The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at the native 30-m spatial resolution of the Landsat Thematic Mapper (TM). Dwarf scrub: Alaska only areas dominated by shrubs less than 20 centimeters tall with shrub canopy typically greater than 20% of total vegetation. NLCD 2011 is based primarily on a decision-tree classification of circa 2011 Landsat satellite data. Export to . Ecological Potential rangeland fractional cover data products represent the potential cover given the most productive, least disturbed, portion of the 1985-2020 Landsat archive. But now Land Change Monitoring, Assessment, and Projection (LCMAP) Collection 1 science products provide unprecedented monitoring of past changes occurring in land cover and condition across the conterminous U.S. over more than 30 years at an annual timestep. We report an automated method of mapping rangeland fractional component cover over a large po, Locations of and proportional abundance of non-native and synanthropic passerines were extracted from Breeding Bird Survey (BBS) data from 2010-2012. 2018 NavStreets Street Data. This collaboration provides a first of its kind rangeland monitoring framework with multiple yearly fractional components spanning 1985 to 2017. When using any imagery, data products, or information accessed from USGS or NASAs LP DAAC systems, we do ask that proper credit be given. Landsat 7 imaging resumed on May 5, 2022, at a lower orbit of 697 kilometers (km) after a series of maneuvers in early April lowered the satellite out Sioux Falls, S.D. Well pads. Spatial Reference Information: Universal Transverse Mercator, North American Datum 1983. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nations land resources, the USGS has designed a new generation of NLCD products named NLCD 2019. (Read More), Currently available trends statistics are for the 1985-2021 time-series. Please note these new Revised (071520) rangeland products will differ from the first generation of circa 2016 fractional cover maps, a more aggressive masking of tree canopy cover was applied to each rangeland component. Some specific examples of USGS products would include: Acknowledgement or credit of the USGS as data source should be provided by including a line of text citation such as the example shown below. Bloomberg. IKONOS. Land Cover Atlas Online viewer makes it easier to explore land cover change data. In this episode, we learn about the latest land cover release from EROS. NLCD 2019 offers 8 integrated epochs of land cover for years 2001, 2004, 2006, 2008, 2011, 2013, 2016, and 2019. The NLCD 2019 land cover product uses Landsat composites derived from Landsat Analysis Ready Data (ARD) and a complex, multi-step modeling process to provide an update of U.S. land cover based on 2019 imagery. The two main objectives were assessment of agreement between map and reference labels for the three, single-date NLCD land cover products at Level II and Level I, Release of NLCD 2006 provides the first wall-to-wall land-cover change database for the conterminous United States from Landsat Thematic Mapper (TM) data. Some datasets available through the USGS EROS archives are hosted and distributed based on partnership or other agreement with an external (non-USGS) source. The USGS EROS Center supports delivery and access systems for a variety of NASAs LP DAAC science datasets. Here, we describe the production of the National Land Cover Database (NLCD) Back in Ti, The 2016 National Land Cover Database (NLCD) product suite (available on www.mrlc.gov), includes Landsat-based, 30 m resolution products over the conterminous (CONUS) United States (U.S.) for land cover, urban imperviousness, and tree, shrub, herbaceous and bare ground fractional percentages. The latest edition of the National Land Cover Database (NLCD 2016) for Alaska is now publicly available.

NLCD 1992, NLCD 2001, NLCD 2006, and NLCD 2011 are National Land Cover Database classification schemes based primarily on Landsat data along with ancillary data sources, such as topography, census and agricultural statistics, soil characteristics, wetlands, and other land cover maps. Pixels were derived from the Earth Engine is free to use for research, education, and nonprofit use. database spanning 8 epochs A lock () or https:// means youve safely connected to the .gov website. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. See included spatial metadata for more details. Systematically aligned over time, the database provides the ability to understand both current and historical land cover and land cover change, and enables monitoring and trend assessments.

These areas are not subject to intensive management such as tilling, but can be utilized for grazing. Impervious surfaces account for 20% to 49% percent of total cover. The NLCD 2019 design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database from 2001 to 2019 at 23-year intervals.
