  Title Using night light emissions for the prediction of local wealth Type Journal Article
  Year 2016 Publication Journal of Peace Research Abbreviated Journal J Peace Res  
  Volume Issue Pages 0022343316630359  
  Keywords Economics; remote sensing; night lights; spatial prediction  
  Abstract Nighttime illumination can serve as a proxy for economic variables in particular in developing countries, where data are often not available or of poor quality. Existing research has demonstrated this for coarse levels of analytical resolution, such as countries, administrative units or large grid cells. In this article, we conduct the first fine-grained analysis of night lights and wealth in developing countries. The use of large-scale, geo-referenced data from the Demographic and Health Surveys allows us to cover 39 less developed, mostly non-democratic countries with a total sample of more than 34,000 observations at the level of villages or neighborhoods. We show that light emissions are highly accurate predictors of economic wealth estimates even with simple statistical models, both when predicting new locations in a known country and when generating predictions for previously unobserved countries.

  Title Enhanced oil spill detection sensors in low-light environments Type Conference Article
  Year 2016 Publication Proc. SPIE 9827, Ocean Sensing and Monitoring VIII, 98270B (May 17, 2016) Abbreviated Journal Proc. SPIE 9827  
  Volume Issue Pages  
  Keywords Instrumentation; Sensors; Cameras; Long wavelength infrared; Short wave infrared radiation; Spectroscopy; Calibration; Remote sensing; Water; Near infrared; Night vision  
  Abstract Although advances have been made in oil spill remote detection, many electro-optic sensors do not provide real-time images, do not work well under degraded visual environments, nor provide a measure of extreme oil thickness in marine environments. A joint program now exists between BSEE and NVESD that addresses these capability gaps in remote sensing of oil spills. Laboratory experiments, calibration techniques, and field tests were performed at Fort Belvoir, Virginia; Santa Barbara, California; and the Ohmsett Test Facility in Leonardo, New Jersey. Weathered crude oils were studied spectroscopically and characterized with LWIR, and low-light-level visible/NIR, and SWIR cameras. We designed and fabricated an oil emulsion thickness calibration cell for spectroscopic analysis and ground truth, field measurements. Digital night vision cameras provided real-time, wide-dynamic-range imagery, and were able to detect and recognize oil from full sun to partial moon light. The LWIR camera provided quantitative oil analysis (identification) for >1 mm thick crude oils both day and night. Two filtered, co-registered, SWIR cameras were used to determine whether oil thickness could be measured in real time. Spectroscopic results revealed that oil emulsions vary with location and weathered state and some oils (e.g., ANS and Santa Barbara seeps) do not show the spectral rich features from archived Deep Water Horizon hyperspectral data. Multi-sensor imagery collected during the 2015 USCG Airborne Oil Spill Remote Sensing and Reporting Exercise and the design of a compact, multiband imager are discussed.

  Title Changes in outdoor lighting in Germany from 2012-2016 Type Journal Article
  Year 2017 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 19 Issue 2 Pages 112-123  
  Keywords Remote Sensing  
  Abstract Changes in the total lit area and the radiance of stably lit area in the German federal states from 2012-2016 were investigated using the Day-Night Band of the Visible Infrared Imaging Radiometer Suite. Most states increased in both lit area and radiance. The lit area of Bayern and Schleswig-Holstein grew rapidly, at annual rates of 9.7% and 8.8% respectively. Thüringen was dramatically different from the other states, with a 4.5% annual decrease in lit area, and a 17% annual decrease in the radiance of stably lit areas. In at least some cases, the increases in lighting in Bayern area associated with transitions to LEDs, which may not be indicative of a transition towards sustainable lighting. In addition to these results, this paper discusses the role of remotely sensed nighttime data within the context of sustainable lighting.

  Title Reducing the environmental footprint of church lighting: matching façade shape and lowering luminance with the EcoSky LED Type Journal Article
  Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 20 Issue 1 Pages 1-10  
  Keywords Energy; Lighting; Remote Sensing  
  Abstract The lighting of the Church of the Three Kings in Logatec, Slovenia was replaced in 2014. The power of the installation was reduced 96% from 1.6 kW to 58 W, and spill light from the site was effectively eliminated. As a result, the church is no longer visible in nighttime satellite images of the area, indicating a reduction of waste light from the site of at least a factor of 30. This article discusses the concept of sustainability with regards to cultural heritage lighting, within the context of this example.

  Title Measuring the Impact of Insurance on Urban Recovery with L ight : The 2011 New Zealand Earthquake Type Journal Article
  Year 2018 Publication WORKING PAPERS IN ECONOMICS AND FINANCE Abbreviated Journal  
  Volume 2/2018 Issue Pages  
  Keywords Remote Sensing  
  Abstract We measure the longer-term effect of a major earthquake on the local economy, using night-time light intensity measured from space, and investigate whether insurance claim payments for damaged residential property affected the local recovery process. We focus on the destructive Christchurch earthquake of 2011 as our case study. In this event more than 95% of residential housing units were covered by insurance, but insurance payments were staggered over 5 years, enabling us to identify their local impact. We find that night-time luminosity can capture the process of recovery and describe the recovery’s determinants. We also find that insurance payments contributed significantly to the process of economic recovery after the earthquake, but delayed payments were less affective and cash settlement of claims were more affective in contributing to local recovery than insurance-managed rebuilding.
