Visualizing of the below-ground water network infrastructure

Abstract. This research addresses the design and utilization of vertical reference features in Augmented Reality (AR) to aid providing perspective from underground pipes ground surface. The study utilizes 3D GIS data assigns Z coordinates Underground Utility Networks (UUNs) using AHN4 digital elevation Netherlands (and either use standard depth or surveyed depth). However, registering related at vertex level presents registration issues that Esri's current Network Model (UNM) cannot accommodate. A supplementary model is required address this, which can be achieved through features. These multifunctional emphasize height difference between pipe surface used AR applications provide better clues. Additionally, polygons signatures flow direction are utilized enhance visualization.
