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...

The U.S. Geological Survey (USGS)’s Land Cover program has leveraged methodologies from legacy land cover projects - National Land Cover Database (NLCD) and Land Change Monitoring, Assessment, and Projection (LCMAP) - together with modern innovations in geospatial deep learning technologies to create the next generation of land cover and land change information. The product suite is...

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...
