The goal of this research is to find the most suitable computer simulation software for assessment of urban design performance from physical point of view. Although there are many physical simulation tools available today, there is no one which covers all the needs of urban design. After initial research of available software, we have chosen to assess three applications: ENVI-met, Project Vasar...

Georeferencing images is a laborious process so schemes for automating this process have been under investigation for some time. Among the most promising automatic registration algorithms are those based on the fast Fourier transform (FFT). The displacement between two given images can be determined by computing the ratio F1 conjðF2Þ=jF1F2j; and then applying the inverse Fourier transform. The ...

Thematic mapping is one of the major application fields of remote sensing techniques. Data quality of the thematic data was concerned about. At present, there are a lot of researches that focus on the uncertainty measures, modeling and visualization. But lacking an easy-to-use visualization system of classification uncertainty. The research work toward how to use uncertainty, especially how to ...

In the process of high resolution images orthorectification, an uneven distribution of ground control points in mountainous area results in the phenomenon of ground objects dislocation between orthophotos edges in the overlap area. Followed image mosaic, fusion and interpretation are seriously affected. High-resolution (2.5 m) panchromatic images with a 30% forward overlap of ALOS satellite wer...

ABSTRACT This paper describes the Active Response GIS (AR/GIS) for resource planning and land­ allocation deliberation. AR/GIS is an integrated system which combines GIS and electronic meeting software. This combination provides the voting, information organization, and brainstorming of an electronic meeting system, and supports interaction with geographic data sets. The AR/GIS system can impro...

The catalytic boost of critical mass usage of the World Wide Web (WWW) has brought about the shift in the traditional geographic information systems (GIS) paradigm and engendered new challenges and opportunities. The traditional GIS paradigm involves the use of huge databases and large expensive GIS software packages confined to local disks. The new paradigm, however, enables geospatial data to...

This paper provides detailed examinations on the use of GIS in nonprofit organizations. We interviewed planners and GIS experts in key nonprofit organizations in the City of Chicago to comprehend their actual usages of GIS, faced challenges, and accumulated experiences. Organizations reported on dozens of projects where GIS was used for practical urban planning applications. Findings indicate t...

Virtual reality is becoming a popular tool to visualize 3D GIS data. Direct interaction with the GIS data, however, is often limited. In this paper, we present a multi-view approach to support 3D GIS interaction within VR-environments. This approach is implemented in the Karma VI system, using existing GIS and VR technology. We describe the multi-view approach, the system components and the int...

The vegetation cover of the Ouémé Delta constitutes a biodiversity hotspot for wetlands in southern Benin. However, overexploitation natural resources addition to intensification agricultural practices led degradation ecosystems this region. present work aims reconstruct, using remote sensing, spatial dynamics land use order assess recent changes and predict trends its cover. methodology was ba...
