<p>The data for countries other than the US is hard to obtain, and were it not for the tremendous effort the folks at <a href="http://geonames.org/">geonames.org</a> put into collecting it, these maps would not have been possible. That data is somewhat less reliable than the US one &ndash; having said that, however, <a href="http://www.monte-bre.ch/">Marc</a> (the guy behind geonames.org) has been extremely responsive and fixed several problems that became apparent when drawing the maps. Misplaced points and mismatched names become quite apparent when a line is protruding into another state or province, or far into the ocean. So these maps actually have some use, after all. The shape data for drawing country outlines was obtained from <a href="http://www.vdstech.com/map_data.htm">VDSTech</a>, but there seem to be many other sources for them.</p>
<p>The maps below are available as (large) PNGs and as PDFs for printing. There are several versions for each country, depending on how useful the short names for states that were included in the data appeared. And even though postal codes are not called ZIP codes outside of the US, I will stick to the name for the nice ring it has.</p>
<p>Want more maps? I will keep collecting data (and I have data for a few more countries), and post new maps as sufficiently reliable and complete data becomes available. If you have data about postal codes that contains latitude/longitude information, or can somehow be linked to it, please <a href="http://eagereyes.org/contact">let me know</a>.</p>
<h2>Australia<a name="Australia"></a></h2>
<p>The data for <a href="http://en.wikipedia.org/wiki/Australia">Australia</a> is apparently incomplete, though I don't think we're missing much. Even if you are not very familiar with Australia, you will perhaps realize that the map is missing <a href="http://en.wikipedia.org/wiki/Alice_Springs%2C_Australia">Alice Springs</a>, which is smack in the middle of the continent. A few other cities are missing, too. But overall, the structure is very believable.</p>

<p><strong>Austria</strong><a name="Austria"></a></p>
<p>Though the data for <a href="http://en.wikipedia.org/wiki/Austria">Austria</a> still seems to have a few small problems, the overall structure looks like many of the other maps. The pattern in the far north of <em>Nieder&ouml;sterreich</em> (Lower Austria, N) is remarkable though, because it looks different than the rest. Also, Vienna (W) is lacking some data, but would look like a spiral connecting its districts otherwise. What is quite visible, though, are the mountains that define the borders between some of the provinces, and which appear as regions without any postal codes.</p>

<p><a href="http://en.wikipedia.org/wiki/Canada">Canada</a> is the second-largest country in the world in terms of area, and is also extremely sparsely populated.

<h2>France<a name="France"></a></h2>
<p>The <a href="http://en.wikipedia.org/wiki/France">French</a> are know for their beaurocracy, and the map seems to be an expression of that. Inside each <em>r&eacute;gion</em>, there are several clusters for the <em>d&eacute;partements</em>, neatly separated. Smaller departments are often thrown together with larger ones, though, and inside each cluster is a nice bit of scribble chaos to make things more interesting. To the south-east, you can see the Mediterranean island <a href="http://en.wikipedia.org/wiki/Corsica">Corsica</a>.</p>

<h2>Spain<a name="Spain"></a></h2>
<p><a href="http://en.wikipedia.org/wiki/Spain">Spain</a> has an interesting internal structure in terms of postal codes. Rather than a lot of chaotic scribble, many of the lines do not cross over, a bit like on the <a href="http://eagereyes.org/Applications/ZIPTPCMap.html">Travelling Presidential Candidate Map</a>. The only excaption is Galicia (GA), with its very dense scribble structure.</p>
<p>In order to get a compact image, I had to move the <a href="http://en.wikipedia.org/wiki/Canary_Islands">Canary Islands</a> to the north and east. This is indicated on the map. In additon, you can see the <a href="http://en.wikipedia.org/wiki/Balearic_Islands">Balearic Islands</a> to the east, in the Mediterranean. The little spot directly south of mainland Spain is <a href="http://en.wikipedia.org/wiki/Melilla">Melilla</a>, a Spanish possession in north Africa. Interestingly, Spain's other exklave <a href="http://en.wikipedia.org/wiki/Ceuta">Ceuta</a> does not seem to have a Spanish postal code.</p>

