1, two thermal bands of TM image dated 11/09/1984 and high gain thermal band of ETM+ images dated 05/03/2005 for the study area were processed and manipulated to retrieve sea surface temperature in subsequent four points of time (Table 1).
To retrieve sea surface temperature directly from Landsat-5 TM TIR and Landsat-7 ETM+ TIR data according a methodology of two main steps.
The purpose of this study is to analyze the land use/land cover change detection occurred in the mountains of High Santo Domingo river basin, located in Merida State, Venezuela, research work was performed in the mountains of high Santo Domingo river basin, Merida State, Venezuela, by using multitemporal change analysis in ten land cover/land use types: rock outcrop; urban area; crop-cattle land, natural forests, forested land; shrubland, grassland, bare soil surfaces; freshwater bodies (lakes, rivers, ravines), and paramo, for two time-periods of 1979 to 2000, and 2000 to 2005; integrating digital image processing techniques, Geographic Information System (GIS), and LANDSAT TM and ETM+ imagery.
