GIS

GIS can play a significant role in addressing the data gaps in the current energy auditing processes followed by DISCOMs. GIS locates the coordinates of the feeders, transformers and consumers and helps in mapping the entire distribution system. Such a system would help DISCOMs track and manage their assets. Visualising this information will also enable accurate ‘tagging’ of consumers to their respective feeders and transformers — known as consumer indexing.

The variable nature of wind speed and direction affects the critical zones of chemical incidents (spills and effluents). We describe a method to develop a GIS-based “plume rose” using its corresponding wind rose to map the areas that might be affected by a chemical release incident. The plume rose can thus be used in the preparation and response phases of emergency management for an industrial chemical incident. In this study, we examine an industrial region in Bangalore, India and show that seasonal variation in winds significantly change the nature (size and direction) of the plume rose.
