SEMANTIC MODELING OF UTILITY NETWORKS IMPLEMENTATION OF USE CASES FOR DEHRADUN CITY

Vishnu, E.; Saran, S.

The current on-going boom in the field of Building Information Modeling (BIM) and 3D GIS is widely being explored for vast urban related applications, analyses and simulations. Large amount of 3D city models are created using various sources of data. Substantial studies are carried out for above-surface features in 3D city models. This ensures providing relevant information about various spatial analyses over the urban systems and environment. Relevant researches explored the numerous applications of 3D GIS such as disaster management, city administration, urban and environment planning, environmental studies, etc. Utility infrastructures (overhead, subsurface or on-surface) play the critical role in the urban space; still they are not considered in 3D city models. OGC CityGML is acting well behind these applications by integrating the geographic information, semantics and the various interdependencies information with the 3D city model. Moreover, comparative studies over the existing network data models make Utility Network ADE as the perfect approach for data modelling. This research proposes the methodology for 3D semantic modelling of subsurface water supply network along with its various „subsurface, overhead and on-surface‟ utility network components with the help of OGC CityGML Utility Network ADE. This study is conducted for Dehradun area. As a result, semantically modelled utility network data is utilised for successful implementation of use cases such as 1) areas affected by utility failure; 2) street space affected by utility maintenance; and; 3) visualisation. These cases are investigated along with urban space.
