摘要:SPOT 5, the latest in the series of French optical remote sensing satellite, was launched on May 4, 2002 by an Ariane 4 rocket. Its characteristics, in terms of image resolution and swath, and the presence of a new instrument dedicated to Digital Terrain Models (DTM) generation, open a new field of applications, in particular 3D navigation over large geographical areas. The paper describes the new SPOT5 products (images and DTMs), the principles of multi-resolution spectral fusion (panchromatic and multispectral), and the satellite capabilities in terms of images and 3D navigation. It also presents an experimental application, consisting in generating a DTM directly from a panchromatic / multispectral image pair, leading to potential navigation over the whole merged image, without any need for external data
