5. 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

6. Geodatabase Nigeria Geodatabase Layers
Administrative Boundaries – Wards (2,814), LGAs (774), States (37, including FCT)
Health Facilities: > 20,000+
Settlements: > 146,000+
Built-Up Areas: > 8,500
POIs: > 300,000
Roads: > 500,000 Km

7. Current State of GIS Technical Architecture
Hybrid model which connects together ESRI ArcGIS technologies with Free & Open Source GIS Software (FOSS4G) in an integrated environment

8. eHealth Africa Open Source GIS Architecture
Web services are made available through APIs
Custom Analysis and Visualization to support custom requirements
QGIS
PostGIS
Portal
(CKAN)
Web GIS (MapServer/GeoServer)
Distributed Web services
Desktop GIS Files
Enterprise Database
Web Services
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)
Data Sharing Portal deployed on CKAN, fetching data from PostGIS and Publishing data in ESRI Shape, CSV, GeoJSON, WMS and WFS

9. 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

10. Data Sharing Data Portal and Web Mapping Platform Web Map Platform
Data Portal:

11. OpenStreetMap OpenStreetMap States We’ve Mapped Kano Kaduna Katsina
Sokoto

Bauchi

12. 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
Zone (LGAs)
Cluster
(driver catchment)
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

13. Vaccine Direct Delivery
Interactive Batch Routing - Currently used for Vaccine Direct Delivery Routing
More on routing - Check out Kehinde Adewara at 16:25 Room 12, B1F, K Avenue

14. 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

15. Telecommunications Signal Mapping

16. Current Developments and Challenges
Migrating Internal geodatabase operational processes to Open Source
Building Open Source Versioning and Replication Environment
Building Oslandia QGIS versioning plugin - versioning

17. Current Developments and Challenges
Deploying OpenStreetMap Platform and osmosis
Customizing our CKAN platform - building analytics and user management into CKAN
