Photogrammetry and Multispectral Imaging for Conservation Documentation – Tools for Heritage Specialists

3-D digital outcrop model for analysis of brittle deformation and lithological mapping (Lorette cave, Belgium)

“…Nevertheless, such mineral identification and assemblages' discrimination could be greatly enhanced using multi-or even hyper-spectral sensors that could range from the visible up to infrared spectral bands (e.g., Campbell and Wynne, 2011;Van der Meer et al, 2012 and references therein). Such sensors are already widely used in routine for aerial terrestrial and extra-terrestrial remote sensing but combining large spectral acquisition imaging with digital SfM photogrammetry directly in the field is still in its relatively early stages of development and applicability in geosciences (Minařík and Langhammer, 2016) covering more archaeological purposes at the moment (Jaillet et al, 2017;Pamart et al, 2017;Uueni et al, 2017). For hydrological purposes too, this could have great implications for the detection and the monitoring of moist zones at the outcrop-but also karstic network-scale following lithologies, opening the door to a better understanding of aquifer recharge and groundwater storage regarding the response/control of the lithostratigraphic pile.…”

The Combination of 3D and Multispectral Imaging for Scientific Visualization – Tool for Conservation and Heritage Specialists

“…the specific attributes of two-and three-dimensional art. The results of previous study demonstrated that complex artefact surveys can be successfully and costeffectively committed [1,2,3,4,5].…”
