Geocache Causes Bomb Scare in Ottawa

A geocache near a bus rapid transit station in Ottawa triggered a bomb scare that led to a four-hour shutdown of a major boulevard last week, CBC News reported on Monday. Police detonated the package, and are asking geocachers to make sure their packages don’t look suspicious; a local geocacher argues that caches should be clearly labelled and in transparent packaging.

More on Walking Directions

Richard sends along an AP story (on CNN) about online maps for walkers and bikers — it seems that high gas prices are putting people in the mind to think about other forms of transportation, and are noticing that most of our maps and directions are assuming that they will be used by drivers. In addition to mentioning Google Maps’s walking directions, along with a few other initiatives — such as MapQuest’s walking directions sent to cellphones — the article looks at the challenges of shifting from a driver-centric paradigm:

Pedestrians need sidewalks but don’t have to abide by one-way streets. Walkers and bikers can cut through paths or trails not meant for cars, but they must avoid highways. Bikers, unlike walkers, need to think about whether a road is paved and are prohibited from sidewalks in some cities.
All these variables mean the fastest, easiest route for a driver may not be the same as for someone on foot or riding a bike. And developing a comprehensive system for non-drivers requires a tricky step: collecting huge volumes of local metadata and getting them on national databases used by mapping services.

The Mannahatta Project

The Mannahatta Project (thumbnails, egregiously stolen under fair use provisions) The Mannahatta Project’s goal “is to reconstruct the ecology of Manhattan when Henry Hudson first sailed by in 1609 and compare it to what we know of the island today. The Mannahatta Project will help us to understand, down to the level of one city block, where in Manhattan streams once flowed or where American Chestnuts may have grown, where black bears once marked territories, and where the Lenape fished and hunted.” Based on a 1782 map of the island that shows its waterways and topographical features, the Project will create a digital model of the island that will be displayed next year, on the 400th anniversary of Hudson’s arrival, in several formats, including an exhibition, a book, and an interactive website.

Review: Rhumb Lines and Map Wars

Rhumb Lines and Map Wars: A Social History of the Mercator Projection
by Mark Monmonier
University of Chicago Press, 2004. Hardcover, 238 pp. ISBN 0-226-53431-6

Rhumb Lines and Map Wars (cover) Rhumb Lines and Map Wars is Mark Monmonier’s response to the controversy over the Mercator projection stirred up by Arno Peters and his map that purported to be fair to all peoples. Rather than retroactively mixing it up with Peters and his chief critic, Arthur Robinson, Monmonier has taken a step or two back to create a broader understanding of Mercator, his projection and its uses.

Most of us with some knowledge of map projections know that Mercator’s intent was to provide a map usable in sea navigation: angles on the map match constant compass lines. Monmonier reveals that Mercator was a little ahead of his time: it took centuries before the technology (such as chronometers) was developed to make his map one of several essential navigation tools. From the development of sailing charts to the development of Mercator variants such as the transverse and space oblique, Monmonier not only demonstrates the Mercator’s specific uses, but also that the projection was the result of divers hands. Mercator himself rates only a chapter; the map cannot be reduced to the mapmaker.

The source of the controversy over the Mercator projection was its use as a wall map; the Mercator’s dominance began during the 19th century, when ships were king. But by the 20th century its influence was beginning to wane. Other projections began making their appearance in atlases, such as Goode’s homolosine and the Mollweide. National Geographic had been using the compromise Van der Grinten projection on its wall maps since 1922. And, with the advent of aviation and beacon-based navigation, great circles became more important than rhumb lines.

Peters’s attack on the Mercator projection in the 1970s seems a bit odd in this context, which I think is Monmonier’s point. Apart from honking off academic cartographers, Peters proferred a solution that was hardly novel — there are plenty of equal-area equatorial projections out there, which differ only in their secants. But he was able to engage the imaginations of a number of organizations who were receptive to his post-colonial critique.

Monmonier finishes by questioning whether scholars exaggerate the influence of the Mercator projection on social thought: “Did Europe’s rulers and merchants need wall maps or world atlases to justify their actions? Did maps that inflated the size of the British Empire stifle whatever remorse nineteenth-century Britons might have had about racism and economic slavery in Africa or India? More to the point, did anyone ever die because of the Mercator projection?” But critics of the Peters projection don’t get off easy: “Although superior projections abound, the evils of the Peters maps are easily exaggerated. Do its users really think Africa looks that way? Do they never look at a globe, or at other maps? Are map users complete idiots?” (pp. 174-75)

Worth reading for Monmonier’s take on the Peters controversy alone, Rhumb Lines is a fine look at an influential, useful and maligned projection.