An interactive version is also in the works.<!--break--></p><p>The biggest headache were certainly the two missing states. While finding map data for the states was not all that hard, moving Alaska without completely distorting it was another thing entirely. I put a lot of work into this update, and can&#39;t invest any more time right now. I will, however, add a map of all the states at a later time. </p><p>I did add a backdrop that shows the outlines of the states. Printing a thin gray line did not work very well on the printers I tried, so I opted for the area rather than the line approach. The lines are only just visible, but that was my intention - I did not want to make them stand out too much. The coloring is already quite strong. </p><p>The issue with coloring neighboring states with the same color in two instances was solved by adding a little interactivity to my program so that I could cycle through colors for a state, and and save all the colors once I was satisfied with them. This was certainly much less work than implementing a graph coloring algorithm, but not because of that algorithm, but because creating the graph of neighboring states does not appear to be all that straight-forwward. Since states don&#39;t change much, I am happy with this approach. </p><p>I also changed the projection several times, and am now back to a Mercator projection, which has its center in the center of gravity of all the ZIP points. This appears to be pretty well in line with many other maps you see, though there is some variation. Note the straight border with Canada now.</p><p>Maps for other countries are certainly high on my priority list, but this is made difficult by the fact that location data for postal codes is very hard to obtain for places other than the US. The fine folks at <a href="http://www.geonames.org/">geonames.org</a>  have done an incredible job collecting that (and a huge amount of other) data. This is still limited to relatively few countries though, and then to the ones where there is enough precision in the data to make a decent map. Right now I have usable data for Australia, Austria, Canada, France, Germany, Italy, the Netherlands, Norway, Spain, and Switzerland. I have a few more datasets, but these are not yet in a state where they produce believable images, and even some of the ones listed above contain visible errors. Still, the mere existance and availability of that data is a minor miracle, and I am quite happy with the results. </p><p>For an interactive version of the map, I experimented a bit with Google Maps. The problem is that it just can&#39;t handle overlays with so many points, it only works reasonably well for very sparsely populated countries like Canada and Australia. I will therefore make my program into a Java applet, and put that on here. This is going to take a bit more time, but should happen before the end of January. </p>    ]]></content>

So I had the idea of using a <a href="http://en.wikipedia.org/wiki/Hilbert_curve">Hilbert curve</a>  to get an approximation. A Hilbert curve is a recursive space-filling curve that provides a linear path through all locations in a square. Here is one level of it, in the next level each line segment is replaced by a more coplex curve, etc. </p><p><img src="http://eagereyes.org/media/attachments/HilbertCurve.png" alt="Hiblert Curve" title="Hiblert Curve" width="311" height="312" /></p><p>I was <a href="http://www.nirarebakun.com/graph/ehilbtsp.html">not the</a> <a href="http://www.idynamix.org/_pmath370FinalProj/index.html">first one</a>   to have the idea of using a Hilbert curve for this task, and the existing work shows that this solution is typically only 75% optimal. But that is good enough for my purposes, and it proved quick enough to implement and run a rather naive implementation of (about 10 minutes on a 1.67GHz Apple PowerBook). </p><p><a href="http://eagereyes.org/media/attachments/ZIPTPCMap.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPTPCMap-thumb.jpg" alt="Travelling Presidential Candidate Map" title="Travelling Presidential Candidate Map" width="600" height="338" /></a> </p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPTPCMap.pdf" target="_blank">Travelling Presidential Candidate Map PDF</a>) </p><p>The Travelling Presidential Candidate Map (TPC) does not look nearly as interesting as the ZIPScribble. There are hardly any crossing lines, which makes the image appear a lot lighter and less interesting. It also loses quite a bit of the information in the original map, which nicely showed the borders between clusters of ZIP codes, which also defined state borders.</p><p><a href="http://eagereyes.org/media/attachments/ZIPTPCMap-color.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPTPCMap-color-thumb.jpg" alt="Travelling Presidential Candidate Map Color" title="Travelling Presidential Candidate Map Color" width="600" height="338" /></a> </p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPTPCMap-color.pdf" target="_blank">Travelling Presidential Candidate Map Color PDF</a>)</p><p>It does gain from adding more information though, like coloring the states. Its slightly flimsy appearance does not change, however. The thin lines also make it harder to see the colors, especially in the small &quot;thumbnails&quot; on this page. </p>  <p><a href="http://eagereyes.org/media/attachments/ZIPTPCMap-color-names.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPTPCMap-color-names-thumb.jpg" alt="Travelling Presidential Candidate Map Color with Names" title="Travelling Presidential Candidate Map Color with Names" width="600" height="338" /></a></p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPTPCMap-color-names.pdf" target="_blank">Travelling Presidential Candidate Map Color with Names PDF</a>)  </p><p>Finally, the map with the added borders to better see where the path crosses state lines.

