I wanted to share with you this visualization of geo-tagged articles from South Asia, including India. Please see the image
here. The analysis was conducted by a researcher at the Oxford Internet Institute, Mark Graham, who has been conducting research on geo-location and Wikipedia. The data is only from English Wikipedia. It is interesting to note concentration of geo-tagged articles from Kerala, Nepal and Indian metropolises: Mumbai. Delhi, Chennai etc. Mark has done more analysis in his blog, and he informed me that he would love input from the community in India. If you would like, please provide him insights through the comment section.
Mark has been using publicly available data to conduction geo analysis of Wikipedia articles, and editors. If you would like to read more about his research, you can visit his website
