Aerial ice survey photos, map-corrected (IceBridge)

IceBridge DMS L3 Ames Stereo Pipeline Orthorectified Images V001
land NASA NSIDC_CPRD Level 3 GeoTIFFJPEG
In plain English

What it measures. Aerial photographs of ice and snow surfaces that have been geometrically corrected so each pixel sits in its true map location.

How it's made. Produced by processing raw stereo aerial photos from IceBridge camera flights together with airborne lidar elevation data, using NASA's Ames Stereo Pipeline software, aboard a range of aircraft.

How & where you'd use it. Used to map ice and snow surfaces accurately and, alongside companion elevation models, to study changes in polar regions.

Official description

This data set represents a collection of orthorectified images that were created using the NASA Ames Stereo Pipeline. The final images were obtained by processing stereo images from the IceBridge DMS L0 Raw Imagery data set, along with NASA's Land, Vegetation, and Ice Sensor (LVIS) and Airborne Topographic Mapper (ATM) lidar data from the IceBridge LVIS L2 Geolocated Surface Elevation Product and IceBridge ATM L1B Elevation and Return Strength data sets, respectively. The closely related data set IceBridge DMS L3 Ames Stereo Pipeline Photogrammetric DEM provides the corresponding digital elevation models (DEMs) in GeoTIFF format.
