Continuing my current project of mapping the portions of Washington, DC that Google is censoring, I decided use the same process that was used to create Washington + Dupont Circle Quilt. This type of digitally derived double exposure aerial photography creates some of my favorite maps as of late. While I am only touching on the germane juxtaposition of traffic circles in Washington, DC, I’ve been thinking about how I take two completely disparate geographies and create similar styled maps. One idea is to take two of the tessellations I created for the Los Angeles Interchanges Series and create a double exposure highway interchange. Another possibility is to make a Supreme Illusion Supreme by overlaying the Pentagon on to the site of the World Trade Center. I’m not sure how it would look, but I think I’ll try making one of these maps in the near future.

Washington + Dupont Circle Quilt

I decided to switch things up a bit with today’s rendering. I have become very efficient with most of the processes used to create my maps, which both makes them standardized and sometimes a bit too similar to each other (while paradoxically being different geographies). This map and probably the next few maps are going to be slightly different.
In order to have the most recent maps of Logan Circle, Dupont Circle, and Washington Circle look similar to each other, I would take the first derivative tessellation and overlay it on top of the tessellation that I was constructing. By adjusting the transparency, I can overlay the circles directly on top of each other which makes the subsequent map look nearly identical.
Normally, I simply delete the original tessellation when I have the two lined up perfectly, however in today’s map I chose to not delete the other map. Instead, I adjusted the transparency of Dupont Circle to 51% to show both geographies at once. The result is something that I wasn’t expecting, but am quite pleased with the results. I can see myself using this process again. It’s like a double exposure…

Poor Map Design: 5 Guys Famous Burgers & Fries
The other day I was at Five Guys getting lunch and I picked up their to-go menu (below). On the back of menu was a completely blank page with the map above. When I saw it, I laughed out loud and said, “This has got to be one of the worst maps I’ve seen in awhile.” At least my grilled cheese sandwich was tasty..
Let me explain:

Dupont Circle Quilt 2005 #2

After making yesterday’s map, I thought it would be interesting to expand on the “sister circle” concept and make a similar version of Dupont Circle. The process involved in making this map is something I have never done before. I took the source tile from Logan Circle Quilt #2 and reduced it to the original 3,000 x 3,000 size and opened up Dupont Circle Quilt 2005. Once the opened, I overlaid the source location on to Dupont map and tried my best to place it on the exact same location. This involved an attempt to overlay the circles on top of one another. The assumption was that they were the same in size, so by adjusting the opacity of Logan Circle, I was able to fit them on top of eachother. Of course it wasn’t exact, but what it allowed me to do was to copy the same location and create a very similar tessellation. I know it wasn’t perfect because the circle is slightly truncated when overlapped. You can see this (below) in the way that the fountain does not show up properly. Regardless, I am really pleased with the way the new process turned out.

Dupont Circle Quilt 2005

In continuance of my current task of mapping the areas of Washington, DC that Google has chosen to censor, I decided to revist my favorite circle.

Dupont Circle Quilt #2

As I learned before, its always better to over-project than to under-project, however there is a caveat to over projection- that being my computer can handle files that are below about 25,000 pixels. I have gone higher, but in the end, I can’t fit the final compressed output on to a CD easily. So why make something so large that I cannot feasibly back it up? That’s why I’ve chosen to stick to the 18,000 by 12,000 file size. The trick to the over projection process is to make sure that the tessellation (source imagery) appears in the scene the appropriate number of times, and if not, I scale the scene so that the final product will be as close to 1:1 as possible.
Alas, I really like this map, and I think the next one, which uses the already rotated source imagery, will look great!

Dupont Circle Quilt

I used one of the smallest tessellations yet to make this. The source imagery of the tiled Dupont Circle was only 2,600 pixels, but I made the right calculations to keep spatial resolution very similar the final product the same as the source (I counted how many times I saw the full tiled go across and multipled by 2,600). I like how it turned out, but I wish there was more merging of the circle itself, as in the circle itself would become a larger circle around the center.
Up next, I am going to make one using nothing but imagery of GWU