Walking Directions

Google has announced walking directions for its online maps: the directions allow you to go the wrong way down one-way streets and appear for distances less than 10 kilometres. Since it’s Google, it’s in beta; there are some interesting hurdles still to be overcome: “[W]e don’t always know if a street has a sidewalk, or if there’s actually a special pedestrian bridge for crossing a busy street. There are still a lot of pedestrian pathways we don’t know about, and they might save you some time if you find them. We’re working on collecting new data on pedestrian pathways and on more effective ways to solicit your feedback, so that we can steadily improve this feature and get you where you need to be as efficiently as possible.”

A Shift in Online Map Searching

“When I stated operating this site in 1997, the most common question I received was related to locating a place on the planet,” writes About.com’s Matt Rosenberg. No more:

Today, site like Google Maps and software like Google Earth have changed the way we find geographic information online. I can’t remember the last time someone emailed me asking for help finding a place. I expect that these people today simply search for the place name themselves. Maybe they start with Google and if the place name was spelled incorrectly, Google provides them with the correct spelling. The search results provide them with a map, images, and an extensive Wikipedia article about the place in question.

I wonder. I’ve gotten a lot of questions asking for maps of a location myself, but it hasn’t occurred to me to pay attention to the kind of trend Matt describes. I still get questions, but they’re more often about a certain kind of map, a map from a certain period, or a specific map being sought. Again, I can’t speak to trends, but I doubt that I have had to field a significant number of queries that could be answered by a Google search since Katrina — and that was a special case.

Are people getting more familiar and comfortable with online mapping?

Inside is a mechanism that reels past this reading glass a fifty-one-foot paper tape bearing place names and descriptions arranged alphabetically.” Why didn’t this catch on?

Its republication, with a graceful introduction by Matt Weiland, is a welcome reminder that the polyglot medley on our maps is, as Mr. Stewart says, ‘a chief glory of our heritage.’” It does sound more opinionated and irreverent than, say, Mark Monmonier’s From Squaw Tit to Whorehouse Meadow (review); checking my copy of Monmonier’s book, it looks like Stewart published two more books about place names in the 1970s.

Inaccurate SBA Map Excludes Eligible Firms

“The Small Business Administration relies on an outdated, inaccurate map to maintain its billion dollar HUBZone program that is rife with fraud, according to a government report,” according to the Washington Post’s small business blog:

The report said the map, which is designed to help firms determine if they’re in a HUBZone area, contains areas that are not eligible for the program and excludes some eligible areas because the SBA has not updated the map since August 2006. The outdated map incorrectly includes 50 metropolitan counties that are ineligible and excludes 27 eligible non-metropolitan areas.
“As a result, ineligible small businesses participated in the program and eligible businesses have not been able to participate,” states the report.

Review: Lost States

Lost States: Real Quests for American Statehood
by Michael J. Trinklein
CreateSpace, 2008. Softcover, 95 pp. ISBN-13 978-1438215334

Book cover: Lost States Lost States: Real Quests for American Statehood chronicles 42 proposals for U.S. statehood that never went anywhere (though some very nearly did). I had no idea there were so many of them. They range from the nutty to the serious, from the Revolution to recently, and from the Atlantic (Iceland?) to the Pacific (the Philippines). They cover the whole gamut: alternative ways of dividing up the territory west of the Thirteen Colonies after the Revolution; partition movements within states (several for Texas and California, but even smaller states like Maine and Alaska — smaller by population, wiseass — have them); new states carved from several adjacent states (a refigured Idaho, statehood for the Navajo nation); more straightforward (and familiar) statehood movements; and annexation proposals.

This self-published little gem is beautifully laid out and engagingly written. Trinklein, a former university professor and PBS documentary maker, brings plenty of funny to the table; his prose is light, entertaining and accessible. While the maps are pretty good (with the boundaries and names superimposed on contemporary maps) the stories behind the proposals are what really make this book: stories of congressmen, adventurers, disgruntled corners of states, and other assorted whackjobs. Really, he should have a blog or something.

