By sampling the previous map in this series, I was able to construct this Dodecagon Quilt Projection map. I have prepared imagery for a forth iteration, but I’m in no hurry to render it.
One interesting observation that I can extract from this series is that the imagery that is currently being used as the source material is of better quality than what is currently viewable on Google Maps and Google Earth. I’ve found the capitol dome to be a bit washed out on their imagery.

My Artist Talk At The Old Print Gallery

Yesterday, Friday, October 15th, I gave an artist talk at the Old Print Gallery in conjunction with my exhibition. The screen grab above is from a special opening slide that I made for the talk. Its the first HTML page that I have used the auto-refresh tag. It was designed to cycle through different maps every 10 seconds before the lecture began. I might add this feature to the front page of the website now that I see that it works. The talk lasted a little over an hour and included a brief Q & A at the end. Thank you to everyone who came.
Below are the “slides” that I used for my presentation and most are hyperlinked to their original entries:
A T-Rex Google Map On My Neighborhood Via Twitter

The other day I allowed Twitter to track my location. Much to my chagrin, the map that was created looks awful. At first I thought it looked like PacMan and now I’ve come to the conclusion that it looks like T-Rex, and that ‘T’ stands for Twitter.
Washington Monument Quilt #2

When the 2005 USGS aerial photography was released to the public in the spring of 2007 there were a few places that were censored through pixilation. On this blog I documented how the White House was censored. I documented how the U.S. Capitol was censored. And I even experimented with a QR-Code to show that the Washington Monument was censored. After doing some exploration within the newly obtained 2008 Washington, DC orthophotography, I discovered that the White House and the U.S. Capitol are STILL censored.
However, now that the construction of the new visitors center at the Washington Monument has been completed, which is the reason, I am told, why the Washington Monument was originally censored in the 2005 imagery, the imagery of the monument is now available without pixilation. Moreover, its the exact same imagery that is being used on Google Maps. While I expect to showcase the censorship of the White House & U.S. Capitol in some future entries, I decided to make make my first map of this new dataset of the Washington Monument because I wasn’t able to make it using the last batch of imagery.
To construct this map, I first rendered a full-size Hexagon Quilt Projection map using the original imagery, then sampled a portion of the resulting map, and used the sampled portion to create this derivative map. I chose to sample the portion in the first map because of two underlying aspects of the map. First, I really liked the way the shadows of the Washington Monument combined together. Secondly, I liked the way the apex of the Washington Monument was combined (see detail below) to create a pyramid. Over the years I have enjoyed playing with the notion of aerial & architectural chiaroscuro, as in, using shadows generated by buildings within the original aerial photography to create a new, larger shadow. This map embodies this ongoing design element perfectly.

Google Maps: Add the Contour Interval to the Legend of your Terrain maps
|| 8/6/2009 || 3:56 pm || 5 Comments Rendered || ||
Nearly every printed topographic map I’ve ever looked at has the contour interval, otherwise known as the distance between contour lines, listed in the legend. Depending on the scale of the map, the contour interval ranges from 1 foot to hundreds of feet between each successive contour line. The contour interval allows the map reader to instantly know the relative steepness & flatness of the topography in the map at one quick glance. Because of this crucial information, a topographic map is considered incomplete when it does not disclose this information to the reader.
Enter the Terrain feature of Google Maps. Released to the public in November of 2007, the contour lines were subsequently added in April of 2008. I hadn’t really given the feature much use until last week when I was planning my weekend excursion to the Shenandoah mountains. I was trying to figure out the altitude variation on my friends property by finding where their property line started & ended and calculating the elevation change. Since their property lies on the side of a mountain, I wanted to know the altitude at the bottom of the property and the altitude of the highest portion of the property, and subtract the difference to find the total elevation variance.
What I found out instead was that Terrain function of Google Maps was lacking the contour interval declaration in the legend. As with all their maps, the lower left-hand corner showed the units of distance on the map, but was missing the topographical information provided by the contour interval declaration.
In lieu of ever getting a response from Google Maps after previous queries, I decided to send a tweet to Google Maps:
I wasn’t really expecting a response, but a couple hours later I received this response on Twitter:
Before & After Aerial Photographs of Ground Zero in Nagasaki, Japan

