This data set contains surface elevation data over parts of Greenland, measured by the NASA Land, Vegetation, and Ice Sensor (LVIS), an airborne lidar scanning laser altimeter. The data were collected as part of NASA Operation IceBridge funded campaigns.
Data Set ID:
ILVIS2
IceBridge LVIS L2 Geolocated Surface Elevation Product, Version 2
This is the most recent version of these data.
Version Summary:
The data for 2009 through 2015 are stored in Version 1 of this data set.
Version 2 of this data set contains more parameters than Version 1. In addition, some parameters were renamed or removed. Essentially, Version 2 comprises the following changes:
- LVIS_LFID is now called LFID.
- LONGITUDE_LOW, LATITUDE_LOW, and ELEVATION_LOW were renamed to GLON, GLAT, and ZG.
- LONGITUDE_HIGH, LATITUDE_HIGH, and ELEVATION_HIGH were renamed to HLON, HLAT, and ZH.
- LONGITUDE_CENTROID, LATITUDE_CENTROID, and ELEVATION_CENTROID were removed.
- TLON, TLAT, and ZT were added.
- RH10 through RH100 were added.
- AZIMUTH, INCIDENTANGLE, RANGE, and COMPLEXITY were added.
- CHANNEL_ZT, CHANNEL_ZG, and CHANNEL_RH were added.
