Thanks for your thoughtful comment. In fact - this is exactly what we are working on now. In just 6 weeks since the interview, a lot can change and adjust and grow in this kind of environment!

We are planning for a new series of mappings and information/feedback gathering in health and schools as well as other themes. In two weeks we'll cover Kibera again looking for additional health data and confirming the data collected already. This will include a few simple questions such as services provided at each clinic, which will be added to the base map database. Already we have imaginative volunteers who can then layer with other data as you suggest. Meanwhile, we can illustrate these places with short video clips or photos taken by the mappers (just initiating a video news team now as well). Then, community meetings with printed maps will allow people to comment and correct or draw on maps for more depth, and I am sure they will come up with ideas we hadn't thought of yet to use the info in order to improve services.

Our goal is to help provide these elements which other creative folks can mix and mash, in particular to support advocacy needs in the community. Budget layering will definitely be interesting.
