INTRODUCTION: Pre-crisis planning is one of the important issues facing managers and planners, especially in the field of crisis management. In recent years, the world has faced an increasing number of natural and man-made disasters, such as earthquakes. Moreover, the growing effect of disasters on communities has highlighted the need for efficient and effective emergency logistics operations i...

Network positioning systems are essential to good performance in distributed systems that scale to millions of end hosts. Evaluating performance in this environment is particularly challenging. This paper addresses this issue through an empirical study of two alternative classes of network positioning services based on a dataset gathered from more than 43K IP addresses probing over 8M other IPs...

In the past, several firefighters have died in disaster relief operations. Although were fully equipped, scene of was smoky and disorienting, making unable to identify their location. The commander wanted direct outside but could not confirm correct location firefighters, causing delays rescue. GPS cannot support indoor positioning or preset facilities at moment fire extinguishing. However, geo...

This abstract addresses challenges and strategies for wireless positioning. The anisotropic network localization problem and the solutions are discussed for wireless sensor networks. Applications of Bayesian filters are introduced to track positioning parameters in global navigation satellite systems. Radio map-based positioning solutions robust to the received signal strength variation are als...

Intelligent seamline selection for image mosaicking is an area of active research in the fields of massive data processing, computer vision, photogrammetry and remote sensing. In mosaicking applications for digital orthophoto maps (DOMs), the visual transition in mosaics is mainly caused by differences in positioning accuracy, image tone and relief displacement of high ground objects between ov...

For land use monitoring, the main problems are robust positioning in urban canyons and strong terrain reliefs with the use of GPS system only. Indeed, satellite signal reflection and shielding in urban canyons and strong terrain relief results in problems with correct positioning. Using GNSS-RTK does not solve the problem completely because in some complex situations the whole satellite's syste...
