Data

Data collected to facilitate research and development activities pertaining to Annual NLCD algorithm development used as a benchmark for algorithm improvement iterations. The primary goal of these preliminary data was to offer preliminary insight into algorithm performance and guidance for algorithm improvement through error analysis.

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...

Post-fire vegetation structure and fuel data are needed to understand how an area recovers over time. To address this need, data were collected within the perimeter of the 2000 Jasper Fire near Custer, SD, on 73 plots co-located with plots previously established by scientists to assess burn severity. Vegetation structure data were collected at these plots during two periods: July 11–17...

The Landscape Water Requirement Satisfaction Index (L-WRSI) is an extension of the well-established water requirement satisfaction index (WRSI), which is an indicator of crop performance based on the availability of water to the crop during a growing season, by including the entire landscape and not just crop growing regions. L-WRSI is created using components generated by the VegET...

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

The LANDFIRE 2023 Update (LF 2023) product suite represents the final step in the ongoing goal to move towards annual updates and reduced latency. LANDFIRE'S goal has been to release an annual update every year that represents one year, specifically the previous year. Similar to the LF 2022 Update, in LF 2023, disturbances from the previous year are represented in current year products...

Rangeland ecosystems provide critical wildlife habitat (e.g., greater sage grouse, pronghorn, black-footed ferret), forage for livestock, carbon sequestration, provision of water resources, and recreational opportunities. At the same time, rangelands are vulnerable to climate change, fire, and anthropogenic disturbances. The arid-semiarid climate in most rangelands fluctuates widely...

This preliminary product contains annual land cover, land use, and change process variables for reference data plots in a .csv table. The same information available in the.csv file is also provided in a .xlsx format. The LCMAP Preliminary Duplicate Attributes Collection for Reference Data includes the attributes collected from 30-meter by 30-meter plots across the conterminous United...

The water balance equivalence (WABE) method for reducing biases from remote sensing-derived evapotranspiration (RSET) products for large area applications is proposed and implemented across eight-digit hydrologic unit code (HUC8) basins in the conterminous United States (CONUS). These data support the findings of the WABE method that includes climatology (2002-2015 average) observed...

These datasets provide weekly differences of early estimates of 2024 fractional cover for exotic annual grass (EAG) that were released from April to late June. The EAG estimates were publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contained five fractional cover maps along with their corresponding confidence maps for: 1) a...

Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. The cheatgrass and medusahead phenology in the Snake River Plain (SRP) and Northern Basin and Range (NBR) based on 30m near seamless Harmonized Landsat and Sentinel-2 (HLS) Normalized Difference...
