DESCRIPTION

The 2004-05 lava field evolution was reconstructed using technologies, data and methods spanning from remote to on-situ techniques, from active to passive sensors, from mono- to multi-view photogrammetry, from digital terrain modeling to GIS analysis. In details, this dataset contains:

Single optical and thermal images collected during the eruption and elaborated following the principles of single-image photogrammetry using both Pic2Map QGIS plugin (Produit et al., 2016) and an implemented ad-hoc code to obtain orthorectified images of the lava during its emplacement;
LiDAR data acquired soon after the onset of the eruption and after its end (i.e. on 16 September 2004 and 29 September 2005, Favalli et al., 2009);
A DEM of the lava field when it was active using multi-view photogrammetry methods starting from a set of optical and thermal images collected during the eruption.
