This picture from the Terrace Mountain Fire near Kelowna, British Columbia shows the how oblique aerial photos can help determine the extent of and amount of damage from a forest fire. An oblique photo is taken at an angle towards the ground instead of vertically. They are good for rapid estimations and are easy to interpret. They can’t be used for photographic measurements.
Here is the original caption of the photo:
