Title - Research on Volunteered Geographic Information: User-generated
GIS geospatial content
Presenter - Michael F. Goodchild, Chair, Geography, UCSB, Director,
Center for Spatial Studies / Center for Spatially Integrated Social
Science

Abstract - In recent years a significant new source of geographic
information has become available as a result of the activities of large
numbers of neogeographers -- individuals who are largely without
training in geography, cartography, or GIS. I review a selection of
examples and discuss defining dimensions that emerge from an inventory
of prominent sites. VGI is a subset of user-generated Web content, and
raises similar research questions: who contributes and why, what do they
contribute about, what is the quality of the result, and what can be
done with this new information source? I discuss the results of research
on the geographically tagged content of Wikipedia, as well as other
projects that are shedding light on these questions. VGI has a special
role to play in providing timely updates, especially in time-critical
situations such as emergencies, and I review the experience of the past
two years of wildfires in Santa Barbara. VGI is potentially useful in
science, as a form of citizen science and a source of soft data. I
conclude with some findings regarding data quality, and the special
conditions that attach to geographic information.
