    The first photo of Earth from space was taken on October 24, 1946, from an altitude of 65 miles above the surface of New Mexico. It was captured by a 35-millimeter motion picture camera as that camera was propelled skyward on a German V-2 missile. 

    However, most people recall of the iconic Blue Marble - a famous photograph of the Earth, taken on December 7, 1972, by the crew of the Apollo 17 spacecraft, at a distance of about 45,000 kilometres (28,000 mi).

    Since spaceflight began, millions of photos have been taken of Earth from space, many of these images are never seen by a wider audience.

    Challenge Description:

    Create an app, platform or website that consolidates a collection of space imagery and makes it more accessible to more people.

    Functional Specifications:

    Many photos do not have location information or meta information.  Develop a way to geotag the photos as well as assign it a description of the country, area, or region featured.

    Consider ways to make the data more interactive, potentially through the use of social media, gamification, crowd-sourcing, or citizen science applications.

    Develop an API for this platform that allows others to utilize the great data in a more accessible format as well.

    • 234,118 Image Dataset (CSV)


      A zip file with 234,118 image links and metadata. Fields are as follows:

      mission – shuttle or station mission identifier – AS = Apollo, GEM = Gemini, personally, unless these images were really good I’d skip these, NASA and NM are NASA-Mir (Shuttle visiting the Mir space station), SL is Skylab, the rest are Shuttle or ISS.
      roll – camera roll number/name
      frame – frame #
      width – of the image
      height – of the image
      filesize – of the image
      CLDP – cloud cover percentage (I think. Kim?), yep, that’s right
      Lat – latitude (of the thing photographed) latitude of the center point of the image, not the “thing”
      Lon – longitude(of the thing photographed) longitude of the center point of the image, not the “thing”
      geon – geographic name (of the thing photographed)
      feat – any features (of the thing photographed), well features at the center of the image, then working outwards if notable

      The same data that is in the CSV dataset, formatted as a JSON array of objects rather than a CSV file.
