For some emergency situations an effective response can be reliant on sensor data (e.g. river level, traffic flow, weather conditions) to provide situation awareness, in order to help authorities make informed decisions. Gathering data in a traditional approach, i.e. using precise physical sensors, is a highly expensive task, involving procurement, installation and maintenance of a number of se...

Zusammenfassung Warping ist eine Klasse von Bildverarbeitungsverfahren, die durch Neude nition raumlicher Beziehungen einzelner Bildpunkte zwei Bilder nicht-a n geometrisch transformieren. In dieser Arbeit de nieren homologe St utzpunkte jeweils Verschiebungsvektoren. Die Verschiebung jedes Voxel wird durch die gewichtete Summe aller dieser Verschiebungsvektoren berechnet. Das jeweilige Gewic...

The structures of three xGeO(2)-(1- x)P(2)O(5) glasses, where x = 0.98,0.88, and 0.81, have been studied by neutron and x-ray diffraction experiments that yield well resolved P-O and Ge-O bond distances. The Ge-O coordination number (N(GeO)) increased from 4.0 ± 0.2 to 4.5 ± 0.2 with the decrease in x from 0.98 to 0.81. The increase in N(GeO) is consistent with a structural model that assumes t...

3D geo-database research is a promising field to support challenging applications such as 3D urban planning, environmental monitoring, infrastructure management, and early warning or disaster management and response. In these fields, interdisciplinary research in GIScience and related fields is needed to support the modelling, analysis, management, and integration of large geo-referenced data s...

in this comment, i build on shiffman’s call for the global health community to more deeply investigate structural and productive power. i highlight two challenges we must grapple with as social scientists carrying out the types of investigation that shiffman proposes: the politics of  challenging the powerful; and the need to investigate types of expertise that have traditionally been thought o...

In the last 30 years, China’s economic power has experienced great changes and has brought about a profound impact on the world economy. This led us to ask a question: do changes in China’s economic power shift the geo-economic relationships between China and its neighboring countries? To answer this question, we researched the evolution of geo-economic relationships between China and the Assoc...

Geographic information services (geo-services) are gaining popularity as an efficient and costeffective framework for integrating geo-information systems, within and between enterprises, to enhance enterprise business processes. Geo-services can be chained dynamically to create customised geo-information and value-added services and therefore offer a business opportunity for disparate partners ...

From the perspective of spatial information sharing and interoperation, the concept of geo-ontology has been proposed in this paper. At first, a brief introduction to the Geo-Ontology concept has been described and the hierarchical structure of geo-ontology has also been analyzed. Then, the traditional method of ontology construction has been discussed and the existing problems have also been s...
