MPS Geobase● Objective:
Provide a uniform geobaseto all stakeholders
● 300+ data layers (imagery and vectors)● 1.5 TB● Data sources:
● Government● Cities, Municipalities● Health● Private companies (e.g. utilities)● OpenStreetMap

OGC Web Map Service (WMS) Protocol
● Portrayal Service● Returns map images for a given request:
● LAYERS: name(s) of layer(s) to draw● FORMAT: GIF, PNG, JPEG, ...● WIDTH, HEIGHT: image size● BBOX: geospatial extent● CRS: coordinate system● STYLE: optional, rendering style
● Does not transport the raw data● VERY widely supported
1212
OGC WMS Benefits
● WMS Data Services can be reused by partner organizations in their own application
● Partner organizations can make their own data available to MPS via WMS
● No copies: data is always fresh from the source
● WMS is Portrayal only: raw data not exposed, solves some licensing and political headaches

G.O.LOC Portal
Geobase G.O.LOC
1414
G.O.LOC Portal
● For 9-1-1 centers and emergencyresponse people
● Web based: no software to install● Quick and simple to use● Provides access to the whole Geobase (WMS)● Can also access partner data (WMS)● Can easily be customized for specific use
cases

G.O.LOC Portal
● Web application based on OSGeotechnologies:
● OpenLayers● GeoExt/ExtJS
● Connects to● OGC WMS data sources (internal and
external)● MPS Geocoding Service
• Leverages the “Adresses Quebec” database
1616
1717
G.O.LOC portal
● 10 Partner Organizations● 35 9-1-1 Centers● 1000-2000 geolocation requests per day● ~500 internal users● ~500 external users

S.A.G. for 911 Centers
S.A.G.(Autonomous
Geographic Service)
1919
Autonomous Geographic Service (S.A.G.)
● Designed for 911 centers and emergency response teams
● Includes G.O.LOC and all Geobase layers (WMS)
● 100% open source software ● OpenSUSE Linux, Apache● MapServer, PostgreSQL/PostGIS,
GDAL/OGR● OpenLayers, MapFish, GeoExt, etc
2020
Autonomous Geographic Service (S.A.G.)
● Completely autonomous:● All software and data is local● Does not rely on any external
data source● Not vulnerable to:
• Power failures• Internet downtime or slowdown• Downtime of an external data provider
● Can be deployed in local mode to any PC or server in case of emergency

Partnership Example
Quebec National Institute for Public Health
2424
Quebec National Institute for Public Health
● Partnership with MPS for the sharing of● Development resources● Software components● Common source code repository (SVN)● Data layers
2525
Quebec National Institute for Public Health
● System for Real Time Surveillance of Extreme Meteorological Events Impacts on Public Health
● First application: Heat Wave Surveillance and Decision System
● Tested in real life during the July 4-8, 2010 heat wave
2626
Quebec National Institute for Public Health
● Inputs:● Meteorological data and public warnings ● Health Data● Air Quality● Geospatial Data
● Automated Surveillance System (alerts)● Decision System (maps, etc)
2727
Quebec National Institute for Public Health
● Software:● Web Mapping portal shares several
components with G.O.LOC● 100% open source● Uses OGC Standards
2828
Quebec National Institute for Public Health
● System deployed June 1st, 2010● July 4-8, 2010 Heat Wave:
● July 5: system started reporting alerts● Regions started deploying action plan early● Statistics show +30% mortality variation● In previous episodes (1987 and 1994), the
variation was over 100%
2929
● The Open Source “MapServer stack” and Open Standards (OGC WMS) are mature and robust technologies
● They are used in real life around the world● They helped save real lives, at least in Quebec
