DMSP/OLS夜间灯光数据,主要包括稳定灯光数据、辐射标定夜间灯光强度数据、非辐射标定夜间灯光强度数据三种产品.
DMSP/OLS night light data, mainly including stability data, radiation calibration light night light intensity data, the radiation intensity of light at night calibration data three products.
具有数据获取容易、能够探测低强度灯光、不受光线阴影影响、方便为城市化强度及其时空分异分析提供条件等优点.
Has the data acquisition easily, can detect low intensity lights, from the light shadow influence, convenient for urbanization strength and its spatio-temporal variation analysis provide conditions, etc.
目前,关于DMSP/OLS数据的研究成果已有很多,主要集中于城市发展研究、人类活动及效应研究、生态环境影响研究等方面,但对于成果的系统归纳总结性研究却几乎没有.
At present, about DMSP/OLS data research results have had many, the main focus on urban development research, human activities and effect, ecological environment impact study research and so on, but for the induction summary system research achievements have hardly.
基于此,本文分析比较了现有DMSP/OLS数据研究实例,针对已有成果研究目的、技术方法以及方法优缺点等进行归纳总结,探索DMSP/OLS夜间灯光平均强度数据的应用前景.
Based on this, this paper analyses the existing DMSP/OLS data example, according to the previous research objective, technical methods and the approach to the paper summarizes the advantages and disadvantages, explore DMSP/OLS night light intensity of average data application prospect.
最后,总结了该数据的未来研究趋势：（1）对数据本身处理方法深入研究；
Finally, this paper summarizes the research trend data future: (1) the data itself processing method to research;
（2）数据应用领域应进一步扩展；
(2) data applications should further expand;
（3）DMSP/OLS数据与其它数据模型的集成研究应进一步深化；
(3) DMSP/OLS data and other data model should be further integration of;
（4）将现有研究成果结合,进一步研究.
(4) will the existing research results union, further study.
