Parking Lot Map

 The Parking Lot Map is a project of the Parking Reform Project, an organization dedicated to climate action, safer streets and housing affordability. The map explores how much land in the central area of the major cities of the United States is dedicated to parking. On average 20% of land is dedicated to parking (this does not include the land dedicated to streets and highways). In Columbus that number is 27%.

The map interface is simple and effective-red parking lots on a gray background. There is a pick list where you can choose a city. Some cities have a "view more" button where you can get zoning details. Here is a map of the Columbus Parking Overlay District.

At the bottom is a graph ranking the cities.

The bottom entry is Arlington, Texas with 42% of its downtown dedicated to parking. The lowest non-suburban city is Las Vegas with 32% of its land as parking. 

Some people would argue that a parkable downtown is a good thing and the cities at the bottom should be considered the best places but charming old European cities like Paris aren't universally loved for their ease of parking. 

The best cities on the list tend to be older ones built out before cars. Washington D.C. only dedicates 3% of its downtown area to parking.

However there are plenty of exceptions. Detroit, the motor city, dedicated 30% of its downtown to parking.

Thirty Day Map Challenge - Part 3

Here is the final batch of maps for the #30DayMapChallenge. The first ten maps are here. The second installment here.

Day 20 -  Theme: Movement

The first plane trip I ever took. PHL to HOU with an hour layover in Atlanta.

Day 21 -  Theme: Elevation

I learned that you can make quick elevation profiles using Google Earth Pro and was curious what the Finger Lakes, some of which are very deep, would look like. Most of the work was in annotating the hills and valleys.

Day 22 -  Theme: Boundaries

At my day job I was asked to emulate a project from  the City of Columbus. When I first encountered that crazy boundary I didn't know what I was looking at but here it is. Many cities such as Detroit and Los Angeles surround well known enclaves but I've never seen anything close to this. Had some fun with the magnifying glass on the locator map.

Day 23 -  Theme: Data Challenge 3: Global Human Settlement Layers (GHSL)

Like many, I was completely unfamiliar with this data set. I still don't know much about it but I downloaded their built-up areas and drew them as if they were elevation, hills being the settled areas. I looked around for a good pattern and found Quebec City. In retrospect, I could have done a better job lightening the greys and changing the elevation quotient but there's only so much time in a 30-day challenge. I played around with some additional data layers in GIMP to create this image.

Day 24 -  Theme: Historical Map

I did some recent tutorials on how to create a historic looking map in GIS software.  The least historic place I could think of was Las Vegas. I got the buildings layer from the City of Las Vegas upon which I discovered that the main strip (including the casinos) is not even in the city but rather in Paradise, Nevada. Unable to find their buildings, I drew my own. I added an ad for wagon lumber. The text was inspired by other maps from that era. The title block was taken from a map of Las Vegas, New Mexico via the Library of Congress. Some image manipulation was used to change "N.M." to "NV" and the elevation from 6,400 feet to 2,000.

Day 25 -  Theme: Interactive Map

I enjoy hockey so I was curious about the world's second major league, Russia's KHL. Without reinventing the wheel, I made a similar interactive map to my previous ones of transit tokens and for New Year's Eve. Wikipedia was extremely helpful for providing both an already usable data set and the team logos. Above is just a screen shot. The interactive map can be seen here.

Day 26 -  Theme: Choropleth Map

For anyone that doesn't know the jargon, a choropleth is a map with areas colored based on data. In this case I tried my hand at a bivariate (two data variables) choropleth. This was based on a Tweet from the European Commission showing the relationship between COVID-19 vaccination rates and death rates. These maps can be hard to follow but the expected pattern should be yellow (low death rates, high vaccinations rates) to dark blue (opposite). The lack of red or orange shows that countries with high vaccination rates do not have high death rates. The confusion of the map is compounded by needing to flip the legend so that the high vaccination rates are at the bottom of the legend.

Day 27 -  Theme: Heat Map

It took 27 days but I finally thought to reuse a data set and made a heat map of Day 25's KHL data. I did not love the look of the original map (below) so I tried to hand draw it. It looks sort of nice but I misplaced the Moscow area and had to make up for it by adjusting some of the other locations. Here is the original computer generated version.

Day 28 -  Theme: The World is not Flat.

Once again working with the KHL data I tried my hand at a spherical map projection. This data is good for this because of the impressive longitudinal reach of the league. Those players do some long traveling!

Day 29 -  Theme: NULL

Going back to the theme from Day 26, I noticed that certain countries routinely had null data values for their vaccinations. Here they are.

Day 30 - Theme: Metamapping Day

I thought it would be fun to use this theme to show the locations and software used for my other 29 maps. However, the wheels came off the bus or I ran out of gas or some metaphor. I had numerous unexpected technical problems and finally just had to throw up my hands and put this mess out there. A couple of days got buried in the data or otherwise lost, the legend needs work and the US inset map is almost unreadable. 

This has been an excellent learning experience. I can't imagine going through this again which means I'll probably be back at it next November.

I highly recommend checking out other people's entries into the #30DayMapChallenge. There is some beautiful and wonderfully creative stuff out there.

Columbus O

I love this map dearly and could have sworn I already put it on this blog but I can't find any record of it.

The audacity of it all! A world centered on a giant "Columbus, O."

In one sense this is just simply a type of polar azimuthal projection map centered on Columbus. Perhaps the uncredited publishers in 1902 did not have any more an imperial intent than that. I prefer to think this as some good old over the top boosterism. I like the very oversized Scioto River and the bold language of the title.

Though coal fields and gas fields are prominent in the title, they are a little subdued on the map.

Also, the 70 mile radius seems wrong until you realize that each blue circle is another mile and notice how much they bunch up at the edges, where the towns are maybe a bit less "tributary" to Columbus.

The inner city detail is nice too.

There do not appear to be any additional details about who made this unusual map and for what purpose, but it's fun to explore and you can do that here

Random Thursday-Maps You Probably Won't Use Today

Have I mentioned that I don't really care for google (or bing or yahoo) maps? Sure they serve certain purposes very well and I even use them at work when they fit the bill. However, when directing me to your business I prefer a customized map. Here are some examples.

A map to the Kipu Ranch on Kauai where you can enjoy scenic beauty by ramming through it on an ATV.

Directions to Camp del Oro in Nevada City, California. You will probably get lost.

Raffles, an Asian restaurant in Nagoya, Japan. An Asian restaurant in Japan? What an idea!

The Book Loft of German Village - Columbus, Ohio. Absolutely not to scale but emphasizing the important details - and you can't do that in google!

Pasquia Regional Park in Saskatchewan- looks like it was drawn by a kid with cartographic skills.

A very red map of the locations of the Big R Stores in the Northwestern US. I love how the topography ends at the Idaho border!

Here's a map to The Strand - a development in Datarang Sunway, Malaysia. I got the image from Three Meals of Goodness, a Malaysian dining blog. I like the exaggerated earth curvature, and the Ikea.

Crap of the Week

John Krygier, a professor of Geography at Ohio Wesleyan University and DIY Cartography blogger created the Crestview Road Dog Sh*t Map for his street in Columbus, Ohio. It's kind of ugly but makes a point and I like the little steaming pile symbols. These days I pick up piles like that daily but obviously many dog owners don't bother.

Here's another crappy picture I stole from one of his blog entires - the NY City street grid in grout. OK enough bathroom humor, maybe next week we'll return to "cleaner" subjects. We'll see.
