Persistent Hyperspectral Observations of the Urban Lightscape

Abstract

We present the persistent hyperspectral imaging of the New York City urban lightscape, with ~ 7.2 ×10−4 μm spectral resolution, surveyed over 25 consecutive summer nights over a 6 minute time resolution. We train a supervised classifier to automatically determine the location of light sources in each hyperspectral image. This work issues the first urban lightscape combined hyperspectral - multitemporal survey of its kind.
