The verification of the existence or lack of accessibility equipment at bus stops and parking areas close to tourist attractions relies on current legislation （NBR 9050/1994） that establishes the right to accessibility for disabled people to transportation, local culture and leisure. An application that facilitates this recognition with low operating costs and high performance was developed using the OS software Quantum GIS 1.0.2, Apache 2.2.4, Mapserver 5.0.2, I3GEO 4.0, PostgreSQL 8.3 and PostGIS 1.3.5. This software is able to integrate the management of tourist areas and the advertisement of tourist information regarding accessibility devices at sights recognized as tourist attractions by Campinas city hall.展开更多

This paper introduces a Web GIS solution has been applied to establishing “The Mekong Delta Geographic Information Systems—MGIS”. The development and implementation of a web-based MGIS are a suitable technology for monitoring and managing the natural resources and environment that aims to achieve sustainable development in the Mekong Delta region. The proposed solution shows that Web GIS can be applied effective to for integrating and sharing data among administration agencies in order to provide fully integrated information of updated on the status of land cover changes and analyzing the trend of forest-cover changes in this region. Results of this study illustrate the MGIS’s applications in sharing of regional data that allows multiple users to use tools for displaying spatial distribution of forest-cover in the period from the year 1990 to 2015 and analyzing the trend of changes.展开更多
