Crowdsourced and volunteered geographic information are concepts that have become of great interest to cartographers and GIScience professionals. Maps that rely on user-contributed data, called wikimaps, are becoming more mainstream and represent a major player in the future of web cartography. The most cited example, OpenStreetMap, now has a community of over 1.6 million users. But many questions remain about how such maps should be designed: How should such data be symbolized? How can it be judged for quality? How should ethics be applied in light of privacy concerns? How small-d democratic is the crowd really, and how are crowdsourced maps really being used? These are just a few. This talk presents my experience to date creating and using wikimaps, with a focus on preliminary conclusions and questions for further investigation.

#13: Only about 30% registered users have ever contributed geographic information. Among those contributors, about 40% have contributed only once since they joined the project Further, we find that mappers are predominantly from Europe and North America, indicating a long way for VGI to be a universal source of GI. [Budhathoki and Nevodic-Budic 2010, 1]. 87% of edits to heavily-edited objects are performed by 11% of the total contributors. [Mooney and Corcoran 2012]
#14: Some expert guidance may be necessary to enable traditionally underrepresented groups to participate.
#15: Is part of the solution superficial interface design, UI controls, etc? Would better symbolization attract more contributions? What about user rating systems and connections to social media?
#16: Can we distribute wikimap VGI contributions to non-white, non-male, non-First World people? Should we? What are the stats on Ushahidi and other such targeted projects?
#17: And what about CGI? There may be a fine line between empowerment and surveillance.
