So far I’ve made two other crosses: Mount Pleasant Cross and Memphis Cross. I am pretty sure how to make these now and future maps of this type will be added to it’s own special category on the sidebar. The cross above was chosen out of about 8 different tessellations and within this map is the National Archives at the center of the cross (hence the name), the Federal Trade Commission, the Robert F. Kennedy Department of Justice Building, the Federal Bureau of Investigation, the Navy Memorial- which features a map of the western hemisphere (below), the Winfield Scott Hancock statue, the Grand Army of the Republic Memorial, and portions of the National Gallery of Art Sculpture Garden and the west building of the National Gallery of Art, which make the vertical and horizontal stripe.

Newest Commission: Shirlington Quilt

I’ve been working on this commissioned map for a few months now. It was originally going to be Paris, but we decided to it would be easier to make a map of their house. I spent some extra time transforming the nearby highway into a heart (below) to signify the love between the husband and wife. I think it looks beautiful
It will be placed in the client’s home, which is featured within the map.

Saint Paul Quilt

It’s been quite a long time since I’ve made one of my signature quilt projection maps. On one hand I haven’t been inspired lately to make any new maps based on this technique. On the other hand, there are only a few American cities that I have yet to map, and Saint Paul, Minnesota was one of them. I was originally going to make this map during the Republican National Convention, but was sidetracked due to other work. Unlike the previous quilt projection maps that I have made most recently, which involved at least one recursive tessellation, this map employs the original style of my hexagon quilts.
This coming Saturday I will be in New York City for the New York Map Society’s monthly meeting. In preparation for my talk, I don’t expect to be blogging much this week because I intend on spending much of my spare time preparing my notes for the talk. If you are in New York, I hope you can make it!

Meridian Hill Park Hexagon Tessellation

This is the first time I’ve made a tessellation using hexagon as the basis for the pattern. Normally, I simply use a square because its the easiest to tessellate. The last map I made using Photoshop was Clayton Quilt #3, which was constructed using one square tile six times and did not exhibit radial symmetry like most of my other Qulit projection maps.
This time around I used center portion of the source tile that I used for Meridian Hill Park Quilt #4 and to switch things up a bit, I cut out a perfect hexagon from the the tile instead of using the tile’s square shape as basis for the tessellation. With one hexagon cut out, I merely duplicated it and moved it around to create the irregular tiling above. The difficulty was that I had to adjust the hexagon tiles so that they were not overlapping. It wasn’t that difficult per se, but it took awhile to get them all lined up perfectly. I am quite pleased with the result and figure that I will use this process again sometime in the not-so-distance future.

Meridian Hill Park Quilt #4

I’ve been doing some research on an old sculpture that used to be in Meridian Hill Park that will be featured in an upcoming posting. In preparation, I decided to make a quilt projection map of the park using the newest available imagery. Unlike the previous three, which were some of the first to use my recursive tessellation technique, the newer imagery captures less of the area surrounding the park and more detail of the park itself. This is simply due to the fact that the newer imagery has a high spatial resolution than the older imagery, which correlates to more detail, but less geographic coverage. Since the aerial photography was taken in the early spring, the fountains were still in their winter slumber and I imagine that if it were taken in the summer the coloration would be vastly different.
When constructing this map, I used my new technique hypothesized in May and first rendered a hexagon tile and then took a portion of that tessellation and used it here. The result, which I am seeing for the first time, is that you can see the hexagon shape around the center of this square quilt projection map quite easily. From my understanding, depending on the location of the recursive sampling within the first map, I’ll be able to see it’s respective geometry embedded in the second map. However, I think it’s nearly impossible to fully gage the geometry of the original map after two recursions because each subsequent sampling makes it more difficult to see the geometry present in the previous map.

New York Public Library Quilt

This fractal octagon quilt projection map was recursively rendered four times before the final result above. It took approximately two hours for each rendering to complete and then each tessellation was sampled while maintaining the source spatial integrity. Altogether this map took about 12 hours of rendering time and post-processing time to complete. I intend on printing this out for the upcoming lecture.

Madison Square Garden Quilt

Using my new procedure, I pre-rendered 2 tiles to create this third derivative map of Madison Square Garden in Midtown Manhattan. It looks very similar to Hirshhorn Quilt (they are both circular buildings) but they are composed of aerial photographs taken at different spatial scales. The NYC imagery has been downsampled to 2ft per pixel compared to DC’s imagery which is at 6 inches per pixel or a difference of about 16 times less detail (I think). Up next will probably be the New York Public Library, which was actually in the first tessellation, but dropped from the second.