I was looking at the Wikipedia entry on Aerial Bombing of Cities and came across the World War Two aerial photograph above. It shows the absolute destruction of the Nagasaki, Japan after the atomic bomb known as “Fat Man” was dropped from the sky and detonated in the heart of the city. Below is a screen grab from Google Maps showing a contemporary view of ground zero:
…from life to death to life… Its rather amazing how much development has taken place since the war ended over 60 years ago. I just hope this type of bombing never happens again.
Dear Yahoo! & Navteq, it’s not the National Msm of the American Indian!
|| 7/13/2009 || 3:49 pm || 1 Comment Rendered || ||
Back in March of 2008 I discovered that Google Maps was incorrectly displaying the official title of the National Museum of the American Indian on their maps. They had truncated the word museum to MSM. A friend of mine who works at Navteq, the supplier of the data, confirmed that the length of the title was too long, so they shaved off a few characters by truncating the word museum to msm. This lexical error was eventually corrected on Google Maps….
However, last night I had someone in India do a Yahoo! search for National Msm of the American Indian and ended up visiting my page. Upon closer inspection, I discovered that Yahoo! Maps was also doing the same type of truncation with Navteq’s data. I think NavTeq should to change it’s dataset so all the museums names are spelled correctly.
Note: the links in the images in this entry go to the Hirshhorn Museum & Sculpture Garden because it was the closest result for my query “National Msm of the American Indian”
The aerial photography of the area around the Metro crash site contains a Metro train
|| 6/23/2009 || 11:10 am || + Render A Comment || ||
Like the highway collapse of I-35 in Minneapolis, the partial collapse of the MacArthur Maze, the destruction of Hurricane Katrina, and the Columbine shootings, I’ve decided to make a map of the area around yesterday’s Metro crash site. Earlier today I downloaded the imagery of the site and found something I wasn’t expected. Not far from the actual crash site there is a Metro train on the tracks. While its not as interesting as the Ghost Cars on the I-35 bridge, I found it interesting that of all the locations for the Metro train to be when the plane flew over in March of 2005, the Metro train happens to be VERY close to the actual site of the tragedy.
Note: Google Maps currently uses the same USGS imagery that I am using.
Google Map Mashup: The Qibla Locator
|| 4/20/2009 || 10:54 am || 1 Comment Rendered || ||
Following up on yesterday’s posting, I stumbled across this interesting Google Map mashup. The Qibla (or Kiblah or Qiblah or Quibla) is the Arabic word for the direction that should be faced when a Muslim prays, otherwise known as the direction of the Kaaba in Mecca. For obedient muslims, the Salah, or formal prayer, is performed five times a day: at dawn (fajr), noon (dhuhr), in the afternoon (asr), at sunset (maghrib) and nightfall (isha’a). The Qibla Locator is a simple Google Map that is designed to automatically orient Muslims toward the direction of the Kaaba. Simply enter your location and the red line that is generated shows the shortest distance to the Kaaba. In the case of the screen grab above I decided to show what direction a Muslim would pray if they were in the White House in Washington, DC. I chose this location because I’ve read about some nutty folks who actually think president Barack Obama is a Muslim. Frankly, I don’t care what religion he practices and to take issue with anyone’s religion is a sign of intolerance and veiled ignorance. What I find most interesting about the Google Map is that the rhumb line toward the Kaaba can be somewhat deceiving. I’m not blaming the author of the mashup, rather, I think the nature of how the Quibla is found is unique. Since its based on the shortest distance to Mecca, sometimes the fastest way seems counter-intuitive, as in, I was thought the path from the White House (above) would be facing South-East instead of North-East. If you have a moment, try it out.
A couple interesting notes from the Wikipedia entry
• The head of an animal that is slaughtered using Halal methods is aligned with the Qibla.
• Muslims are buried with their faces in the direction of the qiblah. Thus, archeology can indicate a Muslim necropolis if no other signs are present.
A short history of the Qibla:
Originally, the direction of the Qibla was toward Masjid al-Aqsa, Jerusalem (and it is therefore called the First of the Two Qiblahs). At least since Mishnaic times (AD200), Jews face the Temple Mount in Jerusalem while praying. The Mishnah speaks about this in Berakhot (Talmud) chapter 4, Mishnahs 5 and 6 and this practice is even found as early as I Kings 8:35-36. In Islam, this qiblat was used for over 13 years, from 610 CE until 623 CE. Seventeen months after Muhammad’s 622 CE arrival in Medina, the Qiblah became oriented towards the Kaaba in Mecca. According to accounts from the prophet Muhammad’s companions, the change happened very suddenly during the noon prayer in Medina, in a mosque now known as Masjid al-Qiblatain (Mosque of the Two Qiblahs). Muhammad was leading the prayer when he received revelations from Allah instructing him to take the Kaaba as the Qiblah (literally, “turn your face towards the Masjid al Haram”). According to the historical accounts, Muhammad, who had been facing Jerusalem, upon receiving this revelation, immediately turned around to face Mecca, and those praying behind him also did so.

Thomas Jefferson’s Map of Washington from March 31st, 1791
|| 2/28/2009 || 1:30 pm || + Render A Comment || ||
Throughout the week I watched the Senate debate on the District of Columbia House Voting Rights Act of 2009. This bill (which I’ve written about before in its different forms) will give DC residents a token vote in the House of Representatives, while denying us representation in the Senate. (Taxation Without 2/3’s Representation!!) Thursday afternoon the Senate passed the Act after they also voted to add a bogus amendment written by the National Rifle Association to weaken/remove the District of Columbia’s gun laws. The vote showed clearly that the District of Columbia is still Congress’ little colony and even with the Act’s passage, DC residents are no better off than before, except of course, we’ll be governed by 536 unelected officials, instead of 535. Hurrah for continued tyranny masked as progress!
There were two words I heard over and over again during the Senate debate: Founding Fathers. Thomas Jefferson, the third president of the United States, is revered as one of America’s founding fathers and after looking at his map that he drew in 1791 (and attempting to read his nearly illegible text), I’ve come to the conclusion that the Seat of Government that the Constitution gives Congress exclusive jurisdiction over (Article I, Section 8, Clause 17), is also nearly the same geography that was defined as the National Capital Service Area [link to Google Map] when DC statehood was proposed. This area is basically all the federal government buildings around the National Mall and is what I feel Congress should have exclusive control over. So why was the Seat of Government expanded to include the entire District of Columbia when Jefferson clearly drew a smaller vision 218 years ago? I don’t know, but fixing one of the Founding Father’s faux-pas should involve giving DC residents full equality that citizens of the rest of America receive, which means representation in both the House and the Senate.
