Definition:
An orthophoto is an aerial photograph that has been processed (via a scanning and rectification process) in such a way as to eliminate image displacement due to camera tilt and terrain relief, so that it represents every object as if viewed directly from above, as in a map which is usually in an orthographic projection. An orthophoto combines the visual properties of a photograph with the geometric qualities of a map and offers a realistic visualization of the landscape.
For a beach erosion study, high resolution orthophotos were taken at very low tide from just east of McDonald Avenue in Kitsilano to Wreck Beach on the west side of UBC. Beach contours are also available.
Tide Level: Photos were taken when the tide was at - 2.67 m. (lowest normal tide is – 3.0 m)
