North Korea Mapping Oddities
A look at the paucity of GIS data and geographic information about North Korea, including on Google Maps.
Animation of Southern Lights (Aurora Australis)
NASA’s IMAGE satellite captured an amazing light show of the southern lights (aurora australis) back in 2005. The event was recorded on September 11, 2005, four days after a solar flare sent an ionized gas of protons and electrons known as plasma towards the earth. The solar storm generated a ring of light observed in the animation. [...]
Updated 3D Global Topo Data from NASA
Based on measurements from NASA’s Terra spacecraft, a new 3D topographic map has been released as a joint effort by NASA and Japan. The digital elevation model (DEM) was developed from imagery obtained from the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument aboard Terra. ASTER is one of five Earth-observing instruments launched Dec. 18, [...]
Global Datasets from NASA’s Earth Observatory
Global datasets covering observations about the ocean, land, atmosphere, energy, and life are available for exploring and downloading as KMZ or GeoTiff files. The data is processed from MODIS (or Moderate Resolution Imaging Spectroradiometer) which is on the Terra (EOS AM)and Aqua (EOS PM) satellites. The two satellites combined view the entire surface of the earth every one to [...]
