Abstract
This paper aims to introduce a dynamic 3D environment allowing to elaborate space and time together, a mobile application detecting movement, an evaluation of space-time human behaviors by using 2D and 3D geovisualization methods. For this reason, a case study carried out to observe the mobility in a university campus. The methodology of the study was structured upon (i) spatio-temporal data collection with mobile devices, (ii) dynamic 2D visualization (animation) on temporal GIS environment, and (iii) 2D and 3D geovisualization by using space-time paths and space-time cube. Based on the outcomes of the case study, 2D and 3D geovisualization were compared and pros and cons were discussed.
