Summer camp, Google Earth style!

July 21st, 2008 · No Comments · Maps

::: via :::

Last week, 18 Googlers brought their 9-12 year old kids to our Mountain View headquarters to spend their week learning with Google Earth and all the other geo tools. By the end of the week, the “Geo Camp” participants had mastered Google Earth, Maps, and Docs, and used these tools to research environmental issues, virtually tour the planet (and universe), and collaborate to build sophisticated presentations on habitats around the world.

I’m not sure who had more fun — the teachers or the kids! As the week came to a close, we asked them all to reflect back on what they had learned, and I just can’t help but share some of their responses:

I didn’t know I could ____ with Google Earth

  • fly (Matt, 6th grader)
  • see all the rides at Disney World (Gwen, 4th grader)
  • learn about endangered animals (Aditya, 7th grader)

The coolest place I saw was….

  • the Space Needle (Jack, 7th grader)
  • the Empire State Building (Jake)
  • the entire universe (Andrew, 6th grader)

When I’m a grownup, I’ll use Google Earth to…

  • find a place to go on vacation (Nick, 5th grader)
  • share global awareness about different countries to other people (Esha, 9th grader)
  • look at other galaxies, and see if there’s traffic (Aditya, 7th grader)

If I worked on the Geo team, I would…

  • build more SketchUp buildings (Erik, 5th grader)
  • create a ship simulator in which you could be the captain of a ship (Ashna)
  • make a driving feature so people could pretend to drive on roads (Warren, 7th grader)

A Shift in Online Map Searching

July 21st, 2008 · No Comments · Maps

::: via :::

“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 Scott 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 Scott 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?

Geotagging on Linux

July 21st, 2008 · No Comments · Maps

::: via :::

Fellow Googler and GPS geek extraordinaire Marc Merlin has created a guide to geotagging photos and GPS tracks using gps visualizer and gpsPhoto. This is a technical, hands-on guide that describes how to create very compelling geo mashups.

Whether or not you follow this guide, it is worth checking out Marc’s presentation. He cleverly uses Google Maps, photos and GPS data to describe details of a multiday trip on Northern California’s Lost Coast Trail (one of my favorite places).

Improvements to Ads in the Maps API

July 21st, 2008 · No Comments · Maps

::: via :::

Posted by Jim Payne and Brandon Badger, Maps API Team

Our Maps API team strives each day to develop features to help developers build the next generation of great maps mashups. One of the requests that we’ve received from our developer community is to build features that will help convert map traffic into revenue for their site. To that end, we’ve been working hard on improving the program that allows Maps API sites to choose to display Local Business Ads on their map as part of the AdSense for Content program. As with all Google ads products, we feel that success depends on providing ads that actually improve the user experience, while at the same time allowing businesses to reach their target audience.

Although we’ve had an ads program in the API for some time, this week, we are pleased to announce some key improvements to that system:

  • An improved user and advertiser experience. Ads now display “flat on the map,” and we’ve introduced new more informative category icons. We’ve also built a system to “nudge” ads so they do not obscure key elements on the map. Check out an example of the new look and feel.
  • Improved coverage. We introduced GAdsManager last year, but didn’t show many ads. Now, our coverage is much improved without impacting relevance. We also now show ads for all countries where the Local Business Ad format is supported. (For your ad to show up on API sites, you need to opt-in to the “Content Network.”)
  • Continuous ad serving. You may have noticed that ads would not be refreshed when users panned the map, so your highly interactive Maps API site wouldn’t be able to take advantage of the program. We’ve changed this. Ads are now loaded whenever the user moves the viewport to a new location.

We hope that these improvements will help you generate some revenue from your Maps API site and continue to make it better.

You can read more details about these changes on the Maps API Developer Forum or sign up for an AdSense account to get started.

NOTE: To be clear, this program has always been and remains completely opt-in for API users. You are under no obligation to display ads in order to use the Maps API. For more details see the Maps API Terms of Service.

the Cannibal Map of the World

July 21st, 2008 · No Comments · Maps

::: via :::

(click on map to enlarge)

In this day and age, cases of cannibalism are quite rare (or medium, or well done – sorry couldn’t resist that one). The barrage of media attention unleashed whenever a case does occur speaks volumes of our fascination with this, one of the darker taboos of humanity. More often than not, these cases are enshrined in popular culture by the movies and books about them that are avariciously devoured by a sensation-hungry public.

Two instances immediately come to mind: the story of Armin Meiwes, the German internet cannibal, who in 2001 sollicited (and, incredibly, found) a victim online, prepared to be prepared into a meal by him; an example of collective cannibalism (and a case more inspired by necessity than depravity) was that of the Uruguayan plane that crashed high in the Andes somewhere in the 1970s, forcing its survivors to tuck into flesh of the deceased.

The word ‘cannibalism’ derives from a Spanish term for the inhabitants of the Caribbean, whom they considered to be man-eating savages (the name of the bad guy in Shakespeare’s The Tempest also derives from the same root: Caliban). Another, less popular term is anthropophagy, Greek for ‘the eating of humans’.

Cannibalism is believed to have been practised by the Neanderthals and, in a more or less ritualistic context, by many ancient (modern) human cultures the world over. The object of the practice seems not to have been hunger so much as power – eating others is the ultimate way of establishing dominance over them, and/or acquiring their strength.

This map, from the German/Austrian publisher A. Hartleben, dating from the early 20th century by the look of it, presents a map of the range of anthropophagy, both contemporary (in red) and historical (in yellow).

Remarkably, Europe is completely cannibal-free. Are there really no historical records of anthropophagy in Europe’s ancient history?

Africa is marked with some historically cannibalistic tribes (Basuto in Southern Africa, Kakongo in the Congo area, Ashanti and the enigmatically named Flups in Western Africa) as well as a few still active ones, mainly in what was then still deepest, darkest Africa: the Niam Niam (this sounds suspiciously onomatopeic), Kissama, Mangbattu and Manyonoa; further south are the Matabele of present-day Zimbabwe.

The whole of Asia is blighted only by the past sins of the Ostiaks, a Siberian tribe and – bet the Dalai Lama never brags about this – the Tibetans.

Indonesia, Micronesia and the rest of Oceania are marked by many contemporary instances of cannibalism, in Australia, New Guinea, Borneo (Dayaks) and Sumatra (Bataks). Maori cannibalism has been besieged in New Zealand and many (but not all) of the archipelagos to its north.

Anthropophagy was shockingly widespread in North America (according to this map at least), with a continuous swathe of territory marked by the practice, ranging from the east coast (Algonquins, Iroquois) through the Midwest (Chippeway, Dakota) to the west coast (Oregon peoples). Other areas were to be found in Texas (Apache), Louisiane (Atacapa) and Florida.

Canniballism also was a well-established practice in Mesoamerica (Aztecs, Mayas) and South America (Caribs, Quechua, Tupi) and still ongoing with some Brazilian tribes, notably the Guarani.

It should be remembered that cannibalism probably was over-reported – people in previous centuries being as fascinated by the taboo as we are – and often used as a propaganda tool: cannibalism being the ultimate yardstick of barbarity, and the ideal excuse to subjugate the peoples accused of it.

Many thanks to Jeremy Schein for providing this map, found here on Wikipedia.

Combining a Globe and an Atlas

July 21st, 2008 · No Comments · Maps

::: via :::

Globe and atlas More good stuff from Modern Mechanix; this time, an item from the April 1930 issue of Popular Science about a combination globe-atlas: it was a globe “with a complete index and gazetteer inside it. Inserted in the globe are two small windows containing magnifying glasses. 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?
