different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...

Abstract: As long as the effective contributions of satellite images in the continuous monitoring of the wide area and long range of time period, Landsat TM and Landsat ETM+ satellite images are surveyed. After quantization and classification of the deviations between TM and ETM+ images based on approved thresholds such as gains and biases or offsets, a correlation analysis method for the compa...

* Corresponding author and present address: Bangladesh Space Research and Remote Sensing Organization (SPARRSO), Agargaon, Sher-E-Bangla Nagar, Dhaka-1207, Bangladesh Abstract – Recent global climate change is the consequence of many human activities; deforestation in the tropics is one of them. The research estimated the amount of carbon flux due to forest cover change by combining satellite i...

The use of Pseudoinvariant Areas (PIA) makes it possible to carry out a reasonably robust and automatic radiometric correction for long time series of remote sensing imagery, as shown in previous studies for large data sets of Landsat MSS, TM, and ETM+ imagery. In addition, they can be employed to obtain more coherence among remote sensing data from different sensors. The present work validates...

Determining the productivity of forest sites through various classification techniques is important for making appropriate forest management decisions. Forest sites were classified using direct and indirect (site index) and remote sensing (Landsat 7 ETM and Quickbird satellite image) methods. In the direct method, forest site classifications were assigned according to edafic (soil properties), ...

the main aim of the present study was to map of urmia lake water surface diminishing rates over a long-term period, and demonstrating the most recent surface of emerged salty alluvial plains. for this purpose, landsat tm, etm+ and oli imageries, observing from 1984 to 2015, were progressively processed to generate most of the thematic models in tempo-spatial context. all multi-date satellite da...
