Document Summary
Land use- how people use the land. Both are important and are really inseparable: together, they are called lulc data. Land use/land cover data are typically derived by classifying raw satellite images. Most lulc data products are released several years after the remote sensing images were taken. Most lulc data are raster data (array of grids) This structure allows for creating summary tables for quantifying the areas of different land use types. Sometimes, lulc data are converted into vector data. Gap analysis program (gap) land cover data. Created by multi-resolution land characteristics (mrlc) consortium. Derived from the landsat thematic mapper satellite data. Datasets in 1992, 2001, 2006, 2011, 2016 (to be released); not available every year. Mrlc consortium: a group of federal agencies including. The national oceanic and atmospheric administration (noaa) These agencies have a need for a nationally consistent land cover dataset. They combined financial resources to develop nlcd based on landsat thematic.
