Save so as not to lose. developed to meet the needs of Federal and State agencies for an up-to-date Then the classification of land use and land cover can proceed without the unwanted radiometric anomalies of terrain aspect. I know we can all write essays ourselves. 0000006510 00000 n As of this date, Scribd will manage your SlideShare account and any content you may have on SlideShare, and Scribd's General Terms of Use and Privacy Policy will apply. uniform in categorization at the more generalized first and second levels and Topics run the gamut from tracking urban development to studying forest harvest cycles or forest pests and disease, from estimating hurricane damage to mapping wildfire scars, from monitoring agricultural patterns to ecosystem health. The urban, agriculture, and water classes were taken directly from the NLCD 2011 … NLCD was launched in the 1990s and the earliest published dataset characterized land cover for 1992. Utilizing modern solid state technology, there is no reason why such stereo data cannot be acquired simultaneously with the multispectral response, thus simplifying the overall problem of land use and land cover classification. National Land Cover Database land cover for the conterminous United States, represented as 16 land cover classes. In combination with other LCMAP products such as spectral stability (SCSTAB) or change magnitude (SCMAG), the suite of annual LCMAP products is a powerful tool to assess change at finer time scales, or more subtle changes in landscape condition that may not be represented in the thematic land cover product (LCPRI). However, LCMAP is just the most recent effort providing land cover information for the United States at a 30-m spatial resolution using a Landsat time series. 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. Revision of the land use classification system as presented in U.S. Geological Survey Circular 671 was undertaken in order to Below are publications associated with this project. intentionally left open-ended so that Federal, regional, State, and local presented for use with remote sensor data. The USGS, in collaboration with the Bureau of Land Management, has … browser may not display or print as intended. Classification Scheme. This will definitely make your life more easier, Hi there! It is 0000021610 00000 n 0000002464 00000 n Understanding current and future user needs is crucial...

Absolute elevation governs various types of vegetative growth as does the degree and direction of slope. It was ridiculous. (click animation for details). The LCMAP change detection method relies on a harmonic modeling process based on a long time series of Landsat observations starting with 1982 (from TM, ETM+, and OLI instruments) that has been reconditioned into Landsat Analysis Ready Data (ARD). Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. EROS is central to the creation of the National Land Cover Database (NLCD), which is updated every five years and stands as the definitive land cover database for the United States. Share sensitive information only on official, secure websites. Accordingly, … Sensing For Planning. The primary source data were bands 3, 4, 5, and 7 (visible red, near-infrared, mid-infrared, and thermal infrared) of cloud-free Landsat TM scenes acquired during the spring and fall (when trees are mostly bare of leaves) of 1992. NLCD 2006 quantifies land cover change for the conterminous U.S. between the years 2001 to 2006. Validation at stage 2 has been achieved for MODIS land cover products. One annual product in the LCMAP suite, the timing of spectral change (SCTIME) provides an estimate of the day of year when change was detected. In choosing between LCMAP or NLCD land cover products, researchers should consider the different thematic detail of the land cover legends, the level of accuracy required, the period of record needed, and the temporal repeat or frequency of coverage. Impervious surface layers (currently provided at nominal 5-year intervals) provide information valuable for hydrologic applications, for example. While the combination of LCMAP and NLCD provides a comprehensive land change database covering the conterminous U.S., we are looking to the future with a focus on 1) reducing latency in delivery of data, providing information at “the speed of decision,” 2) improving efficiencies, utilizing state-of-the-art technologies to improve reproducibility, increase accuracy, and develop tighter synergies between the LCMAP and NLCD projects, and 3) expanding the breadth of land change information provided by USGS, with a focus on designing new operational products that are best able to address broad stakeholder and partner needs.
