Google Maps Mashups


I posted about one of these last week, with the video of the race car (allegedly) driver in Paris and the google map of the city pacing his progress. Now here's a whole blog devoted to various Google maps mashups. I've only viewed a few of them, but they've got ones that show the worldwide locations of ebay real estate auctions, local temperatures anywhere on earth at any magnification level, world coffee finders, ones that show the location of every McDonalds on earth, and many, many more. There are even small towns around the world with twisting, confusing layouts that are using the Google maps satellite photos to map themselves for locals and visitors, with hospitals and police stations and other key elements marked in a Google maps mashup.

One I had some fun with was the Dig a Very Deep Hole application. It's pretty simple; you just pick a spot on earth, click go, and it shows you where a hole would emerge if it went straight down to the center of the earth and kept going back to the surface. Like a toothpick through an olive. Got your shovel in the Bay Area? Pack a swimsuit. You come out in the Indian ocean, somewhat east of Madagascar. Aside from satisfying some idle curiosity, the function vividly demonstrates how screwy a view of the globe is provided by the universally-used Mercatur projection maps. With the south so squished, and the Pacific Ocean basically disregarded, you've got no ability to judge how far apart things actually are. The Mercatur is entirely an artifact of the earth's unevenly-distributed continents, and it would be interesting to see what kind of flat map would be used if the earth's inhabited land masses were spread all around the globe. Unfortunately, with the pace of continental drift we'll have to wait sixty or eighty million years to find out. More likely we'll be mapping the land on some other planet long before then, and using some pocket-sized holographic projector to view it anyway, so it's kind of a moot point.

Christ, it's a good thing I gave up on digging a hole to China when I got about halfway (it was about 3 feet deep, I was 6 or 7, seemed about right at the time). Looks like that would only work if you happen to live in Argentina or Chile.

This just goes to illustrate that giving up is the only way to save yourself from the pain of failure.
