Land cover change monitoring within the east central Louisiana study site: A case for large area surveys with LANDSAT multispectral scanner data

摘要: Results established for four digital procedures developed characterizing the radiometric changes between multidate LANDSAT spectral data sets into meaningful measures of land cover/use dynamics are documented. Each technique's performance was contrasted against digitized use change maps, which were produced from contemporaneous, retrospective aerophoto coverage, in a cell by comparison over one half degree area east central Louisiana as standard comparison. The techniques identify 10.5 to 13.0% loss forestland five year period; however, they differ more how accurately this amount is distributed, need ancillary ground truth, and usable information that extractable. All require some method digitally co-registering two sets. capable providing tabular statistics well map products. Two detecting identifying their locations. other two, addition this, provide qualify cover conditions at each end study interval.
