点击翻译按钮获取中文摘要

SiPSE is an abbreviation of the Satellite image Presentation System for Education. The system is able to provide a data set for 3D representation of the LANDSAT image for any part of Japan via the Internet. By means of a SiPSE viewer, which is also provided via the Internet, one can drive a 3D image in real time movement as a flight simulator. The data set, called the SiPSE data, is based on the digital elevation model data covering Japan with 50 m resolution, and the LANDSAT TM data with the pixel size 28.5 m. The latter data are reduced from the original one by discarding some bands, and by reducing the brightness from 8 bits into 4 bits. TM1-3 corresponding to visible BGR, and TM4 corresponding to NIR are maintained.The above on-line system is described in Japanese for the domestic use.The SiPSE group is also developing off-line systems with larger file size and other functions for research and international use.
