前言1972年地球资源卫星(1975年改称陆地卫星——译注)发射以来,世界各国对应用卫星资料作为调查和监测地球资源的手段给予很高的评价。许多行业开展着实用化技术的开发。本文拟就林业的应用,结合实例予以叙述。1.陆地卫星资料的处理·分析系统和图象分析装置陆地卫星资料或遥感资料是地球上的地物(资源)辐射和反射光的状态(电磁波能量特性)的记录。这种对电磁波谱(分光辐射)、空间、时相的所谓三个特征空间进行的分析,就是遥感分析系统。
Foreword Since the launch of the Earth Resources Satellite in 1972 (termed Landsat in 1975), countries in the world have given high marks for using satellite data as a means of investigating and monitoring Earth’s resources. Many industries carry out the development of practical technology. This article intends to forestry application, combined with examples to be described. 1. Processing and analysis of terrestrial satellite data Systems and image analysis equipment Terrestrial satellite data or remote sensing data is a record of the state (electromagnetic energy characteristics) of the earth’s surface (resource) radiation and reflected light. This analysis of the so-called three eigenspaces of the electromagnetic spectrum (spectroscopic radiation), space, and time phases is a remote sensing analysis system.
