You're struggling to improve your disaster response planning. How can GIS analysis help?

Depending on the type of disaster, you may need information within hours or days. A lot of content is available for free on the Internet (shapefiles, images, etc.) but it may not be sufficiently relevant, available, reliable or recent. If the area is not too large, aerial drone imagery can be a flexible and effective way to assess a situation or monitor its development.

The first thing is to have quality GIS Land Mapping Data as the very foundation of your AOI - Area of Interest. Needing the correct attributes to perform your FME scripting or Esri Model Builder, is crucial for infrastructure planning and whereabouts. Throughout my years I've seen free data being the catalyst of million-dollar mistakes, let alone with a disaster costing actual lives. The world is getting smaller and the minute details of your base layers will determine the success or failure of work.

After a natural disaster, GIS can facilitate rapid damage assessment by overlaying satellite images, aerial photographs and terrain data to identify affected areas and assess the extent of damage. This information is crucial for prioritizing response efforts and allocating resources efficiently

GIS analysis can enhance disaster response planning by providing spatial insights and supporting decision-making processes by : Using GIS to identify and map areas vulnerable to different types of disasters (e.g., floods, earthquakes, wildfires). Conduct risk assessments and Utilize GIS to assess resource availability and distribution. Integrate real-time data from various sources,including weather forecasts, social media, and sensor networks, into GIS . Analyze population displacement patterns during disasters Develop spatial models to simulate disaster scenarios and assess potential outcomes. Use GIS to create situation awareness maps that provide a real-time view of the disaster situation. Plan for post-disaster recovery .

GIS help to manage the Disaster response as Hotspot and location identification, where need to prioritize do and updating the status of progress visualzation.

When talking about the risk, beside the vulnerability and physical exposure that contribute to hazard prone areas, capacity of the area should be assessed as well. Capacity means the capability of the area to be resilient, for flood for example the water management, dam construction, shelter point, and so on. For covid, the number of hospitals or public healths for covid could be a capacity indicator for assessing risks. If the capacity is high, this will reducing the risk in that area.

GIS can assist in real-time data, especially with boosts in drone imagery. You can use GIS to collect previous spatial data on disasters and make a future prediction models or that same data can be used to mark locations of potential hazard spots. Along with risks, GIS can assist in preparation of adaptation and mitigation plans for future disasters as well

Considero que, uno de los principales aportes que puede brindarnos los GIS en la gestión de desastres, se centra en la prevención, ya que un correcto análisis espacial con GIS, como lo es un modelo ponderativo de variables fisicas y socioenomicas permitirá identificar zonas vulnerables, con mayor probabilidad de ocurrencia de un fenómeno natural lo que a su vez ayudará a las respectivas autoridades a priorizar, establecer planes de prevención, obras y/o proyectos que mitiguen o reduzcan el impacto de un desastre.

Risk assessment and mapping: Identify areas susceptible to specific hazards like floods, wildfires, earthquakes, etc., by analyzing factors like elevation, vegetation, historical data, and infrastructure. This helps prioritize mitigation efforts and inform evacuation plans. Evacuation planning and route optimization: Model and map evacuation routes considering factors like population density, road network capacity, and potential bottlenecks. This helps identify the most efficient routes and evacuation centers. Resource allocation: Map critical infrastructure like hospitals, shelters, and emergency supply depots to optimize resource allocation before and during a disaster.

GIS can be used in suitability analysis using multi-criteria decision-making in determining the probability of certain disasters happening at different locations for easy disaster response planning and management

Coming from a Utility Background, the saying about what goes in is what comes out is extremely relevant. Half of the challenge is having good asset data. This data takes time to build but once it is in place GIS can support; time, date, failures, replacement, etc. information that ultimately provides action items dependent on the situation. In this scenario, supporting disaster response planning. GIS can help provide field crews with vital information about the type of fault; the materials needed for repair and pinpoint the locations of the fault. All to support the efficiency of bringing the utility back online. Location, resources, and materials eliminating waste for the repair.

