IceBridge 2009, Antarctica

In Fall 2009, LVIS co-mounted on the NASA DC-8 aircraft along with other Icebridge Sensors performed dedicated high-altitude, flights in Antarctica, performing large area maping of the Antarctic Peninsula and Pine Island Glacier, and the first survey of the 86S ICESat orbit maximum (dubbed the "polehole"). Data are available in both Level1B and Level2 formats. The Level1b data files contain the geolocated laser waveform data for each laser footprint. The Level2 data files contain elevations of reflecting surfaces derived from the Level1b data.

Level 2 files are much smaller and more manageable. For those users not familiar with waveform lidar data, we recommend that you start with the Level2 files before moving to the Level1b files (e.g., for context or to apply different algorithms). The Level1B data are in HDF5 and the Level2 data are in ascii.
