what is land cover data

EROS did the preprocessing and atmospheric correction of the images and developed three clear, low cloud images for all areas of the United States. Regional distribution of land under permanent meadows and pastures and comparison with corresponding land … Gen. Tech. Studying Canada’s Land Cover from Space. The different types of land cover can be managed or used quite differently. Maps can help managers assess urban growth, model water quality issues, predict and assess impacts from floods and storm surges, track wetland losses and potential impacts from sea level rise, prioritize areas for conservation efforts, and compare land cover changes with effects in the environment or to connections in socioeconomic changes such as increasing population. Coastal managers use land cover data and maps to better understand the impacts of natural phenomena and human use of the landscape. Finally, the concepts of the Ecological Systems used to define the map legend are inherently variable with a range of physiognomic and phenological conditions possible in a single system. A variety of other dataset were used in all or some of the regions to help with the land cover classification process. Jimenez, S. Martinuzzi, G. Potts, M. Quinones, M. Solorzona, E. Ventosa. No data point selected. Río Piedras, PR: U.S. Department of Agriculture, Forest Service, International Institute of Tropical Forestry. The Corine databases and several of its programmes have been taken over by the EEA. The datasets were assembled by Inez Fung, Elaine Matthews, and associates during 1984-1991. It identifies 33 mainland land cover classes (35 classes once the offshore Chatham Islands are included). 1996, Pal and Mather 2003). The New Zealand Land Cover Database (LCDB) is a multi-temporal, thematic classification of New Zealand's land cover. This layer contains several land classifications from GeoBase 250K Land Cover, Circa 2000 - Vector. Our goal was to generate a detailed land cover product representing the 2011 timeframe. For example, after a timber harvest land cover has changed, but the land use of that area will not have changed if seedlings were planted or natural regeneration is occurring and it will continue to be used for timber production. << Back to Land Cover Data Overview: Data and Tools. Differences between the 2001 and 2011 GAP maps do not always represent on-the-ground changes in vegetation communities. 2013). After each analyst completed the update for a geoarea, a second individual reviewed the resulting land cover classification. These geoareas are aggregations of the 66 Multi-Resolution Land Characteristics Consortium (MLRC mapping zones that have been used by NLCD, GAP and LANDFIRE as mapping zones in their 2001 national mapping efforts (Homer et al. This occurred when single pixels or small groups of pixels were isolated with respect to physiognomy type and no neighborhood majority of candidate ecological systems occurred (e.g., an island of forest in a large patch of grassland). For example, pixels comprising a combination of 2001 GAP non-forest, 2011 NLCD deciduous forest, and no disturbance, the recoding would be driven by the neighborhood majority of candidate pixels for deciduous forest types in the geoarea. 2013. Each dataset contains 12 data layers, each of which provides consensus information on the prevalence of one land-cover class. Permalink. Based on the interpretation of satellite imagery, CLC provides national scale maps of landcover and landcover change on a six year basis for thirty nine countries in Europe. After completion of the 2001 land cover, biennial updates have been done using a disturbance database to identify areas of change. Land cover is defined as the (bio) physical cover at the surface of the earth surface including grass, trees, bare ground and water. 2003), while Puerto Rico and Hawaii’s map legend are based on island specific classification systems (Gon et al. http://earthzine.org/2013/09/15/landfire-2010-updated-data-to-support-wi.... Pal, M. and P. M. Mather, 2003. - Land Cover and Manning's n Data After importing the data, the land cover dataset is shown in RAS Mapper. The findings on land use come from the NRI data category "Land Cover/Use," which comprises mutually exclusive categories such as cropland, rangeland, forest land, other rural land, developed land, and water areas. When used in conjunction with protected areas data (PAD-US), terrestrial ecosystems data can be used to identify habitat types that may be under-protected so management activities can be adjusted. O… Published Dec 02, 2020. Volume 1: Land cover, vertebrate species distribution, and land stewardship. Click on a pin on the map to see more information. Creating cloud-free Landsat ETM+ data sets in tropical landscapes: cloud and cloud-shadow re-moval. The NRI uses this classification to account for every acre of non-Federal land within the Nation. I would start searching for land use data at the local Metropolitan Planning Organization or Council of Government(aka MPO & COGs).
