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