What is Photogrammetry?

• Believe it or not, but your camera is a remote sensing instrument!
• It is possible to create an azimuthal/elevation angle grid on the photograph.
• This technique is called cloud photogrammetry 
• The azimuth/elevation angle grid is created by knowing the locations of landmarks in the picture and the position of the photographer very accurately-->>
• Hence, it is important to have the horizon in your image with distinguishable features on the horizon.
• The azimuth/elevation angle grid on the image is very similar to putting lat/lons on a satellite image.
• If you have gridded pictures from more than two photo sites, it is possible to triangulate cloud locations to determine their exact locations.
• It is also possible to combine radar data with photogrammetrically analyzed photographs.  Here are some examples.