Es importante que el centro de operaciones recopile la información puntual que va mandando el personal de campo y la despliegue para consulta de los equipos que atienden directamente la emergencia, en caso de incendios forestales por ejemplo identificar el avance del fuego en todos los frentes de ataque ayudará a su control temprano y mantener seguros los cuerpos de atención.

Damage assessment could be analysis by using real time database such as satellite imageries or UAV. This assessment could help decision makers in choosing the priority areas which get the most damage.

GIS analysis can assist the real time situation of disaster situation for effective planning, monitoring processes, and further updates needed or required

Real-time Data Integration: Combines data from diverse sources like satellites, drones, sensors, social media, and ground reports for a comprehensive picture. Tracks the event's evolution, providing insights into its path, intensity, and potential impact. Visualization and Mapping: Create dynamic maps displaying the disaster's extent, affected areas, and critical infrastructure damage, and Identify hotspots requiring immediate attention and areas needing evacuation

GIS improves the disaster response, it helps civil protection to take the best strategy to save people, GIS spatial analysis are useful in mapping the most highly impacted zones and we can also use field data GIS apps to provide real time data which will help in tracking disaster evolution and recovery In summary, with GIS use in disaster risk mitigation we will gain time, efforts and coordination to save lives

En México, la forma más conocida para evaluar el riesgo de desastre se concibe como Atlas de Riesgo, que, tanto en su sistema digital como en su versión impresa son compilaciones de mapas (realizados como producto del análisis SIG) en los que han analizado los fenómenos perturbadores, su probabilidad de ocurrencia y su posibilidad de afectación al sistema ambiental o las zonas con población. Incluye además la ubicación de refugios temporales y un calendario de calamidades donde se pueden consultar aquellos fenómenos que inciden sobre el territorio por temporadas, como las lluvias o las bajas temperaturas.

Before, during, and after a disaster, the amount of incoming data to be processed can be overwhelming, and amid this chaos, communication is the priority: status, risks, and action plans. We are used to thinking of all this data as numbers, as statistics, and indeed they are, but GIS goes beyond that, these numbers represent reality on a map and allow accurate analysis to address the priorities mentioned above. GIS becomes the most valuable resource to communicate this type of information through maps that convey complex information in an understandable way where everyone can engage because it represents their own reality in a life-threatening situation.

La capacidad de comunicar el alcance del desastre, las tendencias de movimiento y el progreso de la estrategia de recuperación son críticas para los tomadores de decisiones. Contar con un GIS potente y las herramientas de ploting adecuadas pueden hacer la diferencia entre una visualización confusa, de carga lenta o incompleta vs seguimiento en tiempo real, con los layers necesarios de análisis y la posibilidad de que los tomadores de decisiones potencien su velocidad de respuesta y adaptación contínua de la estrategia de recuperación. La inversión en base de datos, capacidad de procesamiento, indexamiento y modelado específicos para GIS y herramientas potentes para el ploting de múltiples layers y pares de coordenadas harán la diferencia.

Post-disaster, GIS analysis helps assess the impact on infrastructure, environment, and communities. It aids in evaluating response effectiveness, identifying areas for improvement, and informing future disaster management strategies.

GIS analysis supports evaluating disaster outcomes in managing Iran's water resources at the basin scale by assessing response interventions' effectiveness and community resilience. It enables analyzing data on water availability, usage patterns, and infrastructure status pre- and post-disaster. By comparing indicators like water quality, access, and infrastructure functionality, GIS helps measure the impact of response efforts and resilience-building measures. This evaluation informs future planning, investment, and policy decisions to enhance water resource management and disaster preparedness in Iran's basins.

Programs like Hazus can project disaster outcomes from a variety of events. ArcGIS has tools like network analyst and business analyst which can be useful for escape route planing and understanding the overall demographics of a vulnerable population.
