The quality and life of pavement is greatly affected by the type of sub-grade, sub base and base course materials. The most important of these are the type and quality of sub-grade soil. But in India most of the flexible pavements are need to be constructed over weak and problematic sub-grade. The California bearing ratio (CBR) of these sub-grade have very low, it needs to more thickness of pav...

The recent advances in geo-informatics have been opening new opportunities in earthquake early warning and emergency management issues. In the last years, the geo-scientific community has recognized the added value of a geo-analytic approach in complex decision making processes for critical situations due to disastrous natural events such as earthquakes. In fact, recently, GIS-based solutions a...

Earth’s life-support systems are in flux, yet no centralized system to monitor and report these changes exists. Recognizing this, 77 nations agreed to establish the Group on Earth Observations (GEO). The GEO Biodiversity Observation Network (GEO BON) integrates existing data streams into one platform in order to provide a more complete picture of Earth’s biological and social systems. We presen...

The structure of the network forming glass GeO(2) is investigated by making the first application of the method of in situ neutron diffraction with isotope substitution at pressures increasing from ambient to 8 GPa. Of the various models, the experimental results are in quantitative agreement only with molecular dynamics simulations made using interaction potentials that include dipole-polariza...

Geo-DBMSs make it possible to manage large spatial datasets in databases that can be accessed by multiple users at the same time. These spatial datasets usually contain 2D data, while more and more applications depend on 3D data. Some examples are 3D cadastres [1], telecommunications [2] and town planning [3]. These applications mainly come from the ever-growing tendency of using living space m...

Users’ interaction and collaboration on Web 2.0 via social bookmarking applications have resulted in creating a new structure of user-generated data, denoted folksonomies, where users, Web resources and tags generated by users are linked together. Some of those applications focus on geographic maps. They allow users to create and annotate geographic places and as such generate geo-folksonomies ...

Recently, various services using the location information are developed with the wide spread of smartphones. Geo-fencing is one of the services. In Geo-fencing services, terminals automatically carry out the some processing associated with the virtual border when they detect that themselves passes the border. However, it is a problem that power saving of Geo-fencing service covering over indoor...

Ontology is an explicit specification of a conceptualization in Artificial Intelligence. Geo-ontology is a very complex and intricate concept. Lots of researchers begin to research Geo-ontology, but many of them just transplant ontology concept of information science into GIS. Based on existed expert’s knowledge, starting from the basic components, we determine the scope of Geoontology at first...
