ABSTRACT: Geographic information and geo-technologies are essential for the municipal administration to learn the reality of the city and its infrastructure. Spatial Data Infrastructures promote data sharing and access to data by the community in an easy and effective way. However, acquisition and update of spatial data has changed in recent years because it is a time-consuming activity and of costly implementation. In this context, volunteered contribution can complement the efforts for mapping geographic information. This paper proposes an architecture for information systems that receive volunteered geographic information in a SDI at the municipal level. Among the contributions of this work is the adaptation and integration of a SDI architecture to services that include new collaborative components.
