GIS Based Mapping of Electrical Network:

You have learnt in which the Geographic Information System is a system of mapping of the complete electrical network. The question we address now is: How is the mapping done? What are the systemic requirements? For this we first required to understand what type of data is required to map in a GIS.

All GIS data are made of two elements:

  • Geometric data and
  • Attributes data.

Geometric data refers to the geometry of geographical features like as building features, locality boundary, plot boundary, street boundary, and etc. Geometric data could be one or both of the subsequent:

1          Geo-referenced satellite imagery,

2          Maps generated by surveys.

The geometric data is commonly acquired using a variety of technologies along with one of the following two accuracies:

 

Positional Accuracy

Geometric Tolerance

 

 

 

Coarse Mapping

10 m (using hand held

DGPS or IKONOS)

1-2 m (using

Rodometer and Tape)

Fine Mapping

2m (using Geodesic GPS

and ETS)

Sub-decimeter (using

ETS)

Because of an inherent nature of the technologies deployed,

a.)  "Fine Mapping" is much more capital intensive than "Coarse Mapping".

b.)  "Fine Mapping" is more labour intensive than "Coarse Mapping".

c.)  "Fine Mapping" is commonly two to three times as expensive as "Coarse Mapping".
