Systemic Requirements:
A robust GIS solution for a distribution utility comprises the subsequent:
- GIS application and database software should be OGC (Open Geospatial Consortium) Compliant,
- Differential GPS survey of entities and consumers and overlaying on satellite imagery should be on the subsequent scales:
1 Urban/Cities/Metros on 1:1000 scales.
2 Semi urban on 1:2500 scale
3 Rural area on 1:5000 scale (the survey in rural areas might be restricted to the corridor of HT/LT lines survey rather than covering whole rural area).
- The map resolution should be as follows:
1 Spatial resolution less than or equal to 2.5 metre ground sample distance (GSD) per pixel for urban areas.
2 Spatial resolution less than or equal to 10 metre GSD per pixel for rural areas.
- Door-to-door survey of customers and collection of data should be carried out.
- Utility HQ/Circle HQ as Data Centre should be equipped along with servers and networked with Utility HQ, Divisions, Subdivisions, etc.
- GIS System Testing and Commissioning should be completed for given concurrent users.
The utility must be ready for integrated IT enabling and the essential basic IT hardware and software involving networking must be in place.
