The web feature service: transaction standard: an example of prototype implementation

Trabalho de Projecto apresentado como requisito parcial para obtenção do grau de Mestre em Ciência e Sistemas de Informação Geográfica

With the Internet growth, the production and amount of available geographic data also increased. There are, at the moment, many servers around the world providing spatial information to several users, and many of them are accessing this information through different Geographic Information Systems (GIS) applications. Therefore, it becomes necessary to develop standards in order to solve the interoperability problem inherent to this heterogeneous and distributed data. This work aims at showing the significance of standards, particularly the Web Feature Service - Transaction (WFS-T) standard in the Geographic Information (GI) domain. A prototype that provides GI according with this standard is also implemented, based on PostgreSQL/PostGIS, GeoServer, uDig, Apache and MapFish.
