Visual Presentation of an Electrical Network:
The second layer corresponds to the distribution network coverage. The low voltage system and customer supply points along with latitude and longitudes are overlaid on the satellite images and/or the geographical maps of an area.
GIS can be used to generates and visualize layered data sets. Data in a GIS are referenced to geography; they have real world locations and could overlay one another. This procedure gives an whole new perspective to data analysis which cannot be seen in a table or list format.
