Using Open Source GIS in e-Government Applications

Geographical Information System (GIS) plays an important role in e-government applications once that all government information has a geographic dimension – a street address, a transportation road, a river, a city, a state and so on. GIS apart from contributing for data integration from different data sources, enables data visualization using maps, which enhances the system usability and can help the decision-making process. This paper describes a web GIS framework that provides fast and easy deployment of e-government applications. The framework is validated by the realization of a substantial application of a Brazilian state, which contains data about health, education, industry, human development index and other socio-economic data.
