Drought Analysis of Alvand Boundary River Using Remote Sensing Data
Extended abstract 1- Introduction The study of the behavior of rivers in the arid and dry areas is one of the most important tasks in the country. Because the area has increased the effects of drought due to the sensitivity of the area and rainfall shortage, it causes changes in the flow and sediment regime, water resources, agriculture, and so on. Since plants react more precisely to t...
متن کاملFlood hazard zones using 2d hydrodynamic modeling and remote sensing approaches
Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...
متن کاملImproving Volunteered Geographic Data Quality Using Semantic Similarity Measurements
Studies have analysed the quality of volunteered geographic information (VGI) datasets, assessing the positional accuracy of features and the completeness of specific attributes. While it has been shown that VGI can, in some context, reach a high positional accuracy, these works have also highlighted a large spatial heterogeneity in positional accuracy, completeness but also with regards to the...
متن کاملEvacuation Modeling Framework Using Volunteered Geographical Information. In Large Scale Pedestrian Evacuation Modeling Framework Using Volunteered Geographical Information
With rising instances of extreme events and urban settlements, this paper outlines a pedestrian evacuation modeling framework using volunteered geographical information from OpenStreetMap and simplified queuing-network model to estimate evacuation time, detect bottlenecks and test different evacuation strategies. An example case of a total city wide evacuation is presented for a selection of UK...
متن کاملFlood Damage Modeling on the Basis of Urban Structure Mapping Using High-Resolution Remote Sensing Data
The modeling of flood damage is an important component for risk analyses, which are the basis for risk-oriented flood management, risk mapping, and financial appraisals. An automatic urban structure type mapping approach was applied on a land use/land cover classification generated from multispectral Ikonos data and LiDAR (Light Detection And Ranging) data in order to provide spatially detailed...