Manhattan & Brooklyn Bridge Quilt

Yesterday I went through all my 2008 entries and began to compile this year’s maps like I’ve done for previous years. However, this year I decided to expand the listing to include designs & animations that I’ve made.
The rationale for this expansion was rather simple: if these yearly listings are to be aggregates of my creative work, they might as well include everything. I’m a bit tepid about going through the previous years to find creations that I might have missed, but I imagine that I’ll get around to doing it. Also, since this website has gone public, I’ve found myself sharing content that I did not create and this makes it more difficult to decipher what I’ve created and what I have found on-line & decided to share here.
Today’s creation is the start of a new series of New York City maps that I expect to make in the coming days. This morning I discovered that the USGS has released newer imagery of New York City that was taken in March of 2006.
However, as with other imagery, I’ve found that the older imagery is of better quality. Its not that this new imagery is fuzzy or not as sharp, but rather I found the coloration to be more subdued. The 2004 imagery, which I used to produce all of my previous New York City maps, is more vivid and the colors just look nicer. With that issue aside, I’ve made a few different tessellations that I’m going to be using for the next set of maps of New York City.
This map shows the Manhattan Bridge and the Brooklyn Bridge, as well as a tiny portion of Brooklyn and a larger portion of Manhattan’s Lower East Side. I tried a few different Quilt projection shapes and finally settled on using the Diamond Quilt Projection because I like the way the bridges create a square box within the diamond layout. I have made a derivative tessellation of this map, but I think I’m going to use some of the other imagery first.

A New & Arabesque Map of the Hirshhorn Museum & Sculpture Garden

:: saved at 6,480 x 5,040 ::
To celebrate the new procedure I decided to get around to editing the Library of Congress‘ copy of Willem Janszoon Blaeu’s Nova totius terrarum orbis geographica ac hydrographica tabula, which was published in Amsterdam in 1606. I removed the original map from the center and kept the decorative border similar to Nova et Accvratissima Totivs Terrarvm Orbis Tabvla, A New Map of the Terraqueous Globe : according to the the Ancient discoveries and most general Divisions of Geospatial Art, America as a Cloverleaf, and A New And Accurate Map of the World by John Speed. However, unlike the previous antique map mash-ups, which usually feature the earth laid out in two hemispheres, this map uses a rectangular space (Mercator?). The beauty of this open layout is that I can place any of my previously made maps inside of this 402-year-old template.
A common naming practice I’ve noticed in old map is the use of “New & Accurate” and since I like to play around with words, I changed Accurate to Arabesque to create a visual pun. The source map was about 6,500 pixels wide, I underlaid a rotated 9,000 x 6,000 copy of Hirshhorn Quilt to fit perfectly in the center of the new map. I think it would be fun to actually hand-color the engravings on this map to match other copies of this map which have the various figures colored in. The LOC’s copy is uncolored which means that its actually easier to add color to it than if it were already colored because pigment matching is not needed.

Hirshhorn Quilt

Following up on my new procedural idea from last week, I made this derivative map without publishing the intermediate maps. The unseen steps involve the rendering of a pre-Hirshhorn Quilt, sampling a portion of that quilt, and projecting the imagery again to create the map above. The result, as with all derivative maps, is a more symmetrical, arabesque map. This technique will be used again.

Swampoodle Quilt #3

Using this portion of Swampoodle Quilt #2, I constructed this derivative Diamond Quilt Projection map of the area around the 2008 Art-O-Matic venue in the Swampoodle neighborhood in Washington, DC.
After making this map I conceived an alternative procedural route to constructing future derivative maps. Those of you that have read this blog for awhile know that I do sequential maps, where you can literally see the visual process of what part of the previous map was used to construct the next map. However, this recursive process shows all the intermediate maps, when sometimes I just want to get to the final map. So the idea is to make smaller maps, like 12,000 x 12,000 (square not 3:2) and sample these maps first and not publish the intermediate maps. For example, I make a map of a new location and after processing that map, I sample it and render another map, sample that map, and render that map as the final map of the geography. The difference here is that I would not publish the intermediate maps as [City] Quilt #2, #3, etc. but just the final map. I’m going to try that next.

