The California Seismic Hazards Mapping Act of 1990 directs the California Geological Survey (CGS) to delineate seismic hazard zones of required investigation for earthquake-induced ground failures specifically, liquefaction and seismically triggered landslides. To date, more than 100 official Seismic Hazard Zone maps have been released, covering 200 cities and unincorporated areas in ten counti...

Recent researches on Three-dimensional Geographic Information System (3D GIS) modeling technology were reviewed. The concept of 3D GIS modeling and its application in various fields were introduced. Essential techniques to realize 3D visualization were studied. A typical 3D GIS modeling usually contains the description and the transmission of GIS spatial data structure. GIS spatial data models ...

This paper studies the development of GIS from a new point of view, which both from the accumulation of GIS scientific articles and the evolution process of GIS using co-citation analysis. After 10 years’ slow development from 1977, the number of GIS scientific literature began to increase rapidly since the early 1990s. By using the newly developed information visualization technology, the auth...

Due to the driving forces of the Internet and network communication technology, the paradigm of Geographic Information Systems (GIS) is shifting [16, 19]. Moreover, with the advances in computer technology and GIS science, distributed GIS become practical and widely acceptable. Traditional GIS plays an extremely valuable role in GIS applications by providing a wide variety of tools to handle ge...

Today, we hear more Mobile, and find some mobile GIS application in our everyday life, such as GPS car management However, what is mobile GIS? What is the difference among Static GIS and Temporal GIS? This seems to be the first step to study mobile. The paper, it gives the concept of mobile GIS, the system Architecture of Mobile GIS, the key research area in mobile.

Introduction: Significant challenges face any user of planetary hyperspectral imagery. For the scientist, the sheer volume of data precludes exhaustive manual analysis. For the mission planner, the complex subtleties of hyperspectral images are difficult to summarize in a readily interpretable product. Both experts would benefit from a rapid, robust means to create draft mineralogical maps, sum...

Courtyards are a passive strategy to improve the energy performance of buildings. However, accurate simulation courtyards’ thermodynamic in early design stage is still challenging, even though there has been an emergence new methods assess outdoor simulation. This paper tests novel workflow using Ladybug Tools that uses CFD for temperature and comfort courtyards suitable building design, compar...

BACKGROUND An extensive West Nile virus surveillance program of dead birds, mosquitoes, horses, and human infection has been launched as a result of West Nile virus first being reported in Canada in 2001. Some desktop and web GIS have been applied to West Nile virus dead bird surveillance. There have been urgent needs for a comprehensive GIS services and real-time surveillance. RESULTS A pilo...
