Pearl Street Quilt
|| 6/8/2007 || 12:20 pm || Comments Off on Pearl Street Quilt || ||

A couple weeks ago my old friend from summer camp came and visited me here in DC. In honor of our 13 year friendship I decided to make a couple maps of the area around the Pearl Street Mall in Boulder, Colorado where he works as a bartender.

While the two maps might look almost the same, they are slightly different. They were created using two different tessellations of the exact same area, which is the same process that was used for the Beverly Hills maps. I also have the imagery of CU Boulder and will probably make that next.

University of Southern California Quilt no.2 by Nikolas Schiller

Read my brief comments about USC in my previous entry.

Of note, is that after posting the last map I looked at the number of maps I’ve made of Los Angeles and realized that I have enough for a 2008 Calendar! I will definitely put one together in time for this Christmas season. And after even further review, I actually have enough maps for a series of different calendars- DC, California, Texas, various universities, and fractals. :-)

Quilt of Charleston South Carolina
|| 4/1/2007 || 4:18 pm || Comments Off on Quilt of Charleston South Carolina || ||

: rendered at 18,000 X 12,000 :

I’ve waited for some time for this imagery to be released and I am somewhat disappointed that it was released at .6 meters per pixel (roughly 2 feet per pixel). This spatial resolution allows for more area to be covered, so the benefit was that I able to get most of the southern portion of the city covered.

On a different note, I’ve found a slight limitation with WordPress’ category naming system. For each map I’ve made a category for both the city and state, with the state being the parent category. Months ago I made a couple quilts of Charleston, West Virginia and I found that I could not add another category named Charleston because it technically already existed even though it was nested with West Virginia. I was thinking of naming the category “Charleston2” or “CharlestonSC,” but I haven’t yet. I will figure something out….

Polar Coordinates of Austin, Texas [square]
|| 1/18/2007 || 4:27 pm || Comments Off on Polar Coordinates of Austin, Texas [square] || ||


8 tiled map

I recently read through the work of Dr. Andrew Hudson-Smith (located at the Center for Advanced Spatial Analysis in London). I was intrigued by his use of Polar Coordinates to create panoramas and synthetic planets. I had been shown how to make the panoramas before, but I hadn’t actually figured out how I could incorporate my current work with this design technique. After some experimenting I figured out some interesting new methods to display tessellated aerial photography using the Polar Coordinates filter. The results are quite amazing and show definite promise for further research…

For this experiment I used the “zoom” of Austin Quilt #2 (a square quilt projection) as my test tessellation to begin working with. I could have used any zoom from any previously made map, but since it was snowing in Austin yesterday, I thought it would be ironic to use the Polar Coordinates filter.

The process to create the panorama planets is relatively simple:
– Stitch together series of photographs
– Reduce the panorama (by default a rectangle) to a square
– Apply Polar Coordinates filter in Photoshop

What makes my experiments unique is that instead of stitching together a photograph, I am I am stitching together perfectly symmetrical square tiles (composed of tessellated aerial photography) to create a rectangle. Moreover, I am maintaining perfect ratios throughout: 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, and 8:1. For example, the source tile is 800×800 and for each polar coordinate created (below) I merely added one more tile to rectangle ([1600, 2400, 3200, 4000, 4800, 5600, 6400]x800).

For each ratio there are three images shown below:
– Rectangle with number of tiles
– Conversion of the Rectangle to Square
– Application of Polar Coordinates filter

Note: The first image of each ratio below appears to reduce in size after each tile has been been added. In order to maintain a constant width on my website, I’ve chosen to reduce each rectangle to 800 pixels in width (otherwise this entry would be 6400 pixels wide right now!). When originally manipulating the rectangles they were not reduced in size. Essentially, it was done to show the scale of the panorama at a fixed width of 800 pixels.

I am excited about what directions this technique might take my cartographic activities :) My next experiment will be to see how the application of the Polar Coordinates filter will effect each geometry of the quilt projection. This experiment was conducted using the square quilt projection, up next with be the diamond. The results should be interesting.

I used .65 meter resolution from March 30th, 2003 and released to the public on October 1st, 2004. There was also .3 meter imagery available taken at a newer date, but I chose to use the older imagery because the download size would be smaller. More later….

This imagery of 2005 is not yet on Google Maps or Windows Live Local… hence seeing it here first is kinda like seeing what will be seen in the future, while actually seeing an interpretation of the recent past. Time is relative anyways.
