Google Chrome recently introduced Land Lines, a delightful new way to explore the gorgeous satellite images from Google Earth. Landlines invites users to discover new satellite images in two ways: Draw and Drag. With the Draw feature, visitors simply create a small doodle on their monitor or personal device. Next, Landlines, with the aid of machine learning, presents visitors with a satellite picture that contains this line or shape in some form: perhaps as a gridded street, the shape of a mountain range, or the curve of a lake. A caption in the bottom left hand side of the browser alerts readers as to what they are looking at and allows visitors to explore each area in more detail via Google Maps. With Drag, users can "create an infinite line of connective rivers, highways, and coastlines." Both modes of exploration offer innovative and highly enjoyable ways to see the world from one's own computer.

"ut the truth is that satellites are so last century-so much, in fact, that scientists have begun using them to document historical changes. The above picture, from NASA's 38-year-old Landsat program, shows the Lake Djoudj region of Senegal during a drought in 1979 and during a flood 20 years later. Even at this small scale it's clear how much information the pictures contain about how the land has changed."

Students will look at maps and satellite images to see how various settled parts of the Earth have changed over the past few decades. They will then draw maps of their hometown, showing how it might have looked in satellite images in the 1970s and today. This will probably require some research into their town's recent history.

"Compare NOAA satellite imagery from before and after Hurricane Sandy and investigate damage caused by the superstorm in the Mid-Atlantic and Northeast. Click and drag the white bar to compare historical and current imagery. You can also use the included bookmarks to explore some of the the most damaged areas. "

Earthquakes, tsunamis, floods, wildfires... "IcEarth offers an innovative approach for the use of satellite and airborne remotely sensed data and current and historical aerial photography combined with an in-depth explanation of what the data represents. Images, technical application, and topical themes support environmental science, earth science, and geographic inquiry by complementing educators existing curriculum."

"The MODIS Rapid Response System generates daily near-real-time imagery of the oil in the Gulf of Mexico, including GIS compatible formats. Images are available in photo-like, true and false color from both the Terra and Aqua satellites at 2km, 1km, 500m, and 250m resolutions."

Beautiful satellite images from around the world

High-resolution earth imagery has provided ecologists and conservationists with a dynamic new tool that is enabling everything from more accurate counting of wildlife populations to rapid detection of deforestation, illegal mining, and other changes in the landscape.
