Petrochemical / Refinery Resolution Samples

The imagery below are examples of vertical aerial photography imagery taken at five different altitudes which are centered on the identical ground position. The left side images are the full image to illustrate the area of coverage at each of the different altitudes. The right side imagery is to visually illustrate the maximum resolution and scale available at the corresponding altitude.
