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. 2. 1.1 Land cover. Database (NLCD) land cover layer is one of several primary and supplementary layers in NLCD 2006. INTRODUCTION. The GLC2000 project uses the FAO Land Cover Classification System (LCCS). These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. nlcd 2016 was delivered earlier this year, tracking u.s. land cover change for 15 years, from 2001-2016. the database consists of many separate land cover products, with 19 of the products shown here more than 75% of the pattern has the characteristics of a given class from the nomenclature. Home / AERMET / Mapping Land Use / Land Cover Codes from NLCD1992 to NLCD2011 19 Sep 2018 If you do chose to use land use data from the USGS that is more recent than 1992 (NLCD for 2001, 2006, 2011, and 2016), be aware that the classification schema for the newer data is … 1.4 A priori and a posteriori systems. The conceptual basis. DEFINITIONS . This update to the Alaska National Land Cover Database (NLCD) 2016 replaces the files dated 20200213. 1.3 Hierarchical versus non-hierarchical systems. the national land cover data ase is the nation’s authoritative land cover database. Within the U.S., SoftWright has provided NLCD data since 2012, starting with NLCD 2006 then NLCD 2011 and now the just-released NLCD 2016. Figure 1. The CORINE Land Cover is a vector map with a scale of 1:100 000, a minimum cartographic unit (MCU) of 25 ha and a geometric accuracy better than 100m. Land Cover or Land Use data describes the artificial or naturally-occurring land features at a particular location, assigning one of a discrete set of classifications to each point. The National Land Cover Database (NLCD) serves as the For more information about NLCD 92 and its successor, NLCD 2001, visit the Multi-Resolution Land Characteristics Consortium. 1. 1.2 Classification and legend.

PART A - Land Cover Classification System: A Dichotomous, Modular-Hierarchical Approach Classification Concepts. The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released four National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, and 2011. The National Land Cover Database. Global land cover data. 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). Global Land Cover 2000. A LAND USE AND LAND COVER CLASSIFICATION SYSTEM FOR USE WITH REMOTE SENSOR DATA By JAMEs R. ANDERSON, ERNEST E. HARDY, JoHN T. RoAcH, and RICHARD E. WITMER ABSTRACT The framework of a national land use and land cover classification system is presented for use with remote sensor data. It maps homogeneous landscape patterns, i.e. NLCD 2006 is the most recent 30-meter, seamless, wall-to-wall land cover database for the conterminous United States. In this update the landcover footprint was extended along the northern coast to include the islands that were missed in previous versions, and several duplicate roads (offset by 1 or 2 pixels) were removed on the Aleutian Islands. The National Land Cover .
