Abstract
This paper reports research that resolves the issue of data integration from multiple heterogeneous datasets for performing network analysis operations. The current geospatial standards, protocols and technologies are investigated and implemented through the research. The methodologies to solve the creation of network topology on-line for supporting network analysis are suggested and tested. A software system is created with a number of tools to support such system. A scenario of application is tested around the real world dataset of the train network in London (UK).
1. Introduction
Utility and infrastructure networks impact society globally and are managed in both the private and public sectors. A huge amount of money has been invested to improve and develop these networks and their supporting systems to help service customers and solve business problems. The use of GIS for utility and infrastructure network is well-known and widespread. It provides a variety of tools to assist in the management and manipulation of utility and infrastructure networks. GIS can also support specialist tools for the analysis of linear networks. The specialised tools to manage and build topology are required to maintain the data and analyse network. The network GIS applications that use such tools include asset management, site selection, risk analysis and shortest path.
