The Japan Aerospace Exploration Agency (JAXA) will begin publishing free of charge an elevation data set that can express undulations of terrain over the world with a resolution of 30 meters horizontally (30-m mesh version). The data set has been compiled with images acquired by the Advanced Land Observing Satellite "DAICHI" (ALOS). As the first step, we will offer the areas in East Asia, including Japan, and South East Asia regions, and will expand the areas to all over the world (within 82 deg. of N/S latitudes). (Please refer to Attachment item 1.)
The data set is published based on the elevation data set (5-meter mesh version) of the "World 3D Topographic Data" (please refer to Attachment item 3), which is the most precise global-scale elevation data at this time, and its elevation precision is also at a world-leading level as a 30-meter mesh version. This data set is expected to be useful for scientific research, education, as well as the private service sector that uses geospatial information. (Please refer to Attachment item 2.)
