An Architecture for Geographic Information Systems on the Web - WebGIS

摘要

Geographic Information Systems for the web (webGIS) are being implemented for different purposes. In this context, one of the greatest challenges is to integrate different sources of geographic data, as well as the visualization of this information using maps in an interactive environment. This paper presents a proposal for architecture for the webGIS with interoperability between different sources of heterogeneous data, as well as the visualization of maps in different formats with components implemented with Web 2.0 technology. The architecture was validated through a case study that implemented a webGIS to academic research at the Geosciences Institute of the University of Brasilia.
