Settlement and Agricultural Practices of Bemba Shifting Cultivators in Northern Zambia from Multi-temporal LANDSAT TM Images

AUTOMATING INTERPRETATION OF GEOLOGICAL STRUCTURES FROM LANDSAT TM MULTI-SPECTRAL IMAGES AND DEMs

In this study using the Idrisi software system, a methodology for jointly analyzing and interpreting multi-spectral images and DEMs for extracting structural-geology features is given. In analyzing and interpreting multi-spectral images for geological features, certain criteria are employed to acquire information about the geological structures of the land, such as topographic, geomorphologic, ...

Predicting species diversity in agricultural environments using Landsat TM imagery

synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...

Multi-temporal Classification of Asar Images in Agricultural Areas

Human activities strongly affect the environment and impact natural resources. To reduce the disadvantages, we have to monitor the human activities as well as the environment. Therefore demand on continuous and inexpensive methods for environmental monitoring is strongly increasing. In this research and development project, ENVISAT polarimetric SAR data are examined for their usefulness to envi...

Automated Detection and Removal of Clouds and Their Shadows from Landsat TM Images

In 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 into the composite image from multitemporal images. The cloud regions can be detected on the basis of t...
