This paper puts forward a methodology for the generation of high resolution luminance maps from simultaneous hyperspectral VNIR and photogrammetric imagery. The integration of hyperspectral radiance at ground level, properly weighted by the photopic-based coefficients, plus a sensor fusion strategy, provides for the first time a quantitative description of the luminous flux at high spatial resolution and with multi-angle geometry. Accordingly, this methodology allows following up any strategic policy aimed to improve urban illumination management and quantifying its effects in terms of energetic efficiency
