Just How Tall Is It?

It’s a good day for mapmakers: JAXA (Japanese Space Agency) just made all the elevation data from its DAICHI spacecraft available to anyone for free. DAICHI, or the Advanced Land Observing Satellite, was launched in 2006 and operated for five years taking precise land measurements that were used, among other ways, to study disaster sites. (Its successor, DAICHI-2, launched in 2014.) JAXA has started to process a 3D map of the world using the 3 million images taken by DAICHI. The public can access elevation data from East and Southeast Asia now; the rest should be available soon.
