General trends of space remote sensmg technology are overviewed from the non-renewable earth resources stand point. Since the launch of Landsat-1 by NASA, in both Japan and US the applicabilities of space technology for the assessment of global resources have been extensively investigated, hence in this paper general movements of Landsat project, including future Landsat-D, are explained as well as other related US projects such as the ones which utilize future shuttle flights. In addition, some brief concepts on European space activities, especially on French satellite "SPOT" are studied. Furthermore, the importance of understanding the general international situations which Japan has to take into account bor its own projects is emphasized and discussed.
