The increasing demand of 3D spatial information is nowadays there for all to see and it is
involving all the branches of the economy, coming out of the traditional civil and
environmental sector. Smart cities implementation, facility management, real time as built “as
designed” verification, modelling of existing building and neighborhoods, are becoming
crucial and challenging activities, to carry out with new survey approaches (Marinelli et al.,
2017; Schmitz et al., 2015, Barsanti et al.; 2012; Lauterbach et al.; 2015; Khashayar et al,
2018; Boavida et al, 2012). Moreover, those process involve various professionals with
different background so unequivocal data and compatibility of procedures must be
guaranteed. Thanks to the continuous and recent technological progress, innovative
instruments are now available in the market, making sustainable fast mapping acquisitions,
also of indoor environments. This paper as first investigates how the latest indoor Mobile
Mapping System (iMMS) Heron, based on SLAM (Simultaneous Localization and Mapping)
algorithms was effectively used to acquire 3D data and high-resolution images especially in
indoor environments. As second, the case study investigates how sensors with different
characteristics and peculiarity have been exploited in order to carry out a multiresolution
survey, being able to satisfy both the need to have detailed models and large amount of data.
