aerial orthophotograph (© swisstopo), the Swiss National Map
1:25,000 (© swisstopo) and a classical terrestrial oblique
photograph (© C. Scapozza). The mountain symbol of the Blenio
Valley (Canton Ticino), with its typical pyramidal form, is directly
perceivable only from the terrestrial perspective.

extension. On the left, 3D cartography window with a stereoscopic
visualization of a digital image strip of the Val Torta rock glacier (©
swisstopo, 2008); on the right, the final result mapped in 2D on a
315㼻hillshade of the swissALTI3D DEM (© swisstopo, 2013).
)LJXUH – Horizontal displacements (2009–2013) measured by
dGPS on a drone ortophoto of the Stabbio di Largario rock glacier.

)LJXUH – Realization of the digital image of 6 km wide strips
collected by digital airborne pushbroom imagery by the Airborne
Digital Sensor ADS80 of the Swiss Federal Office of Topography
swisstopo. The acquisition of the three different available scenes
(backward, nadir and forward scene) in accordance with the
camera angle is also shown. From AMBROSI & SCAPOZZA (2015).
)LJXUH – Georeferentiation and orthorectification of a non-metric
oblique photograph with the WSL-Monoplotting-Tool; (Detail of)
the six historical oblique terrestrial photographs analyzed by
SCAPOZZA HW DO. (2014); Comparison between the front position
between 1924 and 2008 photographs and synthesis of the front
positions determined by monoplotting.
