NASA's Visible Earth is "a consistently updated, central point of access to the superset of NASA's Earth science-related images, animations, and data visualizations. These images are considered to be public domain and, as such, are freely available to the interested public-at-large, the media, scientists, and educators for re-use and/or re-publication." The results include images from the Terra & Aqua earth observation satellites, and more, at last count totaling 32,120 images, over 45 gigabytes in volume.

        Google Earth is a free virtual globe, map & satellite photo viewing program (there is a pro version you must pay for) which is similar to but different from NASA's no longer updated World Wind. NASA World Wind had a vastly superior user interface compared to Google Earth. If you think of NASA World Wind as like riding a nice, light road bicycle, then Google Earth is like sitting in a little red wagon and pushing yourself along with a stick. Google Earth does have a useful "go to" feature, which when used is as if someone came along and gave you push in your wagon to the city you want to see--but you have to push with the stick to find what you want when you get there.
    However, Google Earth allows the viewing of closeup images of many world cities which are not available on NASA World Wind, and also displays current TeleAtlas maps of the US and Europe which are not available on World Wind.

No longer updated (except in a Java-Android SDK version for developers writing other applications), World Wind from NASA's Ames Research Center is a freeware (totally free) 3-D virtual globe for your PC, using Landsat satellite imagery, Shuttle Radar Topography Mission data, and USGS maps & aerial ortho photos (like Topozone & Terraserver). You can zoom the image in to any place on Earth from satellite altitude. You can also view the Earth's moon, Mars, Jupiter, and other planets. World Wind 1.4 is a 16 MB freeware download.

    To increase your enjoyment of World Wind, you can download the Landsat images and other data as large packages (e.g., Landsat 7 Level 0 is 359 megabytes), so that the data does not have to download (and you don't need to be online) while you are viewing.

    There are also over 200 free add-ons for World Wind, which let you do things like view world maps, good maps and aerial photos of all of France, or maps of South Africa.

  Sources of free US aerial photos (orthophoto imagery)

    "A conventional perspective aerial photograph contains image distortions caused by the tilting of the camera and terrain relief (topography). It does not have a uniform scale. You cannot measure distances on an aerial photograph like you can on a map. An aerial photo is not a map. The effects of tilt and relief are removed from the aerial photograph by a mathematical process called rectification. An orthophoto is a uniform-scale image. Since an orthophoto has a uniform scale, it is possible to measure directly on it like other maps. An orthophoto may serve as a base map onto which other map information may be overlain." --USGS

US National Map gives access to high resolution orthoimagery, mostly with .03 meter resolution.

TIME Magazine, May 23, 1949, p. 63:

THE PRESS: Geography for Everyman
    When Gilbert Hovey Grosvenor took over the National Geographic in 1899, he likes to recall, the circulation was so small (900) that "I could carry the entire issue on my back." Today, says Grosvenor, who share his magazine's passionate addiction to detail, "A single issue would form a pile more than eight miles high, or 79 piles each as tall as the Washington Monument." In its familiar yellow-bordered, arorn-decorated wrapper, this month's issue reached 2,150,000 living rooms, libraries, throne rooms and dentist's offices from Maine to Monaco.

    This week, in recognition of his responsibility for this fine growth, and in tribute to his 50 years of service, the National Geographic Society will present President and Editor Grosvenor with a special medal at a jubilee celebration in Washington's Constitution Hall.

    What Bell Wrought. At 73, Editor Grosvenor is a frail-looking, energetic man with a neat white mustache, a Phi Beta Kappa key and the manner of a Boston Brahmin. Grosvenor was born (with a twin brother now dead) in Constantinople, where his father was a professor at Robert College. Fittingly enough, from his nursery window the future geographer could see two continents.

    Soon after graduating from Amherst College, Gilbert fell in love with Elsie May Bell, daughter of Telephone Inventor Alexander Graham Bell, who was president of the National Geographic Society. When Bell offered Grosvenor a job on the Geographic, he took it (just to be near "Ellie," whom he soon married) and has been there ever since.

    The turn-of-the-century Geographic was a stodgy scientific journal, written with old-fashioned protentousness, and floundering in debt. Grosvenor stuck to the pattern for six years. One day in 1905, a packet of photographs from Tibet landed on his desk. Grosvenor was fascinated by the rugged Tibetan scenery and the Dalai Lama's palace. On an impulse, he spread the pictures across eleven pages. The issue created a sensation: almost by accident, Grosvenor had discovered how to make geography popular.

    What the Lama Brought. In subsequent issues, Editor Grosvenor has stretched his romantic, unscientific definition of geography to cover everything under (and above) the sun. To the Geographic, geography means kites and cats, ostriches and insanity, the Bagdad market and the Berlin airlift, eruptions of volcanoes, bathyspheres and the stratosphere, fishing, fine arts and the sex life of savages. Peripatetic, insatiably curious Gilbert Grosvenor has written 300 articles and taken 200 of the photographs. He was the first U.S. editor to use natural color photographs (a 24-page spread on China and Korea in 1910).

    He has built the National Geographic Society to a reserve fund of $10 million, mostly from the Geographic's tax-free earnings (it is classed as an educational institution). Besides the magazine, the society also publishes books, bulletins and maps, maintains a 20,000-volume library...

    ...Most articles and "legends" (captions) are written by the studious, well-paid editorial staff of 149. Grosvenor sets the tone, which is frequently florid, sometimes quaint, always polite. Says Grosvenor: "We prefer to print only what is of a kindly nature..."
