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 pipelines is available. Repair and replacement of pipes can be carried
out in the optimal manner when based on an efficient information system.
Additional advantages are achieved when the pipelines are
captured in digital form, for instance providing:
| Systematic data structuring. |
- Quick access to information.
- Simple comparison of data for
different pipelines and topography
- Flexible access
to data retrieval and analysis.
- Efficient updating.
- Possible linkage to alpha-numeric databases
e.g. consumer
- Information and statistics.

Mapping of transmission lines includes establishment, use and maintenance
of an information system consisting of:
- Location data i.e. geographic location of the utility
transmission.
- Attribute data i.e. technical and administrative
data regarding transmission lines, e.g. component
type, size, age and ownership.
|
The location should be surveyed and registered in relation to ground
control points. It is thus possible to compare and present different
types of transmission line data, base map data and other types of data
such as information on cadastral ownership.
It has been proven that it is cost-effective to build
up a uniform and systematized register of information on
public utility transmission lines.
Over the years Dimension India has built up considerable
expertise in data capture for utility mapping as well as
interpreting and digitizing information on many types of
transmission lines, e.g.:
- Water mains
- Telephone lines
- Sewers and discharge pipes
|
One of the advantages to a utility company, when employing
a Consultant to carry out utility mapping, is that the bulk
of work in connection with data capture can be carried out
within a short period of time without staff increases or
extra investments in equipment, thus easing the introduction
of digital techniques.
