Information visualisation (IV) involves representing information visually as a mean of getting insight into data. Many techniques are available in visualising information, with city/urban planning as one of them. The challenge that lies with city/urban planning technique in Information Visualisation is how to enhance the information legibility as to assist users in their wayfinding task. Univer...

Visualization is the graphical presentation of information, with the goal of improving the viewer’s understanding of the information contents. As today’s world is getting richer in information, visualization of the information is important for effective communication and decision making. In this study, generation of a 3D city model in CAD environment and its use in a spatial decision support sy...

Evaluation on ecological environment system is to describe and assess the quality of ecological environment, and accurately reflect the ecological environmental quality and pollution situation. In this paper, after reviewing the domestic and foreign relative researches, from the theory perspective of the dissipative structure of complex system, we analyzed the city ecological system dissipative...

Urban waterlogging and urban water environment problems in Changde city caused by extreme weather have seriously hindered the sustainable development of cities. A sponge not only involves inheritance foreign technology but also a new method for its use. The background construction based on green infrastructures China was introduced this study. As one first pilot cities concept, possesses natura...

A growing body of evidence supports the association between the built environment and children walking to school (WTS), but few studies have compared WTS behaviors in cities of different sizes. This case-comparison study utilized WTS data from fourth graders in the small city of Manhattan, KS, USA (N = 171, from all eight schools) and data from fourth graders in the large city of Austin, TX, US...

Surficial sediment samples were collected from Hochiminh City canals, the Sai Gon-Dong Nai River, and its estuary, one of the most predominant industrial areas in Hochiminh City, southern Vietnam, for determination of selected persistent organic pollutants (POPs). Contamination pattern was as follows: PCBs > or = DDTs > HCB > CHLs > HCHs. Concentrations of PCBs and DDTs ranged from 0.50-150 ng/...

Using the recently developed 3D GIS (Geographic Information System) and related visualisation technologies, we have created a digital diorama of an entire historical city, which can be used to virtually travel through different realistic landscapes at different times in the history. The digital diorama called Virtual Kyoto is the virtual geographic environment of the past, present, and future o...

Web-based 3D GIS becomes one of the major areas of GIS research, which extend distributed virtual geographic environment when integrated with virtual reality. Distributed virtual city environment, one of the most important research fields, will meet the demands of the urban planning and urban landscape. Firstly, a CORBA-based distributed architecture is presented. Secondly, a new 3D LOD buildin...

Since the last decades the availability and granularity of location-based data has been rapidly growing. Besides the proliferation of smartphones and locationbased social networks, also crowdsourcing and voluntary geographic data led to highly granular mobility data, maps and street networks. In result, location-aware, smart environments are created. The trend for personal self-optimization and...
