No new imperviousness products for Alaska, Hawaii and Puerto Rico are available from NLCD 2016. NLCD from 2001 to 2016 (Animation) The 2001 National Land Cover Database (NLCD) tree and impervious cover maps provide an opportunity to extract basic land-cover information helpful for natural resource assessments. 2001 NLCD Rogue Agricultural Lands National Land Cover Database 2001 (NLCD2001) is a 16-class (additional four classes in Alaska only) land cover classification scheme that has been applied consistently across all 50 United States and Puerto Rico at a spatial resolution of 30 meters. Canadian Journal of Remote Sensing, Vol. See Legend. We compared the National Land Cover Database (NLCD) 2001 land cover, impervious, and canopy data products to land cover data derived from 0.6-m resolution three-band digital imagery and ancillary data. N/A N/A Collin Homer Jon Dewitz Limin Yang 201505 Completion of the 2011 National Land Cover Database for the Conterminous United States - Representing a Decade of Land Cover Change Information 30 meter raster, with cells classified into one of 21 land cover classes. - A new “impervious descriptor” data layer for each of those years to show the footprint of wind energy in the U.S., - Improved accuracy through the integration of decades of forest regrowth data from LANDFIRE and Landsat Analysis Ready Data (ARD) tiles generated for the USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative. Details Image Dimensions: 7106 x 5131 Date Taken: 2016 (approx.) Location Taken: US Explore More No new imperviousness products for Alaska, Hawaii and Puerto Rico are available from NLCD 2016. Since vector layers are highly challenging for large-scale analysis, Heris et al. NCLD 2019 is scheduled for release during the winter of 2020, marking the most rapid turnaround for a national-scale land cover dataset in the project’s history. The next edition of the National Land Cover Database (NLCD) will appear more quickly than previous editions, offer accuracy comparable to NLCD 2016, and include previously-unreleased historical information on imperious urban surfaces. New products for the western CONUS are a set of shrubland maps for 2016, which estimate the “We’re using new and improved methods to decrease the latency between releases.”. For example, building coverage ratio increased as a power function of the percentage of the impervious surface area as estimated in NLCD (Fig. The current Landsat ARD tiles used for LCMAP’s work now serve as a starting point for NLCD 2019’s compositing work. The National Land Cover Databse (NLCD) is working to incorporate wind turbine data, as shown in this screenshot, into its impervious surface products for NLCD 2019. NLCD 2016 updates all previously released versions of impervious products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011) along with a new date of impervious surface for 2016. With the 2016 release, the intended snapshot interval is 2-3 years, beginning with 2001. 2, a), and … New for NLCD 2016 is an impervious surface descriptor layer. NLCD data layers are not produced at an annual time step, but land cover is produced at a two- … Previous estimates that compared NLCD tree An approach for mapping large-area impervious surfaces: Synergistic use of Landsat 7 ETM+ and high spatial resolution imagery. This descriptor layer identifies types of roads, core urban areas, and energy production sites for each impervious pixel to allow deeper analysis of developed features. Figure 3: Example of the subpixel impervious surface product (left) and the impervious surface descriptor (right) available with the NLCD 2016 edition. The three largest countries in North America share trade, climate and culture in a host of broad and specific ways. For additional information regarding creation of NLCD percent developed imperviousness products: Xian, G., Homer, C., Dewitz, J., Fry, J., Hossain, N., and Wickham, J., 2011. 2, pp.230-240. The initial runoff from paved surfaces can reach extremely high temperatures “Being able to kick out a national scale map within a year is pretty impressive.”. The National Land Cover Database (NLCD) 2016 product suite was recently released for bulk download on the Multi-Resolution Land Characteristics Consortium (MRLC) website. NLCD provides additional geospatial information for the country and involves partner products such as tree canopy, urban imperviousness, and western U.S. shrub and grassland area at varying periodicities. New for NLCD 2016 is an impervious surface descriptor layer. Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, Eyes on Earth Episode 3 - National Land Cover Database, Earth Resources Observation and Science (EROS) Center, Earth Resources Observation and Science Center, New Land Cover Maps Depict 15 Years of Alaska Change, EROS contributes to New Land Cover Maps for U.S., Canada, Mexico, New NLCD products to be folded into Esri software, Earth Engine, Multi-Resolution Land Characteristics Consortium, New Land Cover Maps Depict 15 Years of Change across America. An alternative approach to this analysis would have been to analyze the NLCD “Change in Developed Impervious Surface Area from 2001–2006” product published by the Multi-Resolution Land Characteristics Consortium (Xian et). NLCD is currently working on an update for 2019 land cover conditions. A new set of land cover maps for the U.S., Canada, and Mexico highlights a specific, long-standing scientific collaboration designed to benefit each nation. Urban infrastructure efficiently routes runoff over hot impervious surfaces and through storm drains directly into streams and can lead to rapid, dramatic increases in temperature. Users of ArcGIS and Google’s Earth Engine, however, will soon have web access to the data directly through their preferred platform. The highlights for NCLD users in the 2019 products are the accuracy improvements through collaboration with other EROS-based land cover projects and the expansive upgrades to impervious surface products through the integration of new data sources, Dewitz said. We used National Land Cover Data 92 (NLCD 92), vector impervious surface data, and raster GIS overlay methods to derive impervious surface coefficients per … 77(8): 758-762. Imperviousness data from the National Land Cover Dataset (NLCD). Today, the U.S. Geological Survey (USGS) released the latest edition of the National Land Cover Database (NLCD) for the U.S. – the most comprehensive land cover database that the USGS has ever produced. 2. 29, No. USFS Oklahoma-based tree canopy cover and 2011 NLCD developed impervious surface layers and site point locations (Google Earth) were added in … • New Impervious Descriptor layer that identifies types of roads, core urban areas, and energy production sites for each impervious pixel NLCD 2016 Percent Tree Canopy product • Produced by … Photogrammetric Engineering and Remote Sensing, Vol. The change of impervious surface area between 2001 and 2006 in the conterminous United States. impervious_descriptor Defines which impervious layer pixels are roads and provides the best fit description for impervious pixels that are not roads. New for NLCD 2016 is an impervious surface descriptor layer. He took on a leadership role for NLCD again in 2020, and he’s been impressed by the production team’s speed and efficiency as it endeavors to update one of the most widely-used EROS datasets. Nationwide coverage, including Alaska, Hawaii, and Puerto Rico. NCLD 2019, in the works for late 2020 or early 2021, will offer the same information for 2019, but will also include several significant improvements.
