No. of bitstreams: 1 IgorPSC.pdf: 2186832 bytes, checksum: 1d9baf4d29f0a33456e0ca308b9dd55e (MD5) Previous issue date: 2006-02-17 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / In this work, we propose a Geographical Information System that can be used as a tool for the treatment and study of problems related with environmental and city management issues. It is based on the Scalable Vector Graphics (SVG) standard for Web development of graphics. The project uses the concept of remate and real-time mar creation by database access through instructions executed by browsers on the Internet. As a way of proving the system effectiveness, we present two study cases;.the first on a region named Maracaja? Coral Reefs, located in Rio Grande do Norte coast, and the second in the Switzerland Northeast in which we intended to promote the substitution of MapServer by the system proposed here. We also show some results that demonstrate the larger geographical data capability achieved by the use of the standardized codes and open source tools, such as Extensible Markup Language (XML), Document Object Model (DOM), script languages ECMAScript/ JavaScript, Hypertext Preprocessor (PHP) and PostgreSQL and its extension, PostGIS / Neste trabalho, propomos um Sistema de Informa??es Geogr?ficas voltado para a Web que sirva de ferramenta base para o tratamento e estudo de quest?es relacionadas com o meio-ambiente e gest?o de cidades, baseado no uso do padr?o Scalable Vector Graphics (SVG) para desenvolvimento gr?fico na Web. O projeto utiliza o conceito de cria??o remota e em tempo real de mapas atrav?s do acesso ao banco de dados pelas instru??es executadas pelos browsers na rede mundial de computadores. Inicialmente a ?nfase ser? direcionada aos parrachos de Maracaja?, localizado no litoral do Rio Grande do Norte, e logo ap?s a um estudo realizado na regi?o Nordeste da Su??a em que se prop?e a substitui??o do MapServer pelo sistema a ser discutido. Dessa forma, ser?o debatidos resultados que demonstram a maior capacidade de representa??o de dados geogr?ficos mediante a utiliza??o de c?digos padronizados e fontes abertas, tais como Extensible Markup Language (XML), Document Object Model (DOM), linguagens de script ECMAScript/ JavaScript e Hypertext Preprocessor (PHP), bem como o Sistema de Gerenciamento de Banco de Dados PostgreSQL e sua extens?o, o PostGIS
