The document discusses the evolution of geographic information systems (GIS) and their relationship to social web technologies. It provides a brief history of GIS, from early mapping efforts to modern systems created in the 1960s-1990s by ESRI. It then discusses how GIS provides data that can be used to create mashups and geospatial applications on the social web. One example discussed is extending wiki systems to allow users to geographically tag and edit map data, creating a "wikified" GIS archive. The document concludes that GIS serves as a backend for geospatial applications on the social web by allowing users to collaboratively contribute and update map layers.

Hello. My name is Paul Swenson, and I am a Computer Science graduate student. This presentation is entitled “Evolution of GIS Technologies in a Web 2.0 World.” Within this presentation, I will be going over the basic concepts of Geographic Information Systems, how they relate to Social Web Technologies, and also some interesting and relevant research efforts going on today in the wide world of academia.
