Trying out new GIS software

October 2, 2010 / / 0 Comments

I want to draw 50 and 120 feet buffers around the points of store entrances to show where bike parking should and shouldn’t be installed. I want to follow this example:

walgreens with bike parking buffers

Aerial photo of a Tucson, Arizona, Walgreens showing the location of existing bike parking and two buffers (50 and 120 feet) where proposed city rules would allow bike parking. I advocate for ratifying the 50 feet rule, which I’ve discussed on this blog and elsewhere many times.

I want to do this easily and accurately, so I will use GIS software to create a “buffer.” I use QGIS occasionally, but I want to try out other Mac-friendly applications. I’m getting my orthoimagery (geometrically corrected aerial photography) from the United States Geological Survey (USGS) using a web protocol called Web Map Server. I’m trying:

  • Cartographica, $495, with free trial license.
  • uDig, completely free software. UPDATE: I have had NO success getting any data to load from a WMS connection into uDig. I would like to understand why. Cartographica can obtain some of the WMS-stored data I want, although it messes up often.

I’m having success with neither – both are having issues downloading or maintaining a connection to the USGS orthoimagery. In one case, Cartographica trims the Bing Maps imagery to match the extent of my other objects (the buffer). In another case, it won’t even download the USGS imagery (and gives no indication that anything is happening). uDig hasn’t been able to download anything so far – I hope it’s asking for the current extent, instead of all data because it’s taking a looong time to do anything (so long that I just quit in the  middle of it).

This screenshot shows how to add new WMS connections to Cartographica.

UPDATE: I did it! I successfully used Cartographica (and the integrated Bing Maps) to create this drawing that shows the current (abysmal) bike parking at a Chicago Home Depot outside the 50 feet line.

Bike parking distance being put to test in Tucson

October 1, 2010 / / 0 Comments

Work is underway to implement strict (but appropriate) rules about where Tucson, Arizona, businesses must install bike racks. This news comes from Tucson Vélo. It first came to my attention in May when I was creating and expanding my definition of Bike Parking Phenomenon A, which I now call the “50 feet rule.”

3 of4 bikes are parked on hand rails within 20 feet of this Seattle Whole Foods entrance while one bike is parked more than 50 feet away at the City-owned bike rack.

I left this comment on yesterday’s article from Tucson Vélo:

“Distance is more key to bike parking usage than the quality of bike parking fixture. Bicyclists prefer to use an easily removable sign pole that is closer to final destination than lock to a permanent bike rack further away.”

Some businesses there are complaining that devoting room in front of their business to bike parking removes space available for selling goods. I encourage everyone to support rules requiring bike parking within 50 feet. If installed further away, it simply will go unused.

I’ve written about distance parking many times:

After new bike racks were installed within 10 feet of the Logan Square Chicago Transit Authority entrance, no one parks at the original spots. See how the foot makes a difference?

Departing under the best conditions

September 28, 2010 / / 0 Comments

I was reading a brochure and timetable (yes, we still call them that) about the TGV Lyria high-speed train service from Paris to cities in Switzerland. Someone left it on a counter at work. It’s in French, and I can read about half of it.

The timetable asked that travelers board the train at least two minutes before the departure, “pour assurer les départs TGV Lyria dans les meilleures conditions” (to ensure the train departs in the best conditions).

Two minutes? You only have to find your train 2 minutes before departure time?

Short story: Back in 1998 (I was 14), my mom and I were traveling from Paris to London on the Eurostar (travels under the English Channel). We’re walking down the ramp to the platform and one of the conductors sees us coming. He yells or motions for us to hurry up. We start jogging down the ramp and jump into the nearest car door.

About 45 seconds later, the train leaves.

More about being on-time:

  • 87.8% of TGV Lyria trains were arrived on time in June 2010.
  • 76.% of flights from 24 reporting airlines arrived on time in the same month. (U.S. DOT)

Heard of the Great American Streetcar Conspiracy?

September 23, 2010 / / 0 Comments

General Motors and Standard Oil bought up the country’s streetcar systems, replaced the routes with buses, and thus began America’s automobile love affair and distaste for mass transit.

Streetcars are being now being rebuilt all across America, including in Portland, Oregon.

Heard that before?

Before you perpetuate it further, read this essay for some perspective on the story. Apparently, it’s a problem only liberals suffer from.

Even today it resonates with liberals – The Atlantic casually mentions it as the reason America abandoned mass transit, The Nation wrote a whole article about it a few years ago, Fast Food Nation discusses it, and in the last week I’ve seen two references to the theory in the planning blogosphere.

Now, this essay still isn’t the “end all, be all” chronology of transportation evolution history in the United States.

The new(ish) streetcar in Portland, Oregon.

Do you know of a book or article where the writer summarily presents concrete evidence? The essay does cite four academic sources, so it’s the best explanation of the so-called conspiracy I’ve ever read.

I’m bringing this up thanks to Edward Russell, who posted it, and my sister, who mentioned it to me after a friend told her about the story.

New York City, a dreamland

September 20, 2010 / / 0 Comments

Rather than write a lengthy post here describing my recent trip to New York City (I went in the last weekend of August), I will invite you to peruse my 50 photo gallery. They are in order by date and time taken and fully mapped and described.

I was last in New York City in August 2001, for the MacWorld Conference where I saw Steve Jobs announce the iPod – I got that iPod for Christmas that year. I stayed in Connecticut. The first day, my dad and I drove into the city. The next day we took Metro North from Bridgeport. The only thing I remember doing on that trip is taking the subway from the Javits Center to the Hard Rock Cafe and over to Grand Central Station.

I’ll describe my 2010 trip as a “whirlwind tour.” In three days I rode over 100 miles on a too-small borrowed bike. I met fourteen people. I went up and down the island four times. I wouldn’t shut up at work about it for a week.

The first photo in the set, about the typography of the New York City yellow cab system.

The last photo in the set, about pedestrian craziness in the segregated bike lanes.

Full photo set. The set is sure to grow, so stay tuned to my Flickr photostream or Twitter feed for updates.
