Black and White Aerial Photos

    


     Black and white aerial photography is data gathered in the visible spectrum rather than in the infrared.  In this part of the electromagnetic spectrum, black and white color values are exactly what we see in the visible spectrum. This aerial imagery allows us to analyze large areas of either developed or undeveloped land in a variety of different spatial resolutions. This black and white aerial example shows the reconstruction of Johnstown, PA in 1891; two years after it was flooded.
