This chapter reviews the technology, data, and implications related to the Geospatial Web (Geoweb). The unprecedented volume of geographic information (GI) being created, made available, editable, and distributable presents challenges and opportunities for information professionals related to GI access and use. Usability, functionality, and accessibility issues for web-based mapping applications and location-based mobile applications provide one stream of research for Information Science. The Geoweb, as both the cyberinfrastructure and the information space for GI, requires some re-framing of the various resources that support discovery. The contextualization of the user roles, communities, and GI types provide other new avenues of research in Information Science related to human information seeking behavior and the digital curation of all types of information.
