“…Cho et al (1999) and Kiyofuji et al (2001) determined that the bright areas in the OLS images, created by 2-level slicing, were caused by light produced by the fishing vessels. Rodhouse et al (2001) reported the frequency of light occurrences in cloud-free imagery, and associated these lights with fishing vessels.…”

This study used Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) satellite images to classify and analyze the spatial and temporal variability of nighttime fishing vessel lights in the Sea of Japan. OLS images can detect the powerful lights used to attract squid. We examined DMSP/OLS nighttime visible images from 1994 to 1999. Fishing areas of the Japanese common squid Todarodes pacificus were defined as the bright areas created by 2-level slicing methods on DMSP/OLS images. T. pacificus fishing areas were mainly found along the east coast of Korea, between Cheju and Tsushima Islands, around the Yamato Rise, along the coast of Honshu, and in northern areas of the Sea of Japan. Using image classification and separability analysis, we divided the Sea of Japan into 7 areas based on different temporal variability in squid fishing area characteristics. The classification takes the potential northern and southern squid migration patterns into account. One of the potential northern migration patterns formed along Honshu Island to the north; another appeared along the east coast of Korea, northward through Yamato Rise. Southern migration patterns were almost the reverse of northern migration patterns. These 7 classified areas also correspond to the oceanographic characteristics of the Sea of Japan, i.e. a polar front at latitude 40°N, the inflow of the Tsushima Warm Current (TWC), and warm eddies. The use of remotelysensed data demonstrated in this study offers a powerful and innovative way in which to determine the migration and ecology of the Japanese common squid.

“…Linescan System (OLS) sensor can effectively detects light emissions from squid vessels (Elvidge et al, 1999;Cho et al, 1999;Kiyofuji et al, 2001;Kim, 2002). Previous studies on the temporal analysis of fishing conditions for common squid were mostly based on long-term oceanic conditions and catch data and those on the spatial distributions of the fishing grounds for common squid focused on monthly variabilities of the fishing grounds (Kiyofuji et al, 2001;Kim, 2002;Cho et al, 2004;Choi et al, 2008 …”

In this study, we estimate the interannual spatial and temporal distributions of fishing grounds at night in the East Sea based on satellite and in-situ data. We observe that the 15℃ thermal front moves in the north-south direction according to the movement of the warm water (above 18℃) in the Tsushima Warm Current (TWC) area, forcing the cold water area (below 10℃) to either expand or shrink. The interannual variations of sea surface temperature (SST) in winter represented by the indicator SST of 6℃ are consistent with the east-west zonal areas in the central East Sea which represented over 1℃ standard deviation of SST in February during 1990-2000. Annual SST in the fishing grounds of common squid fishing vessels, observed both by fishing vessels and satellites range from 9-22℃, with the satellite-observed data having a larger range than the fishing vessel-based ones. The interannual distributions of the common squid fishing grounds in the East Sea are mostly concentrated in the TWC area in the southwestern part of the East Sea and in the coast of southern Honshu and Hokkaido in Japan. The interannual distributions of the nighttime fishing vessels are consistent with the catches investigated from the fishing vessel.

“…Several different datasets, ranging from daily raw data to time-series "stable light" data, have been developed and applied to various observation areas. Popular applications of the DMSP/OLS nighttime images include monitoring human settlement [4,5]; estimating urban population [6] and population density [7], socio-economic activity [8], energy and electricity consumption [9], and gas emissions [10]; measuring impacts of urban growth on the environment [11]; detecting nocturnal fishing vessels [12]; mapping nighttime sky brightness [13] and forest fires [14]; assessing effects of emissions on ecosystem and human health [15,16]; and evaluating damage from natural disasters [17] and military action during wars [18].…”

Since the release of the digital archives of Defense Meteorological Satellite Program Operational Line Scanner (DMSP/OLS) nighttime light data in 1992, a variety of datasets based on this database have been produced and applied to monitor and analyze human activities and natural phenomena. However, differences among these datasets and how they have been applied may potentially confuse researchers working with these data. In this paper, we review the ways in which data from DMSP/OLS nighttime light images have been applied over the past two decades, focusing on differences in data processing, research trends, and the methods used among the different application areas. Five main datasets extracted from this database have led to many studies in various research areas over the last 20 years, and each dataset has its own strengths and limitations. The number of publications based on this database and the diversity of authors and institutions involved have shown promising growth. In addition, researchers have accumulated vast experience OPEN ACCESS Remote Sens. 2014, 6 6845 retrieving data on the spatial and temporal dynamics of settlement, demographics, and socioeconomic parameters, which are "hotspot" applications in this field. Researchers continue to develop novel ways to extract more information from the DMSP/OLS database and apply the data to interdisciplinary research topics. We believe that DMSP/OLS nighttime light data will play an important role in monitoring and analyzing human activities and natural phenomena from space in the future, particularly over the long term. A transparent platform that encourages data sharing, communication, and discussion of extraction methods and synthesis activities will benefit researchers as well as public and political stakeholders.
