Title (up) Analysis of light pollution from floodlighting: Is there a different approach to floodlighting? Type Journal Article
Year 2017 Publication Light and Engineering Abbreviated Journal
Volume 25 Issue 1 Pages 75-82
Keywords LED lighting
Abstract The research which was prepared for this paper was inspired by a real floodlit object. The main distinctive feature is connected with the directionality of its lighting. The „Sezam” building was one of the first to be illuminated in the opposite way to the usual manner of floodlighting. The analysis, based on the measurement of horizontal illuminance on the pavement in front of the building andof theluminance on the facade, leads to some very unusual conclusions. It goes deeper than merely the assessment of the phenomenon of light pollution in the context of floodlighting. Additionally, a short survey about the preferences of lighting directionality in floodlighting and the general concept of light pollution was conducted on a group of over a dozen people. It turned out that people are quite aware of the phenomenon of light pollution and they rather prefer illumination from floodlighting to be from bottom to top.

Title (up) Analysis of Light Pollution in Ticino region during the period 2011-2016 Type Journal Article
Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society
Volume 63 Issue Pages 102456
Keywords Skyglow
Abstract Since 2002, the Environmental Observatory of Southern Switzerland (OASI) has monitored a remarkable set of environmental parameters with the purpose of performing an enhanced observation of the regional environmental conditions. Since 2011, a campaign for the supervision of the artificial nighttime skyglow has been included in the OASI monitoring system exploiting the collaboration with DarkSky association. This network monitors the light pollution in several areas of Ticino, the southernmost Swiss Canton bordering Italy. It consists of multiple stations, which continuously measure the sky brightness. The University of Applied Sciences and Arts of Southern Switzerland, in collaboration with Politecnico di Milano, introduces the results of a study regarding the skyglow evolution during the period 2011-2016. The time-series of the OASI network were pre-processed to detect and discard data affected by natural perturbing events, such as moon and clouds presence and sun effect during twilights. In a second time, a distribution analysis of the data and an evaluation of the brightness trend during the considered period were performed. The results show that light pollution in Ticino is strictly influenced by the northern area of the nearby Italian Lombardy region and that during the surveyed years a decreasing of the pollution occurred.

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 Panamanian DMSP/OLS nightlights corroborates suspicions of inaccurate fiscal data: A natural experiment examining the accuracy of GDP data Type Journal Article
Year 2017 Publication Remote Sensing Applications: Society and Environment Abbreviated Journal Remote Sensing Applications: Society and Environment
Volume 8 Issue Pages 99-104
Keywords Remote Sensing
Abstract Governments have incentives to misreport their economic productivity to advance their political goals. These incentives have long been understood, but the validity of government data has been difficult to estimate in the absence of viable external estimates. Using historic Defense Meteorological Satellite Program's Operational Linescan System nightlights imagery we corroborate reports that Panama's government data has been increasingly politicised since the handover of the Panama Canal on 31 December 1999. The Canal Handover represents a “natural experiment” in which the production of government data changed in Panama for reasons separate from the desire to manipulate that data. The amount of light a country produces at night, known as nightlight production, has been shown to strongly correlate with GDP. Using subnational Panamanian nightlight production from 1996 to 2012, we detect a significant divergence between the relationship of subnational reported GDP and nightlights before the Canal handover (when the U.S.A. was very involved in their statistical agencies) and the correlation after the handover (with no U.S. involvement). Our results indicate that between 2000 and 2012, Panama reported approximately 19% more GDP than what was expected by their nightlight production from 2000 to 2012, or a total of around 40 billion U.S. dollars. Our results suggest governments may engage in political manipulation of government statistics to improve the appearance of government performance. While indirect data can never definitely confirm economic phenomena, this analysis presents a unique research design and application of historic satellite imagery to corroborate reports of GDP misreporting.

Title (up) Analysis of the Dynamic Urban Expansion Based on Multi-Sourced Data from 1998 to 2013: A Case Study of Jiangsu Province Type Journal Article
Year 2018 Publication Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 10 Pages 3467
Keywords Remote Sensing
Abstract Recently, with the fast speed of urban expansion, research concerning the regulation of urban built-up area expansion is a significant topic, especially in Eastern China with its high urbanization level. The Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) nighttime light data has a high association with the urban-rural distribution, which provides a new method to study urban expansion effectively and with relatively high accuracy. Between 1998 and 2013, China experienced a rapid economic development period, making it crucial to learn the patterns and driving forces to better manage urban master planning and sustainable development. The urban built-up area for the research years are mapped, and the annual urban expansion speed, urbanization intensity index, and built-up area gravity center are analyzed in this paper. The results will show that the amount of the urban built-up area grows continuously from 1998 to 2008, with the development focus in southern Jiangsu, while from 2008 to 2013, the development center moves to northern Jiangsu. The main driving forces behind this urban built-up area expansion are population growth and economic development.
