Open Source GIS stack: data Hub for flexibility, performance and effectiveness.
Nicolas Gignac, Public Safety Quebec & eHealth AfricaFrank Salet, eHealth Africa
Plan● GIS Data sharing needs● Why choosing FOSS4G?● The case of Nigeria● The case of Quebec in Canada● Opportunities of partnership
GIS Data sharing needs● Access to data in multiple and open format● Multiple datasets as the formal source● View and analyse data on-demand● Reduce unnecessary data replication● Benefit from platform of the open data community● Access data in a standardised way● Minimise the use of ETL● Good & simple metadata documentation to find quickly the
right data without technical assistance● Data can be quickly access with both GIS proprietary and
open source software
Why choosing FOSS4G● Linked to standard (OGC) and open data movement (OSM) : (Nigeria & Quebec)● Freedom and flexibility in development (Quebec)● Multiplatform (Linux, Windows) (Nigeria & Quebec)● Getting support from community (Nigeria & Quebec)● Invest in HR instead of licence fee (Quebec)● Good for HR development (Nigeria & Quebec)● Multiple solutions linked together, not a one-solution-fits-all (Nigeria & Quebec)● Free to install and deploy (Nigeria & Quebec)● Fast & reliable on the server-side (Quebec)● Well adapted to cloud hosting and Software as Service (Nigeria)● ...
The case of Nigeria● Use case present earlier at FOSS4G-Asia (Yesterday)● eHealth Africa : Supporting polio eradication programme since
2011 and Ebola outbreak response ● US NGO using technology to give health service in Northern
Nigeria● NGO is supported by external private funds & support from WHO● IT Development towards open source (GeoDjango, FormHub,
tablet apps) ● GIS is more an hybrid model (ESRI+FOSS4G)● Hired as GIS International Consultant to help their 20 GIS staffs for
a short term project and FOSS4G training
GIS implementation at eHealth● Support ESRI licences by funding● ArcGIS-ArcMap used for editing● Uses MS SQL Server for database and versioning● Support by OpenStreetMap - Humanitarian Team (HOT)● FTP transfer from database to Health applications● Expensive licences and versioning with ESRI complex● ArcGIS Rest not performant for ETL needs or cascading need● Stack of open source tools develop for none-GIS apps by IT Team
(GeoDjango, PostgreSQL, OpenData kit, FormHub, Salt, nginx)
FOSS4GIS implementation at eHealth● JOSM, HOT-OSM Tasking Manager● Batch routing with OSRM● Start editing layers in QGIS● Multiple map services on AWS using :
○ PostgreSQL-PostGIS: DBMS○ MapServer: WMS & WFS cascading○ CKAN: Catalog, data portal and metadata○ OpenLayers+Geoext+ExtJS: Web viewer
● GIS Internal Windows Server using :○ MapServer (WFS cascading) serving MS SQL Server data○ MapProxy: imagery donated by partners
● OGC standard use (WMS, WMTS, WFS as GeoJSON or CSV)
GIS Architecture at eHealth
GIS data published by eHealth
Catalog and data released ODbL licence available: http://data.ehealthafrica.org/
GIS web viewer (OpenLayers+ExtJS+Geoext): http://gis.ehealthafrica.org/eHealth/ehaloc/
The case of Quebec (Canada)● Need flexible, open, not costly and reliable 24/7 GIS service solutions● Focus over data on-demand, integration, analysis and publish on the
web● Flow of information and data support decision in disaster management● Since 2008, Quebec Public Safety used and involved in GIS open
source (MapServer, OpenLayers, PostGIS), open data (GeoNetwork) and open standard (WMS, WFS)
● Use standard (OGC member, OASIS) to be interoperable with other GIS system (ESRI, Hexagon- GeoMedia) used by multiple partners (private, public, NGO, citizen)
The case of Quebec● Public Safety developed from 2009 to 2013: Web
GIS Service (800 layers) and apps using 100% FOSS4G
● 6 others organisations merge together sharing: source code, web service, infrastructure, development process, expertise and documentation to create: IGO, meaning Open GIS Infrastructure.
The case of Quebec
The case of Quebec● IGO has multiple components:
○ Web GIS viewer: XML file config○ Layer tree Manager and security: XML file & database
configuration○ Editing tools based on WFS-T, but as GeoJSON service○ Spatial Analysis Service - WFS & WPS with Zoo project○ Routing Service - OSRM with gov data○ Metadata Service - GeoNetwork - PostgreSQL○ Geocoding Service - as PHP Service - SOAP
The case of Quebec● IGO is an API on top of JavaScript & Phalcon● IGO has a data security model liked on GeoPrisma● IGO depends on UMN MapServer, but can act as a WMS
client● XML config on top of OpenLayers two, GeoExt 1.0● Adapted to change backend libraries (OL3, Leaflet) without
XML change● Made also for integration in web site/portal as iframe● IGO is an API based on MVC (Model-View-Controller) ● Planned to be open source in 2015 as LGPL licence
The case of QuebecIT Environment :● Ubuntu 14.04 LTS, CentOS● Security : LemonLDAP & Apache● DBMS: PostgreSQL\PostGIS, Oracle● FOSS4G : MapServer, OpenLayers, MapCache, PHP (Phalcon), GeoExt,
ExtJs, JQuery, OSRM, Zoo project● Standard: WMS, WFS, CSW, WMTS, WPS, SOAP and CAP● Cascading: WMS & WFS of partners services (close to the source)● GDAL/OGR (ETL)● Gitlab & Redmine (forge)
The case of Quebec
The case of QuebecIGO Governance (based on UMN MapServer Community) :● 7 Ministries main contributors● 15 organisations as users● Other potential organisation4 levels of partners:
- Contributors- Committers- Technical committee- Management committee
Possible partnershipseHealth: public health, mobile technology, OSM data, Software as a service, cloud [email protected]
Quebec Public Safety: involve in IGO when code release, disaster management, FOSS4G, web standard, web spatial analysis, community-based development for government/municipality [email protected]
