With the phenomenal growth of the WWW, rich data sources on many different subjects have become available online. Some of these sources store daily facts that often involve textual geographic descriptions. These descriptions can be perceived as indirectly geo referenced data - e.g., addresses, telephone numbers, zip codes and place names. Under this perspective, the Web becomes a large geospatial database, often providing up-to-date local or regional information. In this paper, the authors focus on using the Web as an important source of urban geographic information and propose to enhance urban Geographic Information Systems (GIS) using indirectly geo referenced data extracted from the Web.
