Google Maps, the dynamic GIS system

Earlier this year, Google Maps added a feature to the common maps interface that allows users to identify problems* with map data or presentation. Click on the “Report A Problem” link in the lower right corner of the current map view. Then drag the marker on top of the error, categorize it, then write a description of the problem.

I reported several problems soon after the feature was released. I checked up on the results of one problem I reported. The situation was the lakefront multi-use path along Lake Michigan in Chicago, Illinois. The screenshots below show the map before I reported the problem and the repaired map.

With this addition, Google Maps seems to be encroaching on the territory of Open Street Map (OSM) that uses ONLY public domain (not the same as free) and user-contributed data. But the data users contribute to Google Maps (in the form of reporting problems on the map) become the property of Google and its data providers.

From the OSM Wiki, “The copyright of the whole data set is scattered among all contributors. Some contributors release their contributions to the public domain.” Readers interested in learning more about maps in the public domain should read this Guardian article about the UK’s Ordnance Survey heavy grip on its data.

Disclaimer: I felt prompted to write this post because James Fee on his blog often (1st) writes (2nd) about the (low) quality of the data Google puts in its Maps.

*Users have long been able to report problems, but never in such an easy way or one that tracks reports and notifies the user when Google fixes the error.

Tuesday roundup: Getting around

These are the posts about “getting around” I found interesting today. Blogs and the links to the referenced articles are in bold.

“Nowhere does transportation happen for transportation’s sake.” – Professor DiJohn, UIC.

Discovering Urbanism

Have you ever noticed from an elevated train or an airplane the dirt paths and small trails through parks and vacant lots? Like water and electricity, people travel the path of least resistance, with or without a dedicated facility. (Is that why flooding’s so difficult to control?) In the most recent “Google Earth Travelogue,” Discovering Urbanism points out the innumerable walking paths in the quarter mile park or mall between two highways and building corridors in Brasilia, the master planned capital of Brasil. Selected quotes:

I added this comment about how planners can use this “route choice theory” (path of least resistance) to determine where to install paths for bicyclists: “Where should cities build bikeways? Where people want them. And how might we figure where people go, aside from a stated answer survey, we could tag 1,000 random bicyclists with GPS and track where they go. It would probably give us an image like the second one in your post: with yellow lines criss-crossing the city’s street network.”

Jennifer Dill’s study of Portland, Oregon, bicyclists did just that! She asked, “How does the built environment influence bicycling behavior; and what routes did they take?” The project wasn’t used to determine where routes should be built, but how existing routes affect trips. I think the same data the project collected could also be used to answer my question, “Where should cities build bikeways?”

Human Transit

The City of Minneapolis, Minnesota, is in the midst of a major transportation upgrade in downtown. They’re converting one-way streets to two way streets with bike lanes and off-peak parking. What a way to “unlock downtown,” says Human Transit.

And they tripled bus capacity on new transit malls with two regular travel lanes in one direction, and two bus-only lanes in the opposite direction. The malls also mixing in staggered bus stops, or groups of stops targeted at a specific area of the city, making “service more legible.” Selected quotes:

  • “…every bus was as slow as the slowest bus.”
  • “Doubling the width triples the capacity.”

I visited Minneapolis in September to explore the Midtown Greenway and Hiawatha light rail. I also rode my rental bike through downtown to get a feel for how another Midwestern city’s downtown lives.

The Transport Politic

Dubai seems to grab way more headlines than its Persian Gulf neighbor, Qatar. But Qatar, with the fastest growing economy on Earth, has decided rail (both passenger and freight) infrastructure is a “crucial element to economic viability.” Some might say the Dubai Metro heavy rail transit line is too late to battle congestion (Reuters). Can Qatar avoid the same fate?

The plan the Qatari government signed with Germany’s Deutsche Bahn is ambitious: “The project will incorporate 180 miles of local light and metro rail for Doha city center, rapidly expanding public transportation offerings for what is now a car-centric place.” Selected quotes:

  • “Deutsche Bahn is laying its reputation — and its money — on the line for this project, which will be its largest-ever foreign investment.”
  • “If a country is defined by the spending it commits to its future, the U.S. is falling behind rapidly.”

I don’t think the United States will start comparing itself it to any Middle Eastern country anytime soon – many in this country still think Iraq was involved in the September 11, 2001, terrorist attacks.

Fietsen in Nederland (bicycling in the Netherlands)

If you and I have chatted about bicycling in the past six months, I’ve probably mentioned the Dutch in our conversation.

Why?

I want a Dutch bicycle. Explaining this one will take another blog post – compiling all my reasons takes a long time. But in addition to cool bikes, here’re a couple other things they do:

  • They (the Dutch) make bicycling better (safer and easier). More people ride their bikes than drive cars for a majority of trips. They have the lowest cycling injury and fatality rate.
  • They build bicycling infrastructure beyond what I can imagine. Bike highways connect small towns and big cities. 4,000 space parking garages.

I started reading a blog called “A view from the cycle path” written by Briton David Hembrow living in The Netherlands. He writes about bicycling history in the country, posts ridership statistics, discusses his commute, and sends readers to more information about it all.

I also read Marc van Woudenberg’s blog, Amsterdamize. I found it either via Flickr, or via web search, when I looked for other WorkCycles Fr8 owners and users. I want the Fr8 bike (pictured below). I can get one from the local WorkCycles (build their own bikes and sell other manufacturers’) dealer, Dutch Bike Chicago.

Remind me to post my paper and presentation about the past, present and future of bicycle planning in The Netherlands I will submit for my Sustainable Development Techniques class at UIC.
