Abstract: The stable lighttime data, the radiance-calibrated nighttime light intensity data and the non radiance- calibrated nighttime light intensity data are the three major products that have emerged in the field of the DMSP/OLS nighttime light data. It has several advantages, namely, easy acquisition of data, detection of low-intensity lights, unaffected by shadows, convenient provision of conditions for urbanization strength and its spatial- temporal difference analysis, and so on. At present, there are many research results on DMSP/OLS data, which mainly focus on city development, human activity and effect, eco-environment impact, but there are few studies on systematic results. This paper analyzed the existing researches on DMSP/OLS data, summarized and drew some conclusions based on the existing research results, the technical methods and the advantages and disadvantages of the methods, as well as explored the application prospect of DMSP/OLS nighttime light average intensity data. It predicted the future research trends of the data: (1) an in-depth study on processing methods of the data; (2) further expansion of data application; (3) the integrated study on DMSP/OLS data and other data models need to be deepened; (4) combine the existing research results, make further research on mechanism issues of geography phenomenon.
