World Map with Latitude and Longitude lines (WGS84 Degrees, Minutes, Seconds version) The Geographic Grid. It is impossible to lay a flat sheet of paper over a sphere without creasing, folding, or cutting it—as you know if you have tried to gift-wrap a ball. This simple fact has caused mapmakers problems for centuries. Because the Earth's surface is curved, we cannot divide it into a rectangular grid anymore than we could smoothly wrap a globe in a sheet of graph paper.

Instead, we divide the Earth into what is known as the geographic grid. This is made up of a system of imaginary circles, called parallels and meridians, which are shown in Figure 1.4. Imagine cutting the globe just as you might slice an onion to make onion rings (Figure 1.4 A). Lay the globe on its side, so that the axis joining the North and South Poles runs parallel to your imaginary chopping board and begin to slice. Each cut creates a circular outline that passes around the surface of the globe. Meridians and parallels define geographic directions. We label parallels and meridians by their latitude and longitude. Tomnod. What is Tomnod? What am I looking at? You are looking at a picture of earth, taken from space. DigitalGlobe satellites photograph our planet and collect billions of pixels every day. Tomnod is a place where we try to figure out what is happening in these images by asking YOU, and thousands more people in the Tomnod team, to mark what you see.

How do I mark something in the image? If you see something interesting, mark it by first selecting the appropriate button at the bottom of the screen. How are my marks saved? Every mark you make is automatically, immediately saved to Tomnod. How do my marks help? As we get more and more marks from everyone in the Tomnod team, agreement emerages at the most interesting locations. What happens if I mark the wrong spot? Don't worry if you make a mistake. How do I see a new area? The minimap in the bottom right shows the map you're currently viewing. How do I zoom in/out? The images you see are already at maximum zoom, for the most detailed exploration. Tout sur Google Earth. Plans, cartes, photos aériennes.
