PERFORMANCE ANALYSIS OF THE IOPES SEAMLESS INDOOR-OUTDOOR POSITIONING APPROACH [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
Tracking the members of civil protection or emergency teams is still an open issue. Although outdoors tracking is routinely performed using well-seasoned techniques such as GNSS, this same problem must be still solved for indoors situations.
