The Wilkinson Microwave Anisotropy Probe, or WMAP, was sent into space by NASA to record the background cosmic microwave radiation of the universe. Last month the mission released “the first detailed full-sky map of the oldest light in the universe.” Detailed, perhaps, but you won’t be finding the earth or even the solar system on this one. WMAP’s website has a number of interesting maps of the universe and animated globes as well as a simple explanation of what the map means.
Wartime Leicestershire has a couple of maps used by the Germans during their bombing of England in 1940 - 1941. The two maps of Leicestershire are at a scale of 1:10,000 and appear to be copies of Ordinance Survey maps of the time. Also on the site is a map of the county indicating the location of bomb drops.
edushi.com is an interactive Chinese site that displays maps of various Chinese cities. The interface is much like the interface found on Google Local with a zoom toolbar in the upper right and a drag and pan functionality. Nothing unusual there. What makes this site interesting is how the maps look. Instead of a standard map or satellite image, an oblique representation of the street layout, along with 3 (technically 2.5) dimensional looking buildings, is provided, lending the site a rather SimCity-like feel.
Over on the GISuser weblog, Glenn complains about the lack of maps showing the results of Monday’s election results in Canada. I took up the challenge and produced a couple of maps, showing the winning parties and the percentage of the vote the winners garnered (image at left). For comparison sake, I've included a similar map for the 2004 election (image at right). Not the greatest maps but a quick indication of the changes in the political landscape in Canada. Higher resolution images are available on request (ccablog@yahoo.ca).
According to CNN, a Mexican government commission will distribute 70,000 maps “showing highways, rescue beacons and water tanks in the Arizona desert to curb the death toll among illegal border crossers.” The commission is denying that such a move would encourage illegal immigration to the United States but others are not so convinced. The maps were designed by Tuscon, Arizona-based Humane Borders whose site hosts a number of border-related maps, including ones that mark the location of water stations and migrant deaths.
Tomorrow is Election Day here in Canada. The rest of the world might not notice but to us Canadians, the event holds much interest. If the polls are any indication, it looks like there will be a change in government, if only from one minority government to another.
If you live in the United States and feel paranoid enough about catching the flu, Roche has made available a desktop flu tracker (downloadable exe) that displays flu activity levels on a map of the continental U. S. in three broad and undefined classes. There is also the option of seeing the flu spread over the past few weeks. There is a certain sense of inevitability to watching the entire country become engulfed in a flu epidemic. Which, of course, is the intention. Roche, after all, is the making of the recently popular anti-flu drug Tamiflu.
Since the last posting on the Canadian election on December 22th, the campaign has gotten much more interesting. The election is to be held on January 23rd and, of course, the outcome is still unknown. Pollstr.ca takes a crack at predicting the outcome based on various polls and uses a Google Map to display the result. What makes this map interesting is that, if you disagree with the polls, you can submit your own prediction of how the popular vote will be distributed among the parties and see how that affects who gets elected where. Sadly, no word on the methodology used.
The British Library has posted a number of historical documents for viewing online, including Mercator’s Atlas of Europe. The atlas is a compilation of a number of maps produced by Mercator from the 1560s and 1570s. It is presented in a Flash format that allows the user to turn and magnify pages. It is also accompanied by an audio guide.
Ed Parsons points to Spatial-Literacy.org, a site that maps surname distribution in the U. K. The site just become operational yesterday and is experiencing high traffic volumes but it's worth a look, particularly if you have an English, Welsh or Scottish ancestry. It provides a distribution map of a selected surname for 1881 or 1998.
This April will mark the 100th anniversary of the famous San Fransisco earthquake of 1906. The Bancroft Library at Berkeley has an online photo exhibit of the event and the fire that followed, including a stylishly done interactive map. Users can click on an area of the city to display photos of that area.
. . . for Manhattan only, that is. Cory has taken the time not only to map all the Starbucks locations in Manhattan but to calculate the location where one would be closest to all the Starbucks in Manhattan, the Starbucks Center of Gravity. See the map and a brief description of how the center of gravity was calculated.
