Abstract

Field workers of utility companies are regularly engaged in outdoor tasks such as network planning and inspection of underground infrastructure. Redlining is the term used for manually annotating either printed paper maps or a 2D geographic information system on a notebook computer taken to the field. Either of these approaches requires finding the physical location to be annotated on the physical or digital map. In this paper, we describe a mobile Augmented Reality (AR) system capable of supporting virtual redlining. The AR visualization delivered by the system is constructed from data directly extracted from a GIS used in day-to-day production by utility companies. We also report on encouraging trials and interviews performed with professional field workers from the utility sector.
