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
