Effects of Digital Elevation Models (DEM) Spatial Resolution on Hydrological Simulation
Digital Elevation Model is one of the most important data for watershed modeling whit hydrological models that it has a significant impact on hydrological processes simulation. Several studies by the Soil and Water Assessment Tool (SWAT) as useful Tool have indicated that the simulation results of this model is very sensitive to the quality of topographic data. The aim of this study is evaluati...
متن کاملAssessment 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 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 کاملDigital Elevation Model (DEM) generation using airborne SAR interferometry (InSAR)
Information about the shape of the Earth’s surface is important in many applications as it helps users to visualize and analyze geographic problems accurately in 3D. This paper focuses on the InSAR technique of generating Digital Elevation Models (DEM) by using InSAR data acquired from an airborne platform. The data cover a study area of 4 km x 3 km located in Thetford Forest, East Anglia, Unit...
متن کاملDigital surface model extraction with high details using single high resolution satellite image and SRTM global DEM based on deep learning
The digital surface model (DSM) is an important product in the field of photogrammetry and remote sensing and has variety of applications in this field. Existed techniques require more than one image for DSM extraction and in this paper it is tried to investigate and analyze the probability of DSM extraction from a single satellite image. In this regard, an algorithm based on deep convolutional...
