The impact of innovative and emerging technologies on the surveying activities

Surveying activities benefit from the continuous and rapid evolution of sensors, methodologies, and processing strategies. Such rapid development influenced the pre-existing geomatics applications in many fields and opened the way to more productive and accurate applications of surveying methodologies. This special issue aims at collecting papers focused on current and/or forthcoming sensors, novel applications and improvements in the surveying practices, and algorithms oriented to the handling of the increasing amount of data produced by automated procedures. Of particular interest is assessing the reliability, performance, precision, and limits for advanced applications in the field of photogrammetry, remote sensing, surveying, and mapping employed in innovative approaches to geomatics. These topics were discussed during the 68th meeting of the Italian Society of Photogrammetry and Survey (SIFET) held in Gaeta, Italy on 20–22 June 2018, and the present special issue includes a number of papers presented during that event.