Swampoodle Quilt

I chose this site because it’s where Artomatic is at!
Swampoodle is an old name used to describe a small section of the H Street neighborhood in Northeast Washington, DC. The area was first settled in the 1850s by immigrants fleeing the Irish potato famine. A geographic approximation of its borders would be K Street to the north, G Street to the south, 1st Street NW to the west, and 2nd Street NE to the east. Through the center of it, just east of North Capitol Street, ran the principal branch of Tiber Creek, creating the low swampy ground from which the area took its name.
A few years ago developers created the North of Massachusetts Avenue Business Improvement District, or NOMA and have tried to rebrand the neighborhood to something different.
When making the map I concluded that at the time of the aerial photography’s acquisition, it was still called Swampoodle and not NOMA. The same goes for Google Maps, which shows an even older glimpse (from spring 2002) of the changing neighborhood.
Personally, I think the name Swampoodle gives the area character in name. In contemporary identity, the area is mostly a bunch of warehouses and parking lots that are about to be developed, so I look forward to seeing a Swampoodle map in 10 years. It will look drastically different and I just hope its not called some focus group-approved abbreviation of a geographic region.

North End Quilt #2

Using this portion of North End Quilt, I constructed this derivative Hexagon Quilt Projection map of the area around North End neighborhood of Boston, Massachusetts.
After rendering the map, while I was processing it for on-line publication on this website, I noticed that the source tessellation was off by one pixel and subsequently, this map has a slight defect to it. This is not the first time this has happened, but it makes me disappointed because the map is not perfect like the rest.

Boston Common Quilt

I’ve had a couple geographers contact me asking if I was attending the AAG’s annual meeting in Boston. My answer has been that I’m too busy on various projects to attend. As a former employee and someone who helped facilitate two annual meetings (Denver & Chicago), I realized that the next meeting I plan on attending will be as either an exhibitor or if the trip is paid for by an employer. I would like to give another presentation again or organize a panel discussion, but, as with most things in life, I’m in no hurry.
Since I have not made any maps of downtown Boston since August of 2005, I decided to download the city, in lieu of going to the city. Pleasantly, I was able to download the city at two different spatial scales and from two different years: 2004 & 2005. So far the imagery looks a lot better than the patchwork design that was previously placed into the public domain. Eight different tessellations later, the entire downtown area will be remapped in the next week. Today’s map features the area around Boston Common, which is the oldest public park in America (created in 1634), and the Massachusetts State House. I chose an Octagon Quilt Projection because I liked the way the center creates a compass rose. Up next will be a derivative of today’s map.

Saint Louis Quilt #5

This map of downtown Saint Louis, Missouri is the first to use imagery from 2006. I have now made maps of downtown Saint Louis that show the downtown area at three specific periods in time in the last 6 years. In the near future, I might made a montage of how the geography has changed using familiar portions of these maps. It think it would look very interesting. As I mentioned before, I like the way that I’ve been able to capture the Busch Stadium’s progression over time.

Albany Droste Quilt

I’ve made similar Droste-like maps before that are multi-scalar, but this is the first to follow “rules” involved in creating the Droste Effect. To achieve this effect I cut out an octagon out of the center of the map and pasted a 34% reduced duplicate of the map within the octagon. This recursive process allows for multiple internal repetitions because the source map is very large in size (216 megapixels).

Scott + Dupont Circle Quilt

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.

I find it quite interesting being able to see the difference between spatial scales when comparing the two previous Union Station maps. Since this map uses .16 meters per pixel aerial photography and the previous two maps use imagery that was .3 meters per pixel, you can quite easily see how much less I am now showing of the area around Union Station. Specifically, this map only shows the U.S. Postal Museum, Union Station, the Thurgood Marshal Federal Building, and the U.S. Securities and Exchange Commission.View the Google Map of Union Station in downtown Washington, DC.

Scott Circle Quilt

I am in the process of making hexagon quilt projection maps of all the major traffic circles in Washington, DC. I have most of the circles covered and intend on continuing this project as I acquire new imagery of Washington, DC. Of important note is that Dupont, Logan, Washington, and Scott circles all lie with the area that is censored in Google Maps. Also, this is one of the first maps that I’ve made in a few years that features National Geographic’s headquarters. I will probably make a derivative map dedicated to National Geographic.

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…
