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
