This document describes a heatmap analysis of health facility distribution in Haiti. It obtains hospital location data from OpenStreetMap, population data from haitidata.org, and generates a heatmap based on travel times to the nearest hospital. The analysis incorporates population density to better evaluate service gaps. It was created using Django, GRASS, PostgreSQL/PostGIS, and other open source technologies. The roadmap includes improving the algorithm and collecting better data with the OSM community.

2. The problem
How can we evaluate the distribution of
a service (e.g. hospitals)?
This information can be useful to:
Show the gap of ser vices
Improve future planning
Make ser vices more efficient
Correlate population with ser vices

3. Our solution
Get hospitals from OpenStreetMap
Get street information from
OpenStreetMap
Build heatmap based on time-travel routes
to the nearest hospital
Get population infromation from
haitidata.org
Elaborate the informations with population
density
