Abstract |
Artificial night lighting is a unique sign of human activity. Pictures from space show us
beautifully and strikingly how we illuminate our planet. Light emission (and low-light
reflection) data can aid research in numerous fields, from socio-economic studies, via light
pollution, to emergency response. The only instrument currently capable of measuring
nighttime lights from space is the Defense Meteorological Satellite Program – Operational
Linescan System (DMSP-OLS). Although this unique dataset was the first to allow analysis
of our nighttime activities, it has many shortcomings, such as rather coarse spatial resolution
(2.5 km ground sampling distance), only panchromatic visible spectral information and no
visible band calibration, 6-bit quantification, saturation and overglow. By the end of 2011, a
new instrument will be launched, the Visible-Infrared Imager-Radiometer Suite (VIIRS)
onboard the NPOESS1
Preparatory Project (NPP) satellite. This instrument remedies some of
the shortcomings of the DMSP-OLS instrument, but it still is not designed for earth
observation of nighttime lighting and lacks many specifications we advocate here. On June
10th 2011, the High Sensitivity Camera (HSC) onboard the Aquarius/SAC-D satellite was
launched successfully. This instrument has a panchromatic band (450 – 610 nm) and a
resolution of 200-300 meters. The foreseen products and other characteristics are yet
unknown to the authors. |

Abstract |
The angular distribution function of light emitted from cities is unknown, and represents the most important systematic error in skyglow simulations. We describe a method for measuring this distribution using a two camera system mounted on an aerial platform. We present preliminary results from a test flight using such a system, taken over the city of Berlin on July 14, 2011. |

Abstract |
Remote mapping of night lights has been used for decades for mapping urbanization and the global distribution of human activity. Most of this has been accomplished using remote sensing data from the Defense Meteorological Satellite Program (DMSP). The coarse spatial and spectral resolution of DMSP, however, has precluded discrimination of lighting types or spectral characteristics. Recent demonstrations using photography from the International Space Station and airborne multispectral simulations demonstrate significant potential, but high-spectral-resolution field and laboratory measurements indicate that these methods do not take full advantage of the spectral information available. This research demonstrates the use of imaging spectrometer data to identify, characterize, and map urban lighting based on spectral emission lines unique to specific lighting types. ProSpecTIR imaging spectrometer data were analyzed to extract spectral features and these were compared to spectral library measurements on a pixel-by-pixel basis, resulting in a detailed spatial map showing different lighting types. The nature and distribution of lights can be used as a surrogate for measurement of urban development. |

The library provides information about spectral emission lines unique to specific lighting types. ProSpecTIR-VS imaging spectrometer data of Las Vegas, Nevada were analyzed to extract spectral features and these were compared to the spectral library measurements on a pixel-by-pixel basis, resulting in a detailed spatial map showing different lighting types. The nature and distribution of lights can be used as a surrogate for characterization of urban settings, and measurement of urban development. |
