Talk:GRAPHC

jens 09:31, 22 February 2012 (UTC) It was discussed at SNPWG14 to add an information of, tja hard to decribe, well, if the photgraph was made from sea level or from aircraft.
How should we name that? Elevation of camera with two values: shipborn and aircraft? I have no better idea at the moment.

raphael 20:46, 22 February 2012 (UTC): Viewpoint? Camera viewpoint? (Definition: The location of the camera from which a photograph was taken.)
Allowed values:
"surface" or "surface vesssel" or "sea level": Photograph was taken with a camera near sea level.
"aerial": Photograph was taken from an aircraft or balloon.
"satellite": Satellite imagery.

horizontal
low obligue
high oblique
vertical

jens 13:30, 2 March 2012 (UTC) discussed by phone, I guess it can easily be seen from the photgraph provided wether if was taken from vertical or an oblique position. Do we really have to provide this particular information?
