I agree with everything here, you should be able to use MapBox or something similar and be able to easily integrate their API's. On a design note, I would look at your color palette and try to find things that have better accessibility for those with vision impairment and I feel some of the categories could be methods you could filter within the categories as an example:

- Hospitals
 Services:
   - Ambulance
   - Oxygen
   - Etc.

True. The page is too "colorful" and not good for those who just want to find the information. And he is using the same color for some categories, leading potentially misunderstanding. The thing can be as simple as a filtered Jquery Mobile Table component.Anyway filters is better then distinguishing by colors. 

Personally I think this might look better:
