* Corresponding author. Abstract – Recent improvements in sensor capabilities have enabled fire characterization from satellites. Instantaneous intensities of active fires have been characterized by the Fire Radiative Power (FRP), while burn severity has been assessed from the evaluation of Normalized Burn Ratios (NBR) derived from preand post-fire multispectral imagery. MODIS on the Terra and ...

The applicability of a land surface temperature (LST)-evapotranspiration (ET) regression model to estimate ET fraction (ETrF) was tested in the temperate maritime climate of Central Ireland. In this study, the Mapping ET at high Resolution and with Internalized Calibration (METRIC) model was applied to calculate evapotranspiration from a mixed land cover area in Central Ireland. The ETrF values...

The hydrologic networks play a paramount significance in paddy rice cultivation. The aerial photographs and satellite images, the latter were acquired from the Multispectral Scanner (MSS), Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI) were utilized to extract the fundamental information about the natural rivers and manmade canals over the past for...

Overstory vegetation maps of species and canopy cover were developed from Landsat 7 Thematic Enhanced Thematic Mapper satellite imagery. Ecosystem Monitoring plot data, collected during the 1997-2001 field seasons, were used as training sites for the image classification. Sixty-two species classes and four canopy cover classes were mapped. The maps will be used to support a Joint Fire Science P...

The Statewide Landcover and Trees Study (SLATS) is currently in the process of mapping woody change across the State of Queensland for the era 1999 to 2001. SLATS covers such a large area that Landsat Thematic Mapper (TM) imagery was chosen as the most effective data for this purpose. Since 1995 the woody change in Queensland has been mapped every two years. The 1999 to 2001 change era is the f...

A fully automated method uses Landsat Thematic Mapper data to map snow cover in the Sierra Nevada and make quantitative estimates of the fractional snow-covered area within each pixel. We model winter and spring reference scenes as linear mixtures of image end member spectra to produce the response variables for tree-based regression and classification models. Decision trees identify cloud cove...

Spatial-temporal changes of land use and land cover in Luang Namtha Province in northern part of Laos was analyzed using Landsat TM (Thematic Mapper)/ETM+ (Enhanced Thematic Mapper) images from 1990 to 2010 since the opening of the Boten border adjacent to China. The results showed that: (1) “forest land—cultivated land—grassland” was the primary landscape structure. Woodland was the major land...
