About eHealth Africa - West Africa Project Countries
Polio in Nigeria – Brief Background
 Highly infectious viral disease, which mainly affects young children
 Polio is a crippling and potentially fatal infectious disease
 There is no cure, but there are safe and effective vaccines
 The strategy to eradicate polio is therefore based on preventing
infection by immunizing every child until transmission stops and the
world is polio-free
 Nigeria now confirmed to be Non-Endemic by WHO

eHealth Africa And FOSS4G
 Project initially started on proprietary software
 Need to for technology transfer to Government
 Need to concentrate on capacity development
 Need for community support
 Need to integrate other open data and software applications

Vaccine Direct Delivery
 Purpose: Effective last mile vaccine delivery to health facilities to support routine
immunization
 Reduces stock-outs, eliminate late supply and damage due to high temperature
Cold Store
Parent Facilities
Child Health Facilities
Methods:
Health Facilities and Zone classification, cluster
creation, drop order, time window, FIFO
Cascade mapping
 QGIS to define routing procedures
 OSRM to produce batch routing
 OSMAnd to monitor driver routes and behaviour
Zone (LGAs)
Cluster
(driver catchment)

Vaccine Direct Delivery
Interactive Batch Routing - Currently used for Vaccine Direct Delivery Routing

Telecommunications Signal Mapping
 Purpose: Understand health facilities with strong, poor or no mobile network
coverage
 Method: Passive Data Collection, Data processing, Data analysis and Web
Application Development
 Data Collection – Crisis Signal App
 Data Storage – PostgreSQL (PostGIS)
 Data Processing – FME (Feature
Manipulation Engine)
 Visualization: CartoDB
Use cases
 Health worker communications, Disease
Surveillance, Vaccine Delivery
Telecommunications Signal Mapping
Current Developments and Challenges
 Migrating Internal geodatabase
operational processes to Open Source
 Building Open Source Versioning and
Replication Environment
 Building Oslandia QGIS versioning plugin
- https://github.com/Oslandia/qgisversioning
Current Developments and Challenges
 Deploying OpenStreetMap Platform and osmosis
 Customizing our CKAN platform - building analytics and user management
into CKAN
