NASA IceBridge Thinned Aircraft Flight Paths

NASA Operation IceBridge L1B Thinned Flight Lines V001 contains simplified flight track data from airborne survey campaigns over Greenland, the Arctic, Antarctica, and Alaska. The NSIDC_CPRD processed the original high-resolution flight lines using the Shapely Python library for thinning. This derived dataset was last updated in November 2018.

Use Cases

• Map survey coverage gaps by analyzing thinned flight line geometries over polar regions.
• Correlate flight path locations with corresponding IceBridge L1B Flight Reports data.
• Visualize mission operational areas using the geospatial flight line features.

Strengths

• Data covers four major polar and sub-polar regions: Greenland, Arctic, Antarctic, and Alaska.
• Derived from funded NASA Operation IceBridge aircraft campaigns, ensuring authoritative source data.

Limitations

• Dataset is temporally stale, with no updates since 2018.
• The thinning process reduces spatial resolution, losing precise flight path details.
