INTRODUCTION
● Unprecedented growth in the industrial sector in India (Planning commission, Government of India, 11th five year plan)
● Planning expectations
○ Support sustainable development○ Facilitate continuous planning based on changing
conditions ● Urban industrial disaster
○ Affects large residential neighborhoods○ e.g. Bhopal gas tragedy, 2009 Jaipur fire
INTRODUCTION (contd.)
● Geographical Information Systems has proved useful in○ Planning○ Situational awareness○ Real-time monitoring
● Salient features of tool○ Include mathematical modeling with GIS simulations○ For policy makers, decision makers & urban
planners
● Other tools: CAMEO, RITE
● Developed using open-source technologies
● Web based, interactive
● Model multiple types of disasters (fires,
earthquake, floods etc.)
● Visualize disaster impact
● Routing
● User access control

GIS Analysis Total residential area
● period1 38.946 Sq. Km● period2 145.761 Sq. Km
Residential Area affected by wind velocity (v1) is 8.95 Sq. Km v1 = wind velocity in period2 with change indirectionperiod2 = period1 + X years Based on the population density of a ward, we can also estimate the population that will be affected in case of any emergency

FUTURE WORK
● Modeling emissions from multiple sources ● Temporal analyses ● Using surface elevation model in GIS
computations ● Adding temperature and water vapour
factors to plume model
