Aerial Photographs based Height Measurement using Parallax

There are several methods through which height/elevation can be measured using satellite image and aerial photographs . In case of satellite image such as, Cartosat, ASTER, Worldview I & II and others are used to create height or elevation data in the form of digital elevation model . Aerial photography, LiDAR mapping are very common for creation of elevation data on higher scale/resolution for detailed study. In the last article, relief displacement used to measure height of any object on earth surface. Here in this another method will be discussed to measure height of any given object on the earth surface. Parallax for Height Measurement using Aerial Photography Parallax Concept Photogrammetry is capable of measuring elevation of earth surface. Aerial photographs/stereo pair satellite images can be used to measure elevation differences through the use of parallax method. New launched satellite are providing stereo pair satellite images images such worldview-2 etc.
