Here is how GIS helps in higher catastrophe administration.

From local weather change to pure disasters, pandemics to man-made disasters, all have impacted thousands and thousands of individuals worldwide. India is ranked because the 14th most weak nation on the planet as a result of excessive weather-related occasions. Out of 36 States and Union Territories (UTs) in India, 27 are disaster-prone.

Across the yr, India witnesses numerous climate occasions akin to extraordinarily heavy rainfall, warmth and chilly waves, snowfall, thunderstorms, mud storms, floods, and so on. Such occasions are a consequence of both pure or man-made elements; each trigger excessive lack of life, property, and infrastructure. In accordance with a report by Nationwide Catastrophe Administration Authority, in India, 12% of the whole land space is susceptible to floods; 68% is weak to droughts, landslides, and avalanches, 58.6percentof landmass is earthquake-prone, and out of seven,516 km shoreline,5,700 km is susceptible to cyclones.

Immediately, India has made great progress in forecasting disasters utilizing Geographic Data System (GIS) expertise. Throughout the 2019 and 2020 cyclones Hud-Hud, Gaja, Amphan, and Nisarga, GIS performed an instrumental position in emergency preparedness by means of planning and evaluation and saved many lives. GIS fosters improved environmental understanding, strategic determination making, monitoring of local weather change impression, and ascertaining future dangers. The expertise has been utilized throughout numerous sectors together with water, agriculture, healthcare, city planning, amongst many others.

Agendra Kumar, President, Esri India Know-how Pvt Ltd which is into mapping and spatial analytics options, says, “In healthcare, GIS supported on the frontline in opposition to the worldwide pandemic coronavirus illness 2019 (COVID-19) battle by means of mapping present instances, planning quarantine centres and hospital infrastructure capacities, figuring out hotspots and weak populations. Now, as the federal government prepares to roll out the distribution of the COVID-19 vaccine, GIS real-time spatial mapping and evaluation capabilities will play a key position within the environment friendly distribution.

Mr Kumar additional says “GIS supplies the flexibility so as to add updates from distant places for incident administration and provides speedy injury evaluation and extra correct restoration operations. As rebuilding begins, GIS aids native, state, and central authorities companies with expertise that helps collaboration between a number of organizations. An enterprise GIS platform that shops and manages all related info supplies a standard working image to all of the stakeholders.”

GIS is an integral a part of the catastrophe administration lifecycle; the preparedness stage of the pre-disaster state of affairs adopted by throughout and post-disaster which is attributed to response and restoration and rehabilitation efforts.GIS supplies correct spatial information and insights to catastrophe response methods and permits visualization of essential vulnerabilities and injury. This functionality of GIS was demonstrated within the Nepal earthquake tragedy in 2015. The expertise was utilized for guiding emergency responders to affected areas and mapping the impression to coordinate the reduction effort.

GIS-based functions inculcated interactive maps displaying the earthquake places, depth, well being services, base camps, and injury evaluation. Additionally, the appliance acted as a standard platform for information assortment round incident reporting for infrastructure injury or fireplace and data dissemination to reduction staff concerned in offering help to these affected by the devastation.

Preparedness is the important thing to the success of any catastrophe administration plan and GIS expertise is among the key enablers. Mainstreaming GIS into all of the phases of catastrophe administration planning presents a chance to higher put together and expedite and amplify the impression of planning and reduction efforts by means of larger effectivity.

Throughout the 1999 Odisha floods, the Odisha State Catastrophe Administration Authority utilized GIS-based satellite-based distant sensing expertise for efficient administration. GIS expertise assisted in numerous phases of the catastrophe administration cycle; ranging from figuring out places to assemble multipurpose flood shelters and weak factors within the embankments to provoke restore. This adopted by strengthening and preparedness efforts and grid evaluation to arrange the Automated Climate Stations (AWS). The method additionally concerned creating district and gram panchayat degree vulnerability maps and base maps indicating the placement and operation of boats and deployment of rescue personnel.

There’s a life cycle to any disaster or catastrophe. Following the response, the section is a chance to construct resilience. Integrating GIS into the catastrophe administration response framework improves the planning course of. It permits customers to know the impression of potential injury and additional anticipate useful resource utilization through the emergency. Entrance-line departments get entry to real-time info to quickly monitor the altering conditions and additional share up-to-date info with the general public and different departments. GIS-based dashboards and stay maps present authoritative information that enables departments to make knowledgeable selections. Response to catastrophe and emergencies contain the next levels:


A profitable prevention plan entails complete planning and evaluation to reduce the results, cut back loss, and a proactive strategy to the plan. GIS expertise supplies the aptitude to map and analyze all forms of hazards to visualise potential impacts. Primarily based on the inputs of impression on infrastructure and inhabitants, vulnerabilities will be recognized to determine priorities.

The Karnataka State Pure Catastrophe Monitoring Centre (KSNDMC)makes use of a GIS dashboard to watch the rainfall throughout the state, on a real-time foundation, from the info shared by rain sensors put in at numerous places.  The stay information captured is used to foretell any potential flooding incidents as a result of heavy rainfall, determine affected places, and push advisories by means of SMS to be probably impacted areas.


Authorities develop motion plans as an efficient response to an emergency. With GIS interactive maps, authorities view essential info in layers and make data-driven knowledgeable selections. GIS helps preparedness by means of a catastrophe administration system that entails visualizing and analyzing dangers, modelling and designing mitigation initiatives, and speaking up-to-date info with different departments to construct resilience in any respect ranges.


GIS supplies highly effective mapping and analytics functionality to answer catastrophic occasions. It supplies superior instruments that keep situational and operational consciousness; rapidly analyze the incident impression; assess the injury; deploy sources; and educate, inform, and warn residents. With GIS instruments, authorities can get entry to emergency unit places, shelter inhabitants capacities, provide inventories, energy, determine places of public security sources, and standing of the general state of affairs.

To map and monitor the unfold of coronavirus illness 2019 (COVID-19) instances, the Bruhat Bengaluru Mahanagara Palike (BBMP) arrange a battle room that integrates GIS expertise. GIS-based maps, apps, and dashboards displayed real-time information about hospital capability, ICU beds, ventilators, and date; zone; hospital; age; and gender-wise particulars day by day. The officers immediately obtained entry to real-time information from well being and police departments for situational evaluation, actionable insights, and to additional impart info to residents.


GIS assists in restoration efforts by restoring the affected space to regular. This consists of making selections that deal with short-term and long-term necessities; akin to medical care, shelter, meals, rebuilding, reemployment, and the restore of important infrastructure. GIS additionally performs an vital position within the evaluation of harm and losses to additional determine priorities for reconstruction and decide actions for numerous subject operations akin to first help and well being, transportation routes.

Constructing resilience by means of higher consciousness and preparedness is the necessity of the hour. Adopting to disaster administration life cycle framework boosts efforts in the direction of prevention for what comes subsequent. At a time when each second counts, understanding and decoding the “the place” issue is essential to prevention, preparedness, response, and restoration.

GIS performs a significant position in addressing threat situations; nonetheless, its widespread adoption in emergency operations must be totally accelerated to make sure the disasters of the longer term are much less catastrophic. With the utilization of GIS expertise fostering threat evaluation, planning, situational consciousness, restoration operations, and enhanced collaboration, catastrophe response will proceed to enhance and in the end present a greater and safer atmosphere for folks.