As a print-on-demand title, Lost States is a little pricier than regularly published books, I think, but if you’re a fan of the kind of material that appears on Strange Maps, you should grab it. Now.

I received a review copy of this book from the author.

The interface blends the two artists’ work: click the icons on the interactive version of Nolli’s map and see Vasi’s images. From the Web site: “The reciprocity between Vasi’s views and the Nolli map enables one to enter into, and examine Rome in detail, including many neglected corners of the Settecento city. Passing from map to view and from view to map, one can reconstruct 18th century sites that have since changed completely or entirely disappeared.” More from the Eugene, Oregon Register-Guard.

Flounder Lee

“Recently, my artwork has involved mapping in one form or fashion and I thought you might enjoy it,” Flounder Lee writes.

My work titled Self-Organized Mapping was all about mapping my life. I walked and photographed the yard where I grew up (big yard on a farm); it ended up looking like aerial photos which I appreciated. I also “mapped” my internet usage for 3 months, capturing all the images and putting them back down in linear format. Lastly, I showed all of my images from 2000-2005 in grids, each year to a page. I guess this was mapping my journeys, relationships, etc.

Flounder Lee 12

The next series I’ve been working on is about mapping the relationships between governments and indigenous tribes. In the first part of the body of work, I looked up treaties in the Library of Congress and mapped them on their actual locations. I would follow the borders and photograph at preset distances. The work was then put back down over the original map in a grid format (which I guess is becoming my thing at this point).

GPS on the iPhone 3G: Engadget’s Review

I’ll have more to say about location-aware iPhone applications once I’ve installed the 2.0 software update on my iPod touch and played with a couple of them. I won’t be able to say anything about the GPS on the iPhone 3G — with Rogers’s usurious rates in Canada, I won’t be getting one — but Engadget’s review of the iPhone 3G discusses the new phone’s GPS features, especially whether the iPhone can replace a car-based navigation system:

We were able to acquire GPS in as little as a second or two, although depending on your location and reception, you might see that take longer. It’s important to note, though, that the iPhone’s was clearly intended to be a location-aware smartphone — not a dedicated GPS device. There’s a big difference.
That said, there’s an enormous amount of interest by people hoping they can add one more to the pile of devices their iPhone has taken over for. It’s pretty clear why people might want the iPhone 3G to replace their car’s dedicated GPS nav, too. It’s not just a location-aware device with a large, bright screen — it’s also connected (with service you’re already paying for), thus able to get traffic updates, routing information, and so on. The Google Maps app doesn’t provide turn by turn route guidance, though, so while it does provide directions, you can only use it as a stand-in — and not as a full replacement — for a proper GPS device. This problem might be solved later by some intrepid 3rd party developer (like, say, TomTom or Telenav), but there’s been some confusion as to whether this might actually happen, and what Apple’s official stance on GPS nav actually is. And even if this GPS software does eventually come out, the speaker on the iPhone 3G simply won’t be loud enough to be heard over most road noise, so you’d also have to make use of a line-out. In other words, don’t sell your GPS device just yet, okay?

The review also has a couple of tidbits on Google Maps, EXIF data, and application permissions.

Holographic Google Earth

This is interesting: a video demonstrating a touchless, holographic interface using Google Earth.






The projection is 2D, not 3D; think of it as a screen projected in midair, not a fully rotatable virtual globe in three dimensions. Via Google Earth Blog.

The History of Cartography in a Nutshell

The History of Cartography in a Nutshell, an astonishing single-paragraph article by Professor Vladimiro Valerio. From the introductory editor’s note: “About five years ago Professor Valerio was asked to prepare a short article on the history of cartography for a multimedia presentation by the Istituto e Museo di Storia della Scienza of Florence. He was astounded to learn that his article could only be thirteen lines long, but he nonetheless complied. The following is a translation of that article.” Mind you, there are 22 endnotes, with links to map images. Via MapHist.

Thermal London

Thermal image of the English Channel This is interesting: thermal images of London from space, from the air, and from a high vantage point. Part of a site dedicated to thermal imagery of London, but this page is what’s of interest to us. At right, a false-colour thermal image of the English Channel and surrounding land. Thanks to Richard for the link.
