Landsat 8 and Landsat 9 Earth imaging acquisitions are guided by their respective Long Term Acquisition Plan (LTAP), that has been established for each satellite observatory. The LTAP is structured around the Worldwide Reference System-2 (WRS-2) grid, which partitions Landsat swath imaging of the Earth into ~185 × 180 km scenes using a path/row notation. These WRS-2 scenes represent the...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between April 27 and May 2, 2023, at four sites (Fort Zachary Taylor Historic State Park, Bahia Honda State Park, Curry Hammond State Park, and Long Key State Park), in the Florida Keys using high accuracy surveying technologies. Wadded Global Navigation Satellite System (GNSS) points and single beam sonar...

Scientists and engineers from the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) Cal/Val Center of Excellence (ECCOE) collected in situ measurements using field spectrometers to support the validation of surface reflectance products derived from Earth observing remote sensing imagery. Data provided in this data release were collected during select...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between September 30th and October 9th, 2021 over a large stretch of the Potomac River in Maryland and West Virginia using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data that was collected...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between October 25th and 31st, 2020 at several sites in eastern Iowa using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topographic light detection and ranging (lidar) data that was collected between December 7th, 2019 and November 19th, 2020...

Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These...

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 48 unique Landsat 9 Collection 2 images. These images were selected at random from the Landsat 9 archive from various locations around the world. While these validation images were subjectively designed by a single analyst, they provide...

Surface Urban Heat Island (SUHI) extent, intensity, and hotspots data of land surface temperature (LST) are provided across 50 regions throughout the Continental U.S. The annual land surface temperature (LST) were derived from Landsat U.S. Analysis Ready Data (ARD). The time series land surface Temperature (LST) and land cover change products were used to produce SUHI intensity and...

This data represents samples of algae from Upper Klamath Lake Oregon, during the summer of 2016. Data were sampled from the lake using standard protocols and then shipped to the remote sensing laboratory at the National Institute of Standards and Technology (NIST) for analysis on the hyperspectral microscope at NIST.
