Limitations

• Data is temporally stale, with the last update recorded in June 2010.
• Specific row counts, file sizes, and geographic extent beyond the glacier are unknown.
