More information overload please

A few months back, Microsoft made a presentation on OData at PHP Quebec. While I found the format interesting at first, with the way you can easily navigate and explore the dataset, I must admit I was a bit skeptical. After all, public organizations handing out their data to Microsoft does sound like a terrible idea. While a lot of that data will be hosted on Microsoft technologies, the format remains open, and it appears to be picking up.

I guess what was missing originally for me was a real use case for it. The example at the presentation used a sample database with products and inventory. Completely boring stuff. Today, at Make Web Not War, I had a conversation with Cory Fowler (with Jenna Hoffman sitting close by) who has been promoting OData for the city of Guelph. I got convinced right away that this was the right way to go. Not necessarily, OData as a format, but opening up information for citizens to explore and improve the city. If OData can emerge as a widespread standard to do it, it’s fine by me. The objective is far away from technology. In fact, when I look at it, I barely see it. It’s about providing open access to information for anyone to use. How they will use it is up to them.

The conference had a competition attached to it. Two projects among the finalists were using OData. One of them created a driving game with checkpoints in the city of Vancouver. They simply used the map data to build the streets and position buildings. That is a fairly ludicrous use of publicly available information, but still impressive that a small team could build a reasonable game environment in a short amount of time. The other project used data from Edmonton to rank houses based on the availability of nearby services, basically helping people seeking new properties to evaluate the neighborhood without actually getting away from their computer.

This is only the tip of the iceberg. The data made available at this time is mostly geographical. Cities expose the location of the various services they offer. The uses you can make out of it are quite limited. I’ve seen other applications helping you locate nearby parks or libraries. Sure, knowing there is a police station nearby is good, but there could be so much more. What we need is just more data: crime locations, incident reports, power usage, water consumption. Once relevant information is out there, small organizations and even businesses will be able to use it to find useful information and track it over time. At this time, a lot of the data is collected but only accessible by a few people. Effort duplication occurs when others attempt to collect it. Waste. Decisions are made based on poor evidence.

So there is information out there for Vancouver, Edmonton, even Guelph. Nothing about Montreal. Nothing in the province of Quebec that I could find. I think this is just sad.

Actually, if there is anything out there, it might be very hard to find. Even if there are these great data sources available openly, it remains hard to find them. There is no central index at this time. Even if there were, the question remains of what should go in it. Official sources? Collaborative sources? Not that there is anything like that, but consider people flagging potholes on streets with their mobile phones as they walk around. Of course, accuracy would vary, but it would serve as a great tool for the city employees to figure out which areas should become a priority. There are so many opportunities and so many challenges related to open data access. I don’t think we are fully prepared for the shift yet.

  1. @LP – You would be surprised how a small effort could be quite rewarding. I encourage you to go out and talk to your municiple government to see if they have current plans to start releasing open data. To give them an example, ottawa has released a few datasets quite recently [].

  2. I’m not surprise that Montreal isn’t showed there. In map data, Quebec is alone without the rest of Canada (and it’s right also for the langage). I work since more than 10 years as geomatical technician. All government maps coordinates are based on a special datum that we are alone to use. We also use special scale factor who suppose to give more accurate data(!). Yes, conversion is possible between datum. But it’s an extra step that generic map software don’t care. Some tools are developped to handle these extra steps but are unfamiliar to english users (because above all they are programmed in French) and then, they are not widespread. Yes, Quebec is a leader in geographical development and research. But money is not there to expand bright idea.

    Louis-Philippe argued he don’t know where to get Canadian and Quebec maps data. I refer you to the Quebec Atlas of Ministère des Ressources Naturelles du Québec where you can get free Quebec geographical data.
    For Canadian Map, I refer you to this link:
    Both web sites are completly hidden in government appliance. I suppose that a better public campaign (and a better domain name) could put these data more accessible.

    As general discussion about OData, I think that this revolution will start with map end users, not with professionals. I keep in mind my reaction when I took aware of OpenStreetMap. Yes, it’s a fantastic idea to share geographical informations and data. But, as a professional user, I prefer to used GoogleMaps data because this information can be used right now, even if I have to paid. I don’t want to wait 10 years to get it.

    But, I’m not closed to open geographical data format. I own that I program with PostgreSQL ans its GIS extension (PostGIS) instead traditional Oracle Spatial Database. And I almost alone in Quebec. But to understand how it work in Open Source project, I have to remember that I must compiled PostgreSQL and PostGIS with Cygwin (under Windows) when I started to use them about 6 years ago. It was the Stone Age. Now, both are distributed with Windows installer.

    PostGIS ( is made by Refractions Research, a company based on Victoria, BC. Those programmers make a fantastic work that can be looked at on They are closed to the Open Geospatial Consortium ( In my opinion, it’s the central point of open geospatial data. I didn’t hear about Microsoft OData. Maybe it will be another link on the chain. Maybe it’s good. Maybe it will be enough promoted to be claimed by both end-user and professional user. I don’t know for the future.
