Polarimetric SAR feature selection using a genetic algorithm

One of the main applications of polarimetric synthetic aperture radar (POLSAR) images is terrain classification. In this study, an algorithm is presented to extract optimized features of POLSAR images that are required for classification. The proposed algorithm involves three main steps: (i) feature extraction using decomposition algorithms, including both coherent and incoherent decomposition alg

Design and implementation of a distributed Web-based system for itinerary planning in uncertain urban multimodal network

Today’s traffic is one of the main concerns of urban managers. One of the solutions that have been proposed to reduce traffic is encourage people to use public transport instead of personal vehicles, so the quality of public transport should be increased. One way promoting public transport systems quality is creating urban traveler guidance system. In other hand, public transportation network is l

Design and Development of an Event-based Model for Geo-spatial Information Systems in Accordance to the Concept of Dynamic Version

Effectiveness of management would be seen when we have to ensure the accuracy of the output. This is possible if the model predictions are done based on the behavior of desired phenomena in the real world, using appropriate organizing data in a Geo-spatial Information System. Therefore all the aspects of a phenomenon must be considered. But most Geo-spatial Information Systems' databases use a ver

Spatial and Temporal Analysis of Fires Detected by MODIS Data in Northern Iran From 2001 to 2008

Fire, a natural disaster, has significant effects on ecosystems and plays a major role in deforestation, and it is a major source of trace gases, aerosols and carbon fluxes. Remote sensing is a valuable data source to investigate different phases of fire management. The Moderate Resolution Imaging Spectroradiometer (MODIS) has been designed to include specific characteristics for fire detection. I
