Photomensuration

Aerial photographs taken by box cameras from hot air ballons… from the early aircraft of the wright brothers vintage…world War I and II aerial photography … and the dawn of the digital era in the early nineties, each was a landmark in the evolution of Photogrammetry to the finely honed science it is today.

From the very basic use for aerial reconnaissance to the mathematically complex procedures of orthorectification and DEM generation, Photogrammetry has seen it all. It is still an interesting coffee table argument within the academia and among photogrammetrists about the future of aerial photography and photogrammetry, due to the availability of LiDAR and high resolution satellite imagery. Today with availability of very high resolution aerial digital cameras, digital photogrammetry is here to stay. This has also opened up venues for applying image processing techniques which were earlier the main stay of data from remote sensing satellites.  Editor

TOP STORIES

Study to monitor bears and hunters by GPS

West Virginia University and the Maryland Department of Natural Resources in US are using GPS to study black bears. The collaborative research project will monitor the movement of Maryland's black bears by using global positioning radio collars and determining hunter movements through the use of GPS armband units.

Researchers to create Tsunami Hazard Maps for East Coast

Two University of Rhode Island researchers have been awarded an $86,000 grant from FM Global, property insurers, to create maps of the East Coast of the U.S. that will identify potential flooding and damage that could occur if a tsunami struck the region.

ARTICLES OF THE WEEK
What You See Is What You Get

Dr James R. Williamson
123 Photogrammetry
Texas, USA

When I first started working with photogrammetry the standard commercial method of collecting the photography was with large format cameras of one kind/type/brand or another. The view was almost always straight down from an aircraft (platform) flying in regular patterns/flight-lines and at a constant altitude. Since that time not much has changed, except the platform, camera, method of collection, processing, analysis procedures and time from start to finish.




Reconstructing the Great Buddha of Bamiyan

A Gruen
Professor and Head
Institute of Geodesy and Photogrammetry
Switzerland

Co- Authors:
Fabio Remondino
Li Zhang

Statues of Bamiyan were cut from the sandstone cliffs and they were covered with a mixture of mud and straw to model the expression of the face, the hands, the arms and the folds of the robe. Two such colossal statues were demolished on March 2001. After the destruction, the Afghanistan Institute & Museum, Bubendorf (Switzerland) and the New7Wonders Society & Foundation, Zurich (Switzerland), launched a campaign to reconstruct the Great Buddha at original shape, size and place.
