STAY AWAY FROM HIGHLY REFLECTIVE SURFACES.
An area that is too bright reduces the detail needed to reconstruct the scene. Wet pavement and the roofs of large buildings are often too reflective to capture properly. Mapping should be done at a different time of day when sunlight is not reflected into the camera.
CHECK THE EXPOSURE.
White roofs of buildings and dark wooded areas can become overexposed or underexposed. They can appear as swirly areas on maps since not enough data is available in those areas. Scouting the survey area ahead of time, taking pictures, and examining test images help determine the best exposure values.
