"Looking at the world through via Google Earth offers striking images of the diversity of our planet and the impact that humans have had on it. Today's entry is a puzzle. We're challenging you to figure out where in the world each of the images below is taken. (You'll find answers and links at the bottom of the entry.) North is not always up in these pictures, and, apart from a bit of contrast, they are unaltered images provided by Google and its mapping partners. So I invite you to open up Google Earth (or Google Maps), have a look at the images below, and dive in. Good luck!"

Make a Map is a website that lets you create your own maps of the US and areas thereof using various demographics data. It's still in beta stage but it's got all of the US (at least everywhere I've thought to look) and so far has datasets for median household income, population change 2000-9, population density, median home value, unemployment rate, average household size and median age. It's fun to use and taught me a great deal about my home city. The sitemaker, ESRI, also has a pretty good free globe map software, ArcGIS Explorer, for which you download map layers and add-ins.

Plan your trip to a far away spot on the globe. You might wish to walk in a straight line or maybe just take the shortest route (other than, perhaps, digging). Take your camera in case you pass one of these. [more inside]

That hole in the backyard would not have gone to China. In fact, most of MeFi's readers would have ended up causing quite a leak. With so many 2d projections out there, who can blame us? There is always this introduction to map projections. You can then make your own projection or your own globe. At least it's not as hard as a 2d spacetime map of the universe (with relativity!).

World Sunlight Map. A neat little map showing the encroaching blob of darkness as parts of the world slip in and out of nighttime.
