deserve to be buried it. photogrammetry uses the images to remotely surveying the earth's surface. the digital processing of the photos creates a three dimensional image of the search area. and when you make the three d. map it allows the investigator team to get an overhead view in a plane parallel to the slope of the surface here at very very high resolution when you get that three d. map you can orient that map or however you like. the researchers can digitally scan the site of the former camp for any irregularities. they will need to do that because the physical search has not paid off.
