由于地球系统的复杂性和开放性
遥感信息的地学分析具有模糊和多解的特点。遥感信息源的获取能力有了飞跃的进步
而成象机理研究和地学处理过程相对滞后。该文尝试探讨遥感地学分析中所涉及的时间与空间分辨率的临界值与时/空转换问题。并侧重对快速反应、痕迹分析、历史再现与加入信息网络的讨论
从而提出了有关深度开发和充分利用卫星信息资源
集成规模生产流水线的建议。
One of the Focuses of the remote sensing geo-processing
is pointing at the mutual transformations of spatial/temporal information. Namely
to use time series to detect spatial differentiation while to apply spatial trace to identify the temporal changes of phenomenon. Since the earth system is characterized by opening and complexity
these geo-processing always have fuzzy and multi-solutions. The study on the mechanism of remote sensing information mainly utilizes the statistical methods not as robot as the advanced genealogical and dynamic methods. The study on the ground spectrum
especially on the patterns of high spectrum
sees some bright prospect
and much success has been reached when vegional differentiation is employed. The transfer of the remote sensing information between the lithosphere
hydrosphere and biosphere is indeed more profound than the same procedure in the atmosphere to which much research effort has been directed
because the information is somehow attenuated or amplified when it is applied from physical procedure in lab to natural environment. This is the very knowledge that we should obtain more. Current remote sensing application and technology have been bottlenecked by how to fully utilize the information sources of all sorts and to further the knowledge of geo-process
into such applications. For instance
analyses on the remote sensing data from NOAA AVHRR and Japanese ADEOS-1 have not been developed in a pixel-by-pixel manner
while heavily overlapped ground stations in Southeast Asia cause tremendous waste on such information. Global change and regional sustainable development is and will receive increasing concern from the side of the earth system science
especially at the turn of this century. Satellite remote sensing has outstanding contribution to global change studies in the past. Through a full line of analyses such as remote sensing archaeology
deep underground information transfer
image overlapping
cartographic comparison and fractal analysis
remote sensing is capable of reconstructing the historical procedure of both nature and Chinese civilization of 5.000 years. On the basis of more and more such historical evidence being proven
remote sensing shows convincing capability of serving regional sustainable development. As the Internet spread worldwide and China’s information industry rapidly develops
current manipulation on remotesensing information
such as transferring
storing
processing
analyzing and application
is challenged. Around the year 2
000
both airborne and satellite remote sensing image or data will be quali- fled as a multimedia source
completely digitized
flowing on the "infomation super-highway"
to serve the society with rapidly captured and updated information. After analyzing the general rule of spatial/temporal transformation of remote sensing information
this paper gives two pieces of advice on the basic steps to develop China’s remote sensing technology: ① to independently speed the experiment on small satellites group
and develop more satellite and airborne remote sensing information sources. ② to meet the requirement of information society. China should keep pace with the development of digital telecommunication network at home and broad
integrate assembly lines of remote sensing information
increase the efficiency and effect such information
and lead the nation to a modernized era.