So off I went on a little programming exercise to see what simply connecting the dots would do.  </p><p><a href="http://eagereyes.org/media/attachments/ZIPScribbleMap.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPScribbleMap-thumb.jpg" alt="ZIPScribble Map b/w" title="ZIPScribble Map b/w" width="600" height="350" /></a></p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPScribbleMap.pdf" target="_blank">ZIPScribble Map PDF</a>) </p><p>The patterns and density distribution are readily apparent, and can in fact be seen much better than when only the dots are drawn. The scribbling quality of the lines (looks like somebody was bored while talking on the phone) lead to the clever name for the map. So let&#39;s enhance the map, and see if those apparent borders are in fact state lines or just artifacts. </p><p><a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-thumb.jpg" alt="ZIPScribble Map color" title="ZIPScribble Map color" width="600" height="350" /></a> </p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color.pdf" target="_blank">ZIPScribble Map Color PDF</a>) </p>Not surprisingly, some of the white lines really separate states, others don&#39;t. For the non-US folks (like yours truly), it makes sense to add state names for better readability, and also to disambiguate some problems with the rather simplistic coloring algorithm.<br /><p><a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names-thumb.jpg" alt="ZIPScribble Map color, names" title="ZIPScribble Map color, names" width="600" height="350" /></a>  </p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names.pdf" target="_blank">ZIPScribble Map Color with Names PDF</a>) </p><p>Adding the colors clearly adds information, but it also removes some of the mystery. The scribble quality is much more apparent from the monochrome version (nobody has lots of differently colored pens lying around). The colored version looks more interesting, but also looks much more like any other map than the monochrome version.</p><p>Since the lines between the denser areas could still be artifacts, let&#39;s add a backdrop to see if they really are state lines. </p><p><a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names-borders.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names-borders-thumb.jpg" alt="ZIPScribble Map Color Names Borders" title="ZIPScribble Map Color Names Borders" width="600" height="350" /></a></p><p align="center">(<a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-borders.pdf" target="_blank">ZIPScribble Map B/W with Borders</a>) (<a href="http://eagereyes.org/media/attachments/ZIPScribbleMap-color-names-borders.pdf" target="_blank">ZIPScribble Map Color with Borders PDF</a>)</p><p align="left">As some of the comments below have mentioned, Alaska and Hawaii are missing from this map. Here are these two states, they will eventually be included in the map above, and also a PDF of them will be available.</p><p><a href="http://eagereyes.org/media/attachments/ZIPScribble-AKHI.png" target="_blank"><img src="http://eagereyes.org/media/attachments/ZIPScribble-AKHI-thumb.jpg" alt="ZIPScribble of Alaska and Hawaii" title="ZIPScribble of Alaska and Hawaii" width="600" height="272" /></a> </p><p>Is this visualization? Sure, because it shows data. The pictures are not interactive (though I am working on an interactive version to put here), but they do allow some insight into the patterns created by the numbers. Is it useful? Probably not. But it sure is surprising and interesting, rather like a fractal image.</p><hr /><p>See also the <a href="http://eagereyes.org/Applications/ZIPTPCMap.html">Travelling Presidential Candidate Map</a>.</p><p>Stefan Zeiger has produced a <a href="http://szeiger.de/zipmap/">ZIPScribble Map of Germany</a>, and also a map of area codes.</p><p>Updates 1/3/2007: changed projection, higher resolution images, added borders backdrop, improved coloring, added AK and HI. <a href="http://eagereyes.org/blog/improved-zipscribble-maps-more-countries-to-come.html">More details here</a>.</p><p><a href="http://eagereyes.org/Applications/MoreZIPScribbleMaps.html">Maps for a dozen more countries</a>  are now online.</p>    ]]></content>
