Geo-information techniques have proven their usefulness for the purposes of early warning and emergency response. These techniques enable us to generate extensive geo-information to make informed decisions in response to natural disasters that lead to better protection of citizens, reduce damage to property, improve the monitoring of these disasters, and facilitate estimates of the damages and ...

Widespread use of spatial databases[24] is leading to an increasing interest in mining interesting and useful but implicit spatial patterns[14, 17, 10, 22]. Efficient tools for extracting information from geo-spatial data, the focus of this work, are crucial to organizations which make decisions based on large spatial data sets. These organizations are spread across many domains including ecolo...

With the convergence of wireless communication, mobile positioning and GIS technologies, the demand for location based services (LBS) has already appeared and prompted research in different fields. Location based applications and services deliver geo-data and real-time information to mobile users in accordance with their locations and preferences. In this paper, we present our data model of mob...

Abstract El-Gendi Fortress is a unique geo-archaeological site in Sinai, Egypt. It reflects the progress of Islamic military architecture during Saladin’s reign (Salah ad-din al Ayyubi), founder Ayyubid dynasty (1174-1260AD). The fortress's location met two major geo-criteria. One geographical; it located on mound 655 m above sea level (a.s.l) and 152 El-Tih El-plateau; this elevation contribut...

Pervasive presence of location-sharing services made it possible for researchers to gain an unprecedented access to the direct records of human activity in space and time. This article analyses geo-located Twitter messages in order to uncover global patterns of human mobility. Based on a dataset of almost a billion tweets recorded in 2012, we estimate the volume of international travelers by co...

The creation of detailed 3D buildings models, and to a greater extent the creation of entire city models, has become an area of considerable research over the last couple of decades. The accurate modeling of buildings has LBS (Location Based Services) applications in entertainment, planning, tourism and e-commerce to name just a few. Many modeling systems created to date require manual correspo...

POI, or Points of Interest, refer to the geo-position points in maps. POI provided by Baidu Maps come from different sources. To assure the quality of POI, Baidu checked the validity of every POI and merged them into a standardized dataset. By comparing names and spatial coordinates of POI, calculating similarities and hashing, Baidu built its own POI dataset with a precision higher than 95%. A...

BACKGROUND Medical tourism - travel across international borders for health care - appears to be growing globally, with patients from high-income nations increasingly visiting low- and middle-income countries to access such services. This paper analyses Australian television and newspaper news and current affairs coverage to examine how medical tourism and these destinations for the practice ar...
