A FRAMEWORK FOR GEOREFERENCING BASED AUTOMATED RETRIEVAL OF CONTEXTUAL PROJECT INFORMATION ON CONSTRUCTION SITES

This paper presents research that is evaluating the capability of a georeferencing based automated framework in identifying and retrieving contextual project informa-tion on indoor and outdoor construction sites for supporting decision-making tasks of site personnel. For this purpose, a methodology based on a dynamic user-viewpoint tracking scheme using sensors is proposed. Instead of requiring browsing through de-tailed drawings and other paper based media, contextual information can be automati-cally retrieved based on the users ’ location allowing them to directly interact with it in digital format through an Augmented Reality (AR) environment. AR is the super-imposition of computer-generated images over a user’s view of the real world. The addition of information spatially located relative to the user can assist in the perform-ance of several scientific and engineering tasks. The objectives of this paper are to describe the overall framework being designed as well as to highlight the integration of its various hardware and software components
