I really enjoyed reading Haklay and Tobon’s (2003) article on PPGIS because it examines concepts that I can relate with my term project. The authors believe in information contributed by non-expert users in a constraint free environment; away from the office, possibly work, in your own personal space, or on the go. A decade after this article was written, mobile phones, especially smartphone apps, allow a user to both contribute and interact with non-expert generated information. I believe an ultimate PPGIS synergy has been created by linking FOSS together, in particular Ushahidi and OpenStreetMap, to represent geographic data contributed by non-expert users; on an online platform where you can text, email or Tweet information that you can then view interactively, on an OpenStreetMap interface.
User-centered design, development and deployment, and geovisualization are all critical components to a successful, efficient and usable platform. From the end-user perspective, these are all achieved. However, feelings may be mixed for developers. It is one thing to be able to send a text, Tweet, or email to a platform and interact with it, and another to use it as a template, activate, and maintain that platform. As much as these platforms are user-friendly, when will they become developer friendly? By developer I don’t mean a computer programmer, or a developer that is comfortable with coding, but someone who is new to it all but wants to learn; the non-expert of developers. Given all of this, I wonder what the authors would say of Ushahidi now. I believe in a constant need for improvement of open-source platforms, to strengthen the world of PPGIS. As difficult as the building process of the Ushahidi template can be for a newbie developer, I am astounded by the impact it has had and continues to have on the world of non-expert users.
