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.

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. 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. 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. 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 at night

DMSP / OLS nighttime light data, including stable light data, the radiation intensity of light at night calibration data, calibration of non-radiation intensity of nighttime lights data three products. With data acquisition easy and can detect low-intensity lighting, shadow effects from light, convenient for the city and its spatial and temporal variation of intensity analysis conditions and so on. Currently, on the DMSP / OLS data have been a lot of research, mainly in urban development research, and the effects of human activities, environmental impact studies, etc., but the results are summarized research system has almost no. Based on this, this paper analyzes and compares the existing DMSP / OLS data research examples, the results have been studied for the purpose of technical methods and summarized the pros and cons, etc., to explore DMSP / OLS nighttime light intensity data, the average prospect. Finally, summarizes the data for future research trends: (1) for treatment of in-depth study of the data itself; (2) data applications should be further extended; (3) DMSP / OLS data with other data models should further deepen the integration of research; (4) combination of existing research results, and further research.

DMSP / OLS night light data, including steady light, night light intensity data calibration data, non radiative calibration night light intensity data of three kinds of products. With the data is easy to obtain, can detect low intensity light, from the light shade effect, convenient for the city of intensity and its spatial difference analysis provides conditions etc.. At present, about DMSP / OLS data the results of research have been many, mainly focused on the city development research, human activities and the effects of, the influence on ecological environment and other aspects, but for the outcome of the system summarized study hardly. Based on this, this paper analyzes the existing DMSP / OLS data a case study, the results of research purposes, technical methods and the advantages and disadvantages of the methods were summarized, the exploration of DMSP / OLS night light intensity data application prospect. Finally, summarizes the data for future research trends: ( 1) to the data processing method research; ( 2) data applications should be further extended; ( 3) DMSP / OLS data and other data model integrated research should further deepen; ( 4) the existing research results, further study.
