The past decades have witnessed the rapid growth of heterogeneous geospatial information systems. An important way to share these valuable assets is a spatial data infrastructure (SDI). Recent developments in Web Services and distributed geospatial information services(Yang et al., 2005) provide a practical approach, Web Portals, to building a SDI. This article describes research, development, and challenges related to Web Portals for SDI.
