论自动化和智能化空间对地观测数据处理系统的建立

未来１０年遥感对地观测技术的发展使得遥感影像的获取将走向多种传感器、多分辨率、多谱段和多时相。各国计划发射的对地观测卫星将使我们能够同时获取大量的、不同分辨率的、多谱段的可见光、红外、微波辐射和侧视雷达的数据。从而构成用于全球变化研究、环境监测、资源调查、灾害防治的多层次遥感影像金字塔。为了能够及时地、充分地利用这些对地观测数据来回答地学研究和人类社会发展所面临时的问题，更好地发挥遥感为国民经济建设服务的巨大潜力，必须从技术上建立一个自动化和智能化的空间对地观测数据处理系统。鉴于目前应用滞后于发射，软件落后于硬件的现实情况，本文简要叙述建立自动化和智能化空间对地观测数据处理系统的必要性和可能性，分析建立该系统的主要目标和需解决的关键技术并希望国家集中各有关方面的人力和财力来共同攻关，以建立和完善我国的地球科学信息系统，提高综合研究与深入分析的现代化水平。

On Development of an Automatic and Intelligent Remote Sensing Data Processing System for Earth Obser-vation from Space

The progress and development of remote sensing technique for earthobservation in the next 10 years makes data acquisition possible to be multi-sensor,multi-resolution, multi-spectral and multi-temporal.A number of earth observationsatellite programms will provide us with huge remote sensing data with different re-solution,different spectra throughout visible, infrared,themal infrared and microwave. These data build up a pyramid of image data for the investigation of globalchange,environment rnonitoring, resource surveying and disaster prevention. It is ne-cessary to develop an automatic and intelligent remote sensing data processing systemfor earth observation from space in order to use these data quickly and successfully inreal time or on time to answer the facing problems of geo-science research and hu-man social development and to exert the potentials of remote sensing in national eco-nomy development.Facing the real situation that the satellite application does notcatch up with the satellite launch and the software development does not catch upwith the hardware updating, this paper briefly describes the necessity and possibilityfor developing an automatic and intelligent remote sensing data processing system.The main goal of this system and the key technique points to be solved are also an-alyzed in the paper.We hope our government will pay more attention and put en-ough manpower and financial support frorn related departments into this project inorder to set up and improve Chinese Geo-Science information system to a higher levelin syntheic research and effective analysis of the earth and its environment.
