This map uses some of the imagery I discussed in my previous entry. Of note is that this map uses more of the river and creates a very unique design on the bridge.

Philly Quilt No. 2 by Nikolas Schiller

So I have yet to do so, but this weekend I plan on going through all my diamond quilt projection maps and re-categorizing them by rotation (0 & 45 degrees). I have yet to make any quilts that are wholly asymmetric. I have thought about making one or two, but for some reason I just don’t like the way they look. I guess it’s a sense of balance I am after and when I have one seam going horizontally across the page and add another seam that is 25 degrees rotated, it just looks awkward. I’d rather have clouds, than an asymmetric map.

As for this map, the seam makes an interesting reflection on the Pennsylvania Convention Center. What I also discovered last night, and is something I look forward to doing some more research on, is how there is a secondary texture that is being created in these maps.

When an aerial photograph or satellite image is taken there is usually some degree of distortion embedded into the orthorectified (defined as correcting distortions in an aerial image to produce a more accurate depiction of surface features) photograph. This distortion is usually caused by the angle at which the photograph was taken (directly above- nadir or at an angle- oblique). Thus if you take a photograph overhead at nadir (0 distortion at the center), then the buildings at the center will only show their tops, and the buildings at the edge will show their sides due to the angle of viewing. The interesting thing I discovered was the way the angles change with the seams. If you look closely at the details below, this angle creates an embedded texture of rotating the angle in which the buildings show. Essentially, its oblique alterations in the fabric of the quilt, and I think they make the tessellations even more intricate.

Finally I’ve gotten around to making some maps of Philadelphia. I had tried in the past, but when I downloaded the imagery I could never get the mosaic setup right. I wanted to make a large square of all of Philly to show both the Schuylkill and Delaware rivers, but I’d either not have enough imagery, or I’d screw up the download, or in the end, it just ended up being too large of a mosaic to incorporate into a tessellation.

Essentially, if my desired output size is 18,000 and my tessellated source imagery ends up being 9,000 X 9,000, then I am not going to be able to show all of the city because the seams cut out some parts at the center. Also, large tessellations take a long time to import and take longer to parse through when rendering. That is why I made 5 renderings for Philly! This is the first time I’ve made so many. One of them is also a nondescript highway intersection of 95 & 676, which I might use next (not sure!). As for this map, it’s the standard hexagon quilt projection with the western side of Philly showing. I chose to set up the tessellation so that the Schuylkill river was the geographic identifier and rotated the imagery around it. The result is nice and the river makes it easy to find the seams of the tessellation. Up next is a diamond quilt projection map rotated 45 degrees and it should look nice :-) This year I am going to continue making more diamond quilt projection maps!!
