Potentials and constraints of soil salinity studies in two different conditions of Iran

The aim of this project was to determine the accuracy of using simple digital image processing techniques to map riverine water bodies with Landsat 5 TM data. This paper quantifies the classification accuracy of single band density slicing of Landsat 5 TM data to delineate water bodies on riverine

method, which used spatial information to guide the decomposition process; on artificial Landsat-TM images this method proved to be far more accurate than techniques based on classification or pixel-based decomposition. To investigate whether data-driven decomposition also results in an improved area

combination of edge-line detection Canny algorithm was used, a grid operator designed for the analysis of potential field data was applied to a digital elevation model for the detection of lineaments using Landsat TM and ASTERGDEM images. At different orientations, by simulating topographic illumination under

The main purpose of this study was to investigate the image value gradient problem which was observed in Landsat TM images during the production of WAGIS mosaic (Toivonen et al., 2002) currently present on the Internet-based Western Amazon Geographic Information Service (www

This paper summarises the use of digital remotely sensed data for Quaternary deposits mapping in central Sweden. Landsat TM scene of the beginning of May 1985 was applied. Only six groups of quaternary deposits were distinguished. The classification accuracy of the resultant map was about 50

this paper, a scheme to remove clouds and their shadows from remotely sensed images of Landsat TM over land has been proposed. The scheme uses the image fusion technique to automatically recognize and remove contamination of clouds and their shadows, and integrate complementary information

Landsat-5 Thematic Mapper (TM) has been imaging the Earth since March 1984 and Landsat-7 Enhanced Thematic Mapper Plus (ETM+) was added to the series of Landsat instruments in April 1999. The stability and calibration of the ETM+ has been monitored extensively since launch. Though not monitored

This paper describes a method for cloud cover assessment using computerbased analysis of multi-band Landsat images. The objective is to accurately determine the percentage of cloud cover in an efficient manner. The “correct ” value is determined by an expert’s visual assessment. Acceptable error
