[talk-ph] Update imagery index

[maning sambale]

Can somebody update our Imagery Index coverage:
http://osmph.github.io/Imagery_Coverage_Map/

We need to identify what areas needs more imagery (pre or post).

Code and instructions here: https://github.com/OSMPH/Imagery_Coverage_Map
I can merge any pull requests, I just don't have good bandwidth to
check all areas.

A list of avalibale imgery here:

Thanks!
