Mississauga Data Adds KML to the Open Data Formats

Mississauga Data is releasing new data sets towards a more open approach.  We will be releasing datasets in a format called KML.  Many computer software mapping applications can display KML, including Google Earth, Google Maps, Google Maps for mobile, NASA WorldWind, ESRI ArcGIS Explorer, Intergraph GeoMedia, Adobe PhotoShop, AutoCAD, and several others.  Read about KML format on WikiPedia (

Mississauga Data is planning to release the following data sets in KML format:

  • Multi Unit Residential Housing Inventory
  • Natural Areas Survey
  • Vacant Lands Inventory
  • 2010 Mississauga Employment Survey (a sample of the top 100 employers)
  • 2010 Existing Land Use Survey
  • New Planning Districts, now called Character Areas in the New Official Plan
  • Office Inventory (planned for late 2011 release)

It’s Easy:

  1. Download & install Google Earth or any other software of your choice
  2. Download the KML data file you want to visualize from our Open Data Catalogue (
  3. Double click on the data file to open it!

Why Open Data?

  • It is easier for citizens and companies to make decisions about locating in Mississauga by making this data freely available and easy to use
  • Provides a far more detailed and interactive picture than we could ever provide in a traditional hardcopy or PDF format map
  • It is actually more efficient for us to release this information in a geographic format (such as KML) versus spending significant effort preparing traditional reports/printed maps
  • A move towards a self serve model by providing closer to raw data
  • By updating this data more frequently, combining it with other data sets we would hope that a community of open software applications grows out of this initiative and provides further benefits back to our taxpayers.  Other large cities such as: Toronto, Vancouver, Calgary, Edmonton, NYC, and San Francisco have already adopted Open Data.  Read more about Open Data at:
