Since 2014, the Japan Aerospace Exploration Agency (JAXA) has proceeded the project to develop the precise global digital 3D map �ALOS World 3D� (AW3D)*1 covering the global land areas through the use of 3 million scene archives acquired by the PRISM panchromatic optical sensor on the Advanced Land Observing Satellite “DAICHI” (ALOS) operated from 2006 to 2011. The developed digital 3D map consists of digital elevation model (DEM) or digital surface model (DSM) that can represent land terrains with approximately 5 meters in spatial resolution and orthorectified PRISM nadir looking images.
