Assessment Effect of the Spatial Resolution of Digital Elevation Model on Daily Discharge Estimation of Arazkuseh Watershed Using SWAT Model
The spatial quality of the Digital Elevation Model (DEM) has a great effect on the Soil and Water Assessment Tool (SWAT) semi-distributed model. The purpose of this study was to evaluate the effect of spatial accuracy of three DEMs with spatial resolutions of 10, 50 and 200 m on the results of daily discharge simulation in the Arazkuseh subwatershed located in Gorganroud watershed, Golestan pro...
متن کاملgenerating a vegetation map in mountainous region of sabzkouh using a digital elevation model
the analysis of the relationship between spatial distribution of environmental factors andvegetation types is crucial for understanding mountainous ecosystems. in this research agis based approach was used to produce a vegetation map for sabzkouh protected area inthe chaharmahal-va-bakhtiari province. to identify environmental parameters affecting thevegetation cover, 6 primary and secondary en...
متن کاملAccuracy of Digital Elevation Model According to Spatial Resolution
There are many kinds of DEM (Digital Elevation Model) generation methods such as a stereomatching from aerial photograph or satellite image, an interferometry from SAR data and an interpolation of topographic maps. On the other hand, we can use some accomplished DEMs. For example, NGDC NOAA offers global land one-km base elevation (GLOBE). And USGS offers Digital Chart of the World that has ele...
متن کاملEffects of Digital Elevation Model (DEM) Spatial Resolution on the Recognition of Physiography Characteristics of the Basin )A Case Study of Shahrchai Watershed)
In recent years with developing geographic information systems tools, modeling and simulating methods has been developed quickly. Availability of accurate base maps is the basis of the cell sizes determination and preparing digital hydrologic models. Removing errors and minimizing of uncertainty factors in the digital models play the main role in improving the accuracy of the maps. The main pur...
متن کاملa 10-bit 50-ms/s parallel successive-approximation analog-to-digital converter
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
