Mapping and GIS

Most if not all Utilities hold information about their networks electronically.

These systems provide the ability to display a utility's networks in relation to a background map. This allows utilities to hold accurately surveyed information to pinpoint the exact location of their services although data accuracy is still a contentious issue with many utilities. Data in systems such as Geographical Information Systems (GIS) is held as features or objects and each feature can be held as a separate map layer allowing users to customise the display. GIS is essentially a large database holding both spatial attributes such as "X" and "Y" coordinates or grid reference and textual attributes such as size, material or year laid.

The spatial attributes allow the other data to be displayed against a map background.

There are many GIS on the market today offering utilities a wide choice of functionality.

Most systems require additional application development over and above the "off the shelf" package to allow specialist spatial analysis of the data.
