Mapping Emergency Health Services in Senegal

Defining the scope and service provision capacities of Emergency hospital


“OpenStreetMap Senegal are mapping public hospitals in Senegal and updating the emergency health services available. This is part of a larger campaign from to define emergency health services across Africa.”

“We compare open data from OpenStreetMap hospitals with an open data set developed by the KEMRI-Wellcome research program in 2018 and currently hosted by WHO. With the support of Afrimapr, we establish R building blocks to allow personalized analysis using open source packages. We monitor progress in terms of entering additional health facility data into OSM through the Ohsome application developed by HeiGIT and afrihealthsites developed by afrimapr.”



At the start of this project had collected information on 1,221 health facilities in Senegal with most of them based in Dakar. Only partial information was available for all facilities listed in This meant that most entries did not list details critical to support humanitarian responses.


Emergency health user stories

How to drive development of the data

We take a Human Centered Design to drive the development of baseline health facility data. We invite specialists to share user stories that communicate emergency health needs in parts of the world where service is poor. This helps us identify the baseline health facility attributes to focus on.


Deconstructing user stories

When we deconstruct user stories, we can understand what kind of information is needed to support the story. Our examples are deconstructed in the table below…


User story example 1

"As an epidemiologist I want to know the number of hospital beds at a health facility so that I can assess the capacity to manage a disease outbreak event - Beds (no.)"

User story example 2

"As a citizen responding to a road accident I want to know where the nearest emergency facility is so that we can get there quickly - emergency (yes / No) "
