Abstract

The main objective of this research is to apply Geographic Information Systems (GIS) for construction and renewal of underground infrastructures. As a first step, a suitability analysis to determine location of existing underground infrastructure is performed. Next, a GIS template is developed using a digital elevation model (DEM) to get a three dimensional visualization of the underground infrastructure. Creating a Google Map using ArcGIS is one of the key features of this research, which provides an exact location of the existing site and distances from the nearby reference points. Once the GIS data is exported to Google Map and Google Earth, it provides a wide variety of information, such as pipe parameters like diameter and length. Another important objective of this research is to develop a graphical user interface (GUI), which is an innovative technique to help in getting a walkthrough beneath the surface. Several case studies are presented that describe GIS applications for the installation and renewal of the existing underground infrastructure. These case studies give a clear picture of the advantages of the GIS over other methods both in terms of cost and time and the least cost path analysis.
