ABoVE 2017

In June-July 2017, the NASA LVIS Facility was deployed to sites in northern Canada and Alaska as part of NASA's Arctic-Boreal Vulnerability Experiment (ABoVE) 2017 airborne campaign. During the 4 week deployment of LVIS-F, a total of 15 flights were flown over diverse science targets based out of multiple airports in Canada and Alaska. 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 canopy top and ground elevations and relative heights 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.


Further details on the Level1B and Level2 data structures can be found in the following document: LVIS_GabonAfriSAR_data_release.pdf