A map depicting the world as the Chinese knew it in 1418 indicates that perhaps Coulmbus wasn’t the first explorer to set eyes on North and South America. A 1763 copy of a 1418 map is set to go on display in Beijing and at the National Martime Museum in Greenwich, U. K. next week.
Not great cartography but an interesting subject to map. The Pejudice Map shows a map of the world with a number of labels attached to various countries indicating what those countries are known for. Someone has gone through the trouble of searching the Internet using Google to find out what various nationalities are known for. Who knew Kenyans were known for their metaphors, Americans for their dislike of walking or Swedes for their carving of Viking longboats?
Anyone who has used online mapping services for directions probably has encountered the occasional odd set of directions for commonly travelled paths. Perhaps the most direct route wasn’t suggested to get to a destination. The Register has noted a number of such oddities in Microsoft’s MapPoint - the latest being the placement of a hotel in the middle of the English Channel. Other cartographic aberations include driving directions from Norway to the U. K. via the North Sea, and Wales to Ireland via the Celtic Sea. Other curiosities are listed by The Register but the most interesting one is the ad by Microsoft’s Windows Server System that moves Switzerland to Russia.
Digital Acoustic Cartography has attempted to map noise patterns of everyday objects and events - e.g. the closing of a car door. Essentially, the acoustic pattern resulting from an event is turned into a relief model of sound; this is combined with a photographic overlay of the noise maker. The result is a three-dimensional map of the object and its sound. The process is still experimental and, if nothing else, produces interesting images. The website offers a very short explanation of the process.
The European Digital Archive on Soil Maps of the World has taken it upon itself to scan and make available soil maps from around the world. According to the site, “less and less new, fundamental soil data are being produced these days; the older data and information are being pumped around more and more. Therefore it is vital to preserve the older data (in this case maps) as they are building blocks of most current soil information. The user of present-day, derived information should have easy access to the source material, if only to assess the reliability of the derived material. ”
globalhealthfacts.org has a small interactive Java-script map of the world that displays health facts about each country. Move the cursor over a country and a little table displays statistics for that country, including the number of people living with HIV/AIDS, TB and malaria. Clicking on a country provides a more detailed table of information, including demographic and economic data. Data is also available for download in MapInfo TAB format.
Making Maps: A Visual Guide to Map Design for GIS
Spirit of Aloha, Aloha Airlines in-flight magazine, has a cover story on the mapping of the Hawaiian Islands in its January / February issue, available online. Included are a number of small images of various historical maps, generally from the late 1700s on. This history seems to begin with Captain James Cook. “Not only was [Cook] the first European to chart the Hawaiian Islands, between 1778 and 1779, he was also the first to outline the extent of the southern ice mass, the coastline of Australia and New Caledonia, and chart many features on the northwestern coast of North America and various parts of the North Pacific.” An interesting article, though not as interesting as its companion article mentioned earlier in this blog.
Postini, a service that provides email and information management protection, has a couple of dynamic world maps that display sources of email spam and viruses. No legends accompany that maps but a note in the downloadable data file indicates “that intensity should be considered an arbitrary measure of event size; an intensity of zero does not mean that nothing happened.” The maps are not pretty nor is the process by which the data is mapped explained but they do display an interesting phenomenon.
Looking for some property in New York City? PropertyShark has a searchable database of properties that displays maps, images of properties and relevant property information. The database is searchable by address or you can simply click on a map to select a property. As well, a number of different layers can be displayed in the map, including flod zones, proposed developments, and tax value. Finally, any map you make can be easily exported to Word as a png file. According to an Inman.com news story, PropertyShark has photographed all 40,000 buildings in Manhattan. Is the direction web mapping will be heading in the near future?
Tom Patterson of the U. S. National Parks Service, has produced a digital elevation set of the world using SRTM30 Plus and publicly available bathymetry data. The result is a dataset that he’s called CleanTopo2. “In CleanTOPO2, manual editing to the elevation data itself has removed many of the bathymetry artifacts. Until the day arrives that improved bathymetric data are released by the scientific community, CleanTOPO2 offers a stopgap solution for those creating maps and related graphics.” Patterson goes on to explain some of the edits and provides examples of before and after edit images. Data is in tif format, is about 68 MB in size and is available to download for free.
