Google Earth, a software based on satellite’s images and database of navigation, gains features of high resolution, integrated images, quick update, convenience, simpleness and free cost. Practice of this software shows that it plays an important role in mapping, construction and river research. Based on the fundamental features of Google Earth, this passage makes an introduction to its applica...

In recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. The study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste o...

Topics covered: 1. Conceptual framework – agents of pattern formation. 2. Abiotic factors – geology, geomorphology, hydrology, soils. 3. Climatic factors – temperature, precipitation, solar radiation, meteorology. 4. Climate-landform effects on vegetation pattern, ecological flows, disturbance regimes and geomorphological processes. 5. Resource management implications – climate change scenarios...

demonstration of the geomorphological factors in setting the legal regime of the caspian seaintroduction:the caspian sea is the largest water basin which enclosed by land within eurasia continent. the caspian sea is unique in many reasons: the large deposits of oil and gas, valuable fishery resources; including 90% of the world’s stock of sturgeon, important transportation routes; connecting th...

The recognition and the study of several spatial phenomena strongly depends on the resolution at which the analysis is carried out. The availability of an efficient way to represent the same phenomena at different resolutions is therefore very important (from both a mathematical and a computational point of view). Wavelets, families of base functions generated by dilation and translation of a m...

This study analyzes multi-temporal LiDAR data of high accuracy and high resolution by installing a geomorphometric model for extracting landslides. First, two sets of LiDAR data were acquired for before and after a heavy rainfall event. The landslides which took place from 2005 to 2009 were classified automatically by satellite images, and subsequently the landslides were interpreted and edited...
