法国Spot—1卫星图像已在中国科学院空间科学技术中心等单位的试验研究中应用,并取得初步成果。对五万分之一的Spot卫星图像的分析表明,Spot图像的分辨力比美国陆地卫星MSS图像提高四倍,比TM图像提高10米,接近于两万五千分之一的航空象片。在Spot的全色图像上,相当于100平方米。例如,在北京地区的Spot图像上,不仅许多居民楼清晰可数,还可区 Spot-1 satellite images of France have been used in the pilot studies of the Space Science and Technology Center of the Chinese Academy of Sciences and other units and achieved initial results. An analysis of one-fifth of Spot’s satellite imagery shows that Spot images are four times more resolvable than US terrestrial satellite MSS images and 10 meters more than TM images, approaching one in twenty-five thousandth of an aerial photo. On Spot full-color images, equivalent to 100 square meters. For example, in the Spot image in Beijing, not only many residential buildings are clear, but also the area
