The other week I downloaded the aerial photography of downtown Birmingham, Alabama to make some maps for a friend of mine. Upon closer inspection of the geography, I found that there was a nicely formed highway interchange close to the downtown area that happened to be colloquially named “Malfunction Junction.” While other cities can also claim in having their own Malfunction Junction, this highway interchange is the first one I’ve read about.
When I started working on this map I intended to render a couple versions and recursively sample them to created a fractal map, but I wasn’t happy with the results, so I decided to go in a completely direction. This map did end up using previously sampled imagery, but it does not conform to that regular quilt projection format of a centralized kaleidoscope. Also, this map is not unlike some of my previous maps, like White House Sunrise or Minneapolis Sunset, however, I chose to name it differently based on the position of the kaleidoscope’s focal point, which is offset in the upper left hand corner. I spent a lot of time adjusting this location and as you can see in the last detail below, I was a few pixels off. Up next I’m probably going to work on the downtown area of Birmingham, but I’m really itching to start mapping Europe.

Digital Globe: Where did DC’s roads go?

Screen grab featuring DC with very few roads
I was looking at Digital Globe’s website the other day and I decided to zoom into Washington, DC. The result was a map that only shows the major highways around the area. What is missing, however, are all the roads in DC, even the ones that connect to the “major highways” outside of the District. While the roads are not really needed to find locations of imagery, I’ve come to the conclusion that this is a good example of how an on-line mapping environments can leave out a lot more content than what should be included. Since this map environment was designed to seek Digital Globe’s imagery, not highways, it would make more sense that the base layer shows archive satellite imagery and not ugly vector graphics that incompletely show the major transportation routes in DC.
Notice:
– Two different city centers: Washington + Washington, DC
– In the margin map, the star next to Columbia is not District of Columbia, but South Carolina
– In the margin map, all cities are capitals as well
– Gallaudet University is the only university shown
