This is a really interesting project. Can you speak more to the choice of SMS as the dissemination solution? What do those alerts look like?

Regarding question 2, we have three basic requirements for the geospatial data: 1) Improve mapping of buildings / structures in densely populated areas with high resolution imagery in order to improve population estimates; 2) Gather adequate imagery to also augment existing transportation data, especially for smaller (e.g. motorbike, foot, bicycle) modes of transport; 3) Augment with focused on-the-ground knowledge to refine the above estimates.
These three pieces then become the starting point for modeling franchise locations and opportunities.
