BRIDGING REMOTE SENSING AND GIS–WHAT ARE THE MAIN SUPPORTIVE PILLARS?
object-based image analysis remote sensing image processing GIS paradigm shift
2015/8/19
This paper highlights recent developments that have led to object-based image analysis (OBIA). We summarize major trends in bridging remote sensing, image processing and GIS and we hypothesize that OB...
AN APPROACH FOR INDOOR WAYFINDING REPLICATING MAIN PRINCIPLES OF AN OUTDOOR NAVIGATION SYSTEM FOR CYCLISTS
Indoor wayfinding landmark signpost decision point node network route graph Constrained Delaunay Triangulation
2015/5/21
This work presents an approach to enhance navigation in indoor environments based on a landmark concept. It has already been proved by empirical research that by using landmarks the wayfinding task ca...
