一、引言自1972年美国发射陆地1号卫星以来,发射了许多遥感卫星(美国居多),并完成了大量的遥感实验。今天,遥感技术、宽频通信、高速计算机的建立及研制对以前几乎不可能做到的全球环境调查、资源勘测显示出了新的能力。在这些环境影响下,日本的遥感活动也开始兴起。国家宇宙事业开发团(NASDA)于1978年在鸠山岛开始筹建地球观察中心(EOC),并于1979年开始直接接收陆地卫星数据。
I. INTRODUCTION Since the United States launched Lands 1 satellite in 1972, many remote sensing satellites (mostly in the United States) have been launched and a large number of remote sensing experiments have been completed. Today, the development of remote sensing, broadband communications, high-speed computers and the development of global environmental surveys that were previously impossible to do have shown new capabilities in resource surveys. Under these circumstances, remote sensing activities in Japan are beginning to take off. The National Space Development Corporation (NASDAQ) started construction of Earth Observation Center (EOC) in 1978 in Hatoyama Island and began receiving direct terrestrial satellite data in 1979.
