GIS IN DISASTER MANAGEMENT

Geographic Information Systems (GIS) provide tools and methodologies to collect, analyze, visualize, and disseminate spatial data related to natural hazards, which is important for hazard mapping and natural disaster management.

TECHNOLOGY USED IN DISASTER MANAGEMENT

Early Warning System

In order to build early warning systems for a variety of calamities, technology nowadays is essential. Seismographs are tools we use to measure tremors during earthquakes. While hydrological models and satellites can assist anticipate floods, meteorological data can predict cyclones well in advance.

Role of mapping in disaster management

Proper mapping will be helpful not only for pre-disaster preparedness but also in rescue and relief operations with greater accuracy and speed. With the data/information collection, storage, retrieval becoming highly technological and scientific.Remote sensing and how it is used in disaster management

Remote sensing provides valuable data and insights for various aspects of disaster management, including early warning systems, damage assessment, and resource allocation. It helps in monitoring and predicting natural hazards, assessing the impact of disasters, and facilitating effective response and recovery efforts

Hazardous occurrences brought on by earthly natural processes are known as natural catastrophes. A flood, an earthquake, a storm or cyclone, a volcanic eruption, a tsunami, and other geological processes are examples of natural disasters. Disasters that are man-made or anthropogenic are brought on by human activity. Disasters caused by people have an adverse effect on other living things, humans, and ultimately ecosystems. All forms of pollution, nuclear, chemical, and biological disasters, terrorist acts, and other unintentional calamities are examples of man-made disasters.

Floods: Floods can be anticipated with the use of GIS and remote sensing tools. For an efficient and cost-effective approach to managing catastrophes, the National Disaster Management Authority (NDMA) and State DisasterRemote sensing and how it is used in disaster management

For an efficient and cost-effective approach to managing catastrophes, the National Disaster Management Authority (NDMA) and State DisasterManagement Authority (SDMA) combined remote sensing techniques with GIS/photogrammetric technologies. Identifying flood-stricken areas and providing shelter for afflicted individuals are made possible in large part by GIS technology. Furthermore, the appropriate locations for the construction of retaining wall structures and a detour for stormwater drainage. Additionally, this technique aids in the creation of base maps (Gram Panchayat, District) that display the position and arrangement of boats as well as the rescue team's plans, and various degrees of vulnerability maps that illustrate the places that are regularly affected by floods.

Earthquake One of the earliest foes of humanity is the earthquake, which can today be thoroughly mapped and studied. Planning and overseeingpreparedness programs is made easier for national, regional, and local emergency agencies by the use of GIS. Infrastructure locations and demographic data are analyzed using GIS-based Urban Information Systems.

The precise location of historical sites' spatial data is provided via remote sensing and GIS technologies. The goal of remote sensing and GIS technologies is to lessen the impact of a disaster by visualizing its main vulnerabilities and damages. During the incident, swift responses were possible because to the results of GIS technology.
