The IceBridge L1B Thinned Flight Lines, Version 1 data set has been updated to include the 2018 Antarctic campaign, with data from 10 October through 17 November 2018 at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
This data set contains simplified, or thinned, flight lines from NASA Operation IceBridge Greenland, Arctic, Antarctic, and Alaska missions. The thinning was performed using a Python library called Shapely. The full resolution flight line data were collected as part of Operation IceBridge funded aircraft survey campaigns.
