What is the smallest object I can see on a DOQ?
That depends on a number of factors, including the viewer and monitor you are using, as well as the quality of the original photograph from which the DOQ was made. So perhaps it is best to discuss the photographs themselves. They are 1-meter resolution images, meaning the smallest item that can be distinguished is about 3 feet across. That does not mean, however, that everything 3 feet long or more can be identified in the photo. For example, it is usually easy enough to identify a driveway in one of these pictures. If a car is parked in the driveway, you can easily tell what it is. But if a car is parked in the middle of a field, where you wouldn’t expect to find it, you might not be able to identify it as an automobile. The ability to identify features increases with experience in examining the images.
