In this paper we present our experience in the development of a geographic information system that includes a large database (over 7 GB) with information about the infrastructure and facilities of the municipalities in the province of A Coruña (northwestern Spain). Three interesting aspects of the whole project are described in some detail due to their intrinsic interest for the development of this kind of system. These aspects are: (1) the design of the data model and the system architecture, which is oriented to support some advanced features such as multiscale active maps; (2) the problem of designing appropriate workflows to populate the database; and (3) the design of a Web‐based application to exploit the geographic database through a user‐friendly interface.
