  Title (up) Analysis of Lighting Changes in the Tourist City Edogawa Using Nighttime Light Data Type Journal Article
  Year 2018 Publication Journal of the Indian Society of Remote Sensing Abbreviated Journal J Indian Soc Remote Sens  
  Volume 46 Issue 10 Pages 1617-1623  
  Keywords Remote Sensing  
  Abstract When assessing remote sensing data, nighttime light data have shortcomings that can be attributed to sensor limitations and the influence of the natural environment. Signal leakage errors in nighttime light data were identified in this study. A regression model was created to reduce signal leakage error by selecting sampling points in coastal area. Lighting variations in Edogawa between 2008 and 2013 were compared based on the Defense Meteorological Satellite Program’s nighttime light data. The lighting variation characteristics in Edogawa from 1992 to 2012 at 5-year intervals were also analyzed. The results show that the 2002 FIFA World Cup held in Japan led Edogawa’s light digital number values to peak in 2002. The annual Edogawa lighting changes from 2007 to 2013 were also explored. The 2008 global financial crisis led to the lowest compounded night light index and average digital number in Edogawa during these 7 years.

  Title (up) Analysis of Seven Years of Globe at Night Data. Type Journal Article
  Year 2014 Publication Journal of the American Association of Variable Star Observers Abbreviated Journal J. AAVSO  
  Volume 42 Issue 1 Pages 219-228  
  Keywords Skyglow  
  Abstract The Globe at Night (GaN) project website contains seven years of night-sky brightness data contributed by citizen scientists. We perform a statistical analysis of naked-eye limiting magnitudes (NELMs) and find that over the period from 2006 to 2012 global averages of NELMs have remained essentially constant. Observations in which participants reported both NELM and Unihedron Sky Quality Meter (SQM) measurements are compared to a theoretical expression relating night sky surface brightness and NELM: the overall agreement between observed and predicted NELM values based on the reported SQM measurements supports the reliability of GaN data.

  Title (up) Analysis on Luminance of Outdoor Signboards of Commercial Areas in Seoul at Night Considering Light Pollution Type Journal Article
  Year 2015 Publication Journal of The Korean Society of Living Environment System Abbreviated Journal J. Korean Soc. Living Environ. Sys  
  Volume 22 Issue 4 Pages 583-595-589  
  Keywords Lighting; Light pollution; Commercial areas; Night-time lighting; Outdoor Signboards; Luminance; outdoor lighting; artificial light at night; signs; LED signs; LED billboards  
  Abstract As the city is commercialized, the number of stores is increased and it also makes outdoor billboards’ number increased accordingly. And signboards on the street make pedestrians unpleasant, making light pollution by light reflection. In this study, we measured the luminance to target the outdoor signboards of commercial area in Seoul. On the basis of the obtained results, the External system showed high luminance values, and the luminance values of Letter-type system were lower. Furthermore, the measured value at the midnight time was higher, and we considered that the more floating population bring about the high luminance value of the External system. The signboards of External system should be avoided, the Letter-type system should be recommended.

  Title (up) Analyzing parcel-level relationships between Luojia 1-01 nighttime light intensity and artificial surface features across Shanghai, China: A comparison with NPP-VIIRS data Type Journal Article
  Year 2020 Publication International Journal of Applied Earth Observation and Geoinformation Abbreviated Journal International Journal of Applied Earth Observation and Geoinformation  
  Volume 85 Issue Pages 101989  
  Keywords Remote Sensing  
  Abstract Nighttime light (NTL) remote sensing data have been widely used to derive socioeconomic indices at national and regional scales. However, few studies analyzed the factors that may explain NTL variations at a fine scale due to the limited resolution of existing NTL data. As a new generation NTL satellite, Luojia 1-01 provides NTL data with a finer spatial resolution of ∼130 m and can be used to assess the relationship between NTL intensity and artificial surface features on an unprecedented scale. This study represents the first efforts to assess the relationship between Luojia 1-01 NTL intensity and artificial surface features at the parcel level in comparison to the Suomi National Polar-orbiting Partnership-Visible Infrared Imaging Radiometer Suite (NPP-VIIRS) NTL data. Points-of-interest (POIs) and land-use/land-cover (LULC) data were used in random forest (RF) regression models for both Luojia 1-01 and NPP-VIIRS to analyze the feature contribution of artificial surface features to NTL intensity. The results show that luminosity variations in Luojia 1-01 data for different land-use types were more significant than those in NPP-VIIRS data because of the finer spatial resolution and wider measurement range. Seventeen variables extracted from POI and LULC data explained the Luojia 1-01 and NPP-VIIRS NTL intensity, with a good out-of-bag score of 0.62 and 0.76, respectively. Moreover, Luojia 1-01 data had fewer “blooming” phenomena than NPP-VIIRS data, especially for cropland, water body, and rural area. Luojia 1-01 is more suitable for estimating socioeconomic activities and can attain more comprehensive information on human activities, since the feature contribution of POI variables is more sensitive to NTL intensity in the Luojia 1-01 RF regression model than that in the NPP-VIIRS RF regression model.

  Title (up) Application of power line communication technology in street lighting control Type Journal Article
  Year 2018 Publication International Journal of Design & Nature and Ecodynamics Abbreviated Journal Int. J. DNE  
  Volume 13 Issue 2 Pages 176-186  
  Keywords Lighting  
  Abstract Rapidly increasing usage of telecommunication systems causes new transmission technologies and networks to emerge. Not only the efficiency, reliability and accessibility of the network are important, but also the economic issues. One cost-effective solution could be power line communication (PLC) technology, which transmits data using the existing electricity infrastructure. The application of this communication technique is an attractive and innovative solution for the realization of smart cities and smart homes. With intelligent control networks, energy savings can be optimized and the operating as well as maintenance costs can be reduced. Since outdoor lighting systems are the major consumers of electricity, to create a modern, energy-efficient city, intelligent street lighting control is needed. This paper provides an overview of power line communication principles including the theoretical background of data communication, modulation techniques, channel access methods, protocols, disturbances and noises. Furthermore, in order to highlight the benefits of a PLC-based street lighting control system, a pilot project will be presented.
