Major investments need to be made in society’s utility supply lines; water mains, sewage systems, telephone lines, power lines, gas mains, etc. Often the geographic location is recorded on inferior quality maps and in some cases it is not documented at all. Certainty of supply, environmental protection and efficiency of operations, however, require good basic data. Excavation damage can be largely avoided when reliable information regarding location and description of underground utility lines are available. Repair and replacement of utility lines can be carried out in the optimal manner when based on an efficient gisutility mapping system.
