A Geospatial Web (pronunciation: 'gēō-spãy-shee-ăl wěb') or Geoweb is a computer network which pairs geographic (e.g. two-dimensional maps) or geospatial (e.g. three-dimensional pictures) underlay systems with a Geotag overlay system for the purpose of connecting users with other network locations. Today's free and popular Geobrowsers are examples of simple Geoweb service implementations. Complex Geoweb services provide users access to applications and files, within the context of specific physical locations on earth.

The concept of a Geospatial Web may have first been introduced by Dr. Charles Herring in his US DoD paper, An Architecture of Cyberspace: Spatialization of the Internet, 1994, U.S. Army Construction Engineering Research Laboratory (Lua error in Module:Coordinates at line 668: callParserFunction: function "#coordinates" was not found.).

Dr. Herring proposed that the problem of defining the physical domain in a computer or cyber-infrastructure, providing real time and appropriate fidelity, required a cyber-spatial reference or index combining both Internet Addressing and Hierarchical Spatial Addressing.

As such, the Geoweb would be characterized by the self synchronization of network addressing, time and location. The Geoweb would allow location to be used to self organize all geospatially referenced data available through the Internet.{}

The interest in a Geoweb has been advanced by new technologies, concepts and products, specifically the popularization of GPS positioning with the introduction of the iPhone in 2007.

Virtual globes such as Google Earth and NASA World Wind as well as mapping websites such as Google Maps, Live Search Maps, Yahoo Maps, and OpenStreetMap have been major factors in raising awareness towards the importance of geography and location as a means to index information.

The increase in advanced web development methods such as Ajax are providing inspiration to move GIS (Geographical Information Systems) into the web.

GeoTags are Icons located within GeoBrowsers which, when clicked, perform a computing operation. In 2012, David Joshua Plager, AIA, conjectured that GeoTags, located within GeoBrowsers and associated with Postal Addresses, would, in the future, be relied upon by the Users of one or many Security as a Service Corporation(s) to connect individuals, businesses and machines working on and sharing proprietary (building) information.

Geographic Information Retrieval (GIR) has emerged as an academic community interested in technical aspects of helping people find information about places. In order to make information accessible from geographically oriented applications, coordinate metadata must be created via some form of geocoding or geoparsing process. After obtaining geographic coordinates, they must be indexed in useful ways that allow people to interact with the non-geographic nature of the content, e.g. viewing photographs or keyword searching.

The semi-annual Geoweb Summits in New York have covered the emerging geoweb industry since 2010, connecting GIS and mobile LBS with Internet of Things and augmented reality.
