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

Current State of GIS Technical ArchitectureHybrid model which connects together ESRI ArcGIS
technologies with Free & Open Source GIS Software (FOSS4G) in an integrated environment
eHealth Africa Open Source GIS Architecture
▪ Web services are made available through APIs
QGIS PostGIS
Portal(CKAN)
Desktop GIS Files
Enterprise Database
Distributed Web services
Web GIS (MapServer/GeoServer)
Custom Analysis and Visualization to support custom requirements
Data Sharing Portal deployed on CKAN, fetching data from PostGIS and Publishing data in ESRI Shape, CSV, GeoJSON, WMS and WFS
• Web Editing Service (TinyOWS)• Web Feature Services (WFS) • Web Mapping Tile Service (WMTS) – Image tiling• Web Mapping Service (WMS) – JPEG, PNG• Batch Routing Service (OSRM API)
Web Services
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
Health Facilities and Zone classification, cluster creation, drop order, time window, FIFOCascade mapping
Methods:
Cold Store Parent Facilities
Child Health Facilities
Zone (LGAs)Cluster(driver catchment)
Health Facilities
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
QGIS to define routing procedures
OSRM to produce batch routing
OSMAnd to monitor driver routes and behaviour
Vaccine Direct DeliveryInteractive Batch Routing - Currently used for Vaccine Direct Delivery Routing
More on routing - Check out Kehinde Adewara at 16:25 Room 12, B1F, K Avenue
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
