Assoc. Director of the USGS, Kevin Gallagher spoke following the 3DEP stakeholder meeting on the value of USGS partnerships.

Sample graphic of airborne lidar data acquisition. Target area is illuminated by pulsed laser light in the aircraft, Differences in laser return times and wavelengths are then used to make digital 3D representations of the selected ground sections.

This Landsat 8 image of central Ethiopia, acquired January 1, 2014, uses the shortwave infrared, near infrared, and red spectral bands (bands 6,5,4) to emphasize vegetation and land cover. In this combination, healthy vegetation appears bright green.

ASTER Surface Reflectance (AST_07) data can be used to view complex landscapes like the Rio Grande River Valley in southern New Mexico. This Terra ASTER surface reflectance natural color composite shows differences in reflectance over forested hills, irrigated agriculture, and arid regions.

Neal Pastick – lead author of the study – investigating erosion along Alaska’s Arctic coastline near the village of Kaktovik. Permafrost-dominated coasts of Alaska have drastically changed as the result of coastal transgression and storm-surge flooding which can result in the loss of cultural sites and damage to infrastructure.  Photo by M.

Example of the Landsat 8 OLI/TIRS Collection 2 level-2 science products. Left: Landsat 8 level-2 surface reflectance image. Right: Landsat 8 level-2 surface temperature image. The data was acquired on May 3, 2013 (path 140 row 41).

Landsat 8’s first image captured the area where the Great Plains and Rocky Mountains meet in Colorado in March 2013. The natural-color image shows the coniferous forest of the mountains coming down to the dormant plains. Boulder, Colorado, sits in the middle of the image.
