Abstract

The most important subject in quantitative geomorphology is increasing of SPATIAL RESOLUTION to increase the information in the digital elevation model (DEM). Different models have been used to improve the SPATIAL RESOLUTION. Among the different models, sub-pixel/pixel spatial attraction model as the newest model is very high accuracy. In the study area was used the sub-pixel/pixel spatial attraction model for the first time to improve the SPATIAL RESOLUTION DEM in the southern city of Darab (Qalatuyeh). The sub- pixel attraction models convert the pixel towards sub- pixels based on the fraction values in neighboring pixels that can be attracted only by central pixel. Based on this approach only a maximum of eight neighboring pixels can be selected for the attraction. In the model other pixels are supposed to be far from the central pixel to have any attraction. In this study by using sub- pixel attraction model the SPATIAL RESOLUTION of digital elevation models (DEM) was increased. The design of the algorithm is accomplished by using digital elevation model (DEM) with SPATIAL RESOLUTION of 30 m (Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER)) and 90 m (Shuttle Radar Topography Mission (SRTM)) in the north of Darab, Fars province, Iran…
