Photogrammetric processing and pixel based classification of ship wreckage in NWT

A request for a high resolution orthophoto came from Henry Carey, a former Parks Canada archaeologist. Henry collected aerial photography with a large sensor DSLR from a helicopter during a field visit in 2013.The helicopter flew transects to collect the imagery A photogrammetric model and basemap were create using Agisoft Photoscan. Archaeological material was identified using nearest neighbour classificaiton (Geomatica Focus). A vector shapefile output could then be used by archaeologist to gather additional site data. A DSM and Contour lines were also generated from the pointcloud, helping to identify microtopographical features.
