LANDFIRE is a large interagency project designed to provide nationwide spatial data for fire management applications. As part of the effort, many 2000 vintage Landsat Thematic Mapper and Enhanced plus sets were used in conjunction with volume field information generate detailed vegetation type structure entire United States. In order keep these current relevant resource managers, there was strong need develop an approach updating products. We are using three different approaches purposes....
LANDFIRE (LF) National (2001) was the original product suite of program, which included Existing Vegetation Cover (EVC), Height (EVH), and Type (EVT). Subsequent refinements after feedback from data users resulted in updated products, referred to as LF 2001, that now served LANDFIRE’s baseline datasets are basis for all subsequent updates. These updates account disturbances vegetation transition changes may not represent current conditions. Therefore, 2016 initiated Remap prototype determine...
Two experiments were conducted outdoors to investigate how bottom brightness impacts the spectral response of a water column under varied suspended sediment concentrations. A white aluminum panel placed at tank was used as bright bottom, and flat-black liner served dark bottom. Sixteen levels from 25 400 mg litre -1 in each experiment. Spectral data collected using Spectron SE-590 spectroradiometer. The major findings include following: had greatest impact visible wavelengths; when...
Routine acquisition of Landsat 5 Thematic Mapper (TM) data was discontinued recently and 7 Enhanced Plus (ETM+) has an ongoing problem with the scan line corrector (SLC), thereby creating spatial gaps when covering images obtained during process. Since temporal discontinuities are now imminent, it is therefore important to investigate other potential satellite that can be used replace data. We thus cross-compared two near-simultaneous from TM Indian Remote Sensing (IRS)-P6 Advanced Wide...
LANDFIRE (LF) has been producing periodic spatially explicit vegetation change maps (i.e., LF disturbance products) across the entire United States since 1999 at a 30 m spatial resolution. These products include data produced by various fire programs, field-mapped and fuel treatment activity events) submissions from agencies, disturbances detected U.S. Geological Survey Earth Resources Observation Science (EROS)-based Remote Sensing of Landscape Change (RSLC) process. The RSLC process...
The U.S. Geological Survey EROS Data Center archives, processes, and disseminates Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) data products. ASTER instrument is one of five sensors onboard the Earth Observing System's Terra satellite launched December 18, 1999. collects broad spectral coverage with high spatial resolution at near infrared, shortwave thermal infrared wavelengths ground resolutions 15, 30, 90 meters, respectively. are used in many ways to understand...
