Abstract

Described herein is a method of evaluating artificial lighting of a surface. The method may comprise measuring a first lumen output at a first location on the surface at a first altitude. The method may further comprise photographing the surface from a second altitude to obtain an aerial photograph of the surface comprising a plurality of pixels, each pixel of the plurality of pixels having a second lumen output, and performing an altitude adjustment on the second lumen output to obtain a third lumen output. The method may comprise dividing the aerial photograph into a plurality of zones, each zone corresponding to a section of the surface. The method may further comprise establishing a user-defined threshold lumen output for each zone of the plurality of zones, and identifying a percentage of the total number of pixels in each zone which meets or exceeds the user-defined threshold lumen output.
