For NLCD 2011, there are 5 primary data products: 1) NLCD 2011 Land Cover; 2) NLCD 2006/2011 Land Cover Change Pixels labeled with the 2011 land cover class; 3) NLCD 2011 Percent Developed Imperviousness; 4) NLCD 2006/2011 Percent Developed Imperviousness Change Pixels; and 5) NLCD 2011 Tree Canopy Cover provided by an MRLC partner - the U.S.D.A. 1992 data are primarily based on unsupervised classification of Landsat data, while the rest of the images rely on the imperviousness data layer for the urban classes and on a decision-tree classification for the rest. Percent Impervious Area. Legend. NLCD 2011 Percent Developed Imperviousness. For NLCD 2011, there are 5 primary data products: 1) NLCD 2011 Land Cover; 2) NLCD 2006/2011 Land Cover Change Pixels labeled with the 2011 land cover class; 3) NLCD 2011 Percent Developed Imperviousness; 4) NLCD 2006/2011 Percent Developed Imperviousness Change Pixels; and 5) NLCD 2011 Tree Canopy Cover provided by an MRLC partner - the U.S.D.A. NLCD 2011 Percent Developed Imperviousness and Percent Developed Imperviousness Change Analysis: Because the four NLCD developed classes are derived from a percent imperviousness mapping product, an overview of steps required to update the NLCD 2001 imperviousness to reflect urban growth captured in 2006 era Landsat imagery is provided here (Xian et al., 2010). To examine results in a hydrologic application, the BELLR estimated BIAs were tested using two different types of hydrologic models to compare BELLR results with results using the National Land Cover Database (NLCD) 2011 Percent Developed Imperviousness data. NLCD imperviousness products represent urban impervious surfaces as a percentage of developed surface over every 30-meter pixel in the United States. (1) U.S. Geological Survey developed an impervious surface estimate (NLCD Percent Developed Imperviousness) raster dataset based on the NLCD land cover data from year 2011. The data in NLCD 2011 are completely integrated with NLCD 2001 (2011 Edition, amended 2014) and NLCD 2006 (2011 Edition, amended 2014). NLCD 2006 Percent Developed Imperviousness. Average values of the NLCD developed imperviousness were quantified per land use class through spatial analysis. Description. This dataset represents percent developed imperviousness clipped to the Northeast. This update represents a seamless assembly of updated NLCD 2001 Percent Developed Imperviousness for all 66 MRLC mapping zones.

(dataset) Multi-Resolution Land Characteristics Consortium (MRLC). 2011 NLCD. CSCI is responsive to stress 45 . When all four neural network prediction images agreed with a change of 50% or more from the 2011 NLCD map, the average of those four images replaced that pixel from the 2011 imperviousness map. A subspecies of Allen’s Hummingbird (Selasphorus sasin sedentarius) expanded its population in urban Southern California (Clark 2017). The NLCD 2006 Percent Developed Imperviousness (2011 Edition)and the NLCD 2011 Percent Developed Imperviousness were compared in a model to provide the user community with a layer that depicts imperviousness change between 2006 and 2011. Questions about the NLCD 2001 Percent Developed Imperviousness 2011 Edition can be directed to the NLCD 2001 land cover mapping team at the National Center, EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

This EnviroAtlas national map estimates the percentage of land within each 12-digit hydrologic unit (HUC) that is classified as impervious by the 2011 National Land Cover Dataset (NLCD) Percent Developed Impervious Surface Layer. (2011) Harmonization of land-use s cenarios for the period . light pink linear features with darker pink and red clusters represent impervious surface data from the National Land Cover Database 2011 Percent Developed Imperviousness dataset (NLCD11). The full dataset is divided into 25 zones, which can all be found in the NLCD 2006 gallery. NLCD provides %IC for each 30 m-x-30 m pixel in 1% increments from 0% to 100% for NLCD 2001 (Homer et al., 2007), NLCD 2006 (Fry et al., 2011), NLCD 2011 (Homer et al., 2015), and change across the three eras (Xian et al., 2011). Forest Service Remote Sensing … Click to view full size image. Imperviousness threshold values used to derive the NLCD developed classes are: (1) developed open space (imperviousness < 20%), (2) low-intensity developed (imperviousness from 20 - 49%), (3) medium intensity developed (imperviousness from 50 -79%), and (4) … Forest Service Remote … The NLCD 2006 Percent Developed Imperviousness (2011 Edition) and the NLCD 2011 Percent Developed Imperviousness were compared in a model to provide the user community with a layer that depicts imperviousness change between 2006 and 2011. So, for example, the site QR6 @ Sand Br (TNC) has a dark pink dot over an orange circle, so it was sampled for a total of between 16 and 20 years, including Similarly, Anna’s Hummingbird (Calypte anna) and Black-chinned Hummingbird ... transitions out of “developed ... Chini LP, Frolking S, et al. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016. For NLCD 2006 (2011 Edition), there are 4 primary data products: 1) NLCD 2006 Land Cover (2011 Edition); 2) NLCD 2001/2006 Land Cover Change Pixels (2011 Edition) labeled with the 2006 land cover class; 3) NLCD 2006 Percent Developed Imperviousness (2011 Edition), and 4) NLCD 2001/2006 Percent Developed Imperviousness Change (2011 Edition). Description. Compared to the ground truth, the method used showed significant promise, with an R2 of 0.73 and RMSE of 0.123. Data downloads. Zone 5 (covering parts of California and Nevada) of the contiguous U.S. percent developed imperviousness dataset from NLCD 2006, released 2/16/2011. NLCD (the National Land Cover Database) is a 30-m Landsat-based land cover database spanning 8 epochs (1992, 2001, 2004, 2006, 2008, 2011, 2013 and 2016). some and detrimental to others (Faeth et al. NLCD is generated in cooperation with the Multi-Resolution Land Characteristics Consortium a partnership of Federal agencies working together to produce current, nationally consistent, land cover products for all 50 states and Puerto Rico.NLCD is used for thousands of applications that require information on landcover location or where it is changing. The NLCD 2006 Percent Developed Imperviousness (2011 Edition)and the NLCD 2011 Percent Developed Imperviousness were compared in a model to provide the user community with a layer that depicts imperviousness change between 2006 and 2011. For NLCD 2006 (2011 Edition), there are 4 primary data products: 1) NLCD 2006 Land Cover (2011 Edition); 2) NLCD 2001/2006 Land Cover Change Pixels (2011 Edition) labeled with the 2006 land cover class; 3) NLCD 2006 Percent Developed Imperviousness (2011 Edition), and 4) NLCD 2001/2006 Percent Developed Imperviousness Change (2011 Edition). Generation of NLCD 2006 data products helped to identify some update issues in the NLCD 2001 land cover and percent developed imperviousness data products. NLCD imperviousness products represent urban impervious surfaces as a percentage of developed surface over every 30-meter pixel in the United States. NLCD 2011 is the most up-to-date iteration of the National Land Cover Database, the definitive Landsat-based, 30-meter resolution land cover database for the Nation. Percentage IC has been a database element of NLCD since 2001. Forest Service Remote Sensing … This NLCD product is the version dated October 10, 2014. These issues were evaluated and corrected, necessitating a reissue of NLCD 2001 data products (NLCD 2001 Version 2.0) as part of the NLCD 2006 release. Click to view full size image.
