EarthKAM Explorer provides web-based 3D exploration of satellite images taken by middle school students through the ISS EarthKAM program. The initial version was written in a weekend by five developers from Analytical Graphics, Inc. for the NASA International Space Apps Challenge, a global hackathon.
EarthKAM Explorer uses CZML generated by Systems Toolkit to visualize the ISS and its orbit. It uses CZML generated from the EarthKAM data to visualize polygons where images were taken. Cesium camera flights are used to fly to a polygon went it is clicked to reveal the image. EarthKAM Explorer also supports the Leap Motion controller for hand-gesture input.
EarthKAM Explorer took second place in the judging at the Philadelphia event, and received an honorable mention for Best Use of Data in the global judging round.
