GIS IN DISASTER AND EMERGENCY MANAGEMENT

Geographical Information Systems (GIS) have become a vital tool for Emergency and Disaster Management that offers powerful visualisation, analysis and data modelling ability, allowing for essential problem solving and decision-makingNational Geographic Society n.d.

PUTTING THE WORLD AT YOUR FINGERTIPS

What makes GIS so important is its ability to interact with and influence all aspects of disaster management including its mitigation, preparation, response and recovery phases. This has transformed the way society responses to these events. GIS achieves effective management through its ability to take complex data sets and transforms them into understandable and usable information Hartfield 2020 For disaster management GIS offers the capability to understand the relationship that exists between a location, people, features and resources. In other words, this capability to conduct spatial analysis between data points means GIS can assist in locating, identifying, and understanding connections between potential areas of vulnerability and potential hazard exposure Holser 2016.

EVERYTHING HAPPENS SOMEWHERE

Although GIS is essentially just another method for interrupting data, what sets it apart from other forms of data management is that not all data can be easily understood without a a physical or visual context. Location often plays a role that affects what occurs, so a dependence forms between the spatial and non-spatial data. This is intelligence and understanding trought location.Wieczorek & Delmerico 2009

EXPLORE THE WORLD OF CROWDSOURCING

CROWDSORCING IS NOT A NEW CONCEPT BUT CONTINUAL INTEGRATION OF COMPUTERS IN DAILY LIFE HAS RESULTED IN THE PROLIFERATION OF GEOSPATIAL DATA GENERATION AND ITS EMBEDMENT IN SOCIETY

CROWDSOURCING CHALLENGES

The technological advancement and the use of social media has facilitated the speed, quantity and quality of first hand information attained from the ground from community members. From the Haiti earthquake in 2010 to the COVID-19 world pandemic of 2020 it has shown the world how collective efforts materialised in the form map based EMD to assist assessing the severity of the event and damages caused. This can then be used to improve situational awareness, decrease response and recovery time. However it does not come without problems of reliability, volume and cosistancy. As such a framework must be in place to ensure that this method adds value within the GIS application by providing consistent, analysable data and that neither too little or to much information is collected. Often data requires futher sorting to be utalized but this issues maybe resolved as the progression of artifical intelligence and data mining evolves. Spatial Sciences Institute 2019

INTEROPERABILITY IN GIS

Interoperability is the ability to exchange and use of information. It is key to successfully ensuring accesability of information to decision makes no matter the number and diversity of stakeholders involvement

CHALLENGES OF INTEROPERABILITY

A lack of interoperability can lead to slow data exchange, poor accessibility, and misinterpretation. As data is diverse and can come in varing formats such as an engineers CAD file, a GIS workers shapefile or an administrative exel sheet. This can create a considerable resource burden to extract the data or see and understand all the pieces of an emergiency or disasters puzzle but “[t]he emergency management community can move towards one or several closely related standard data formats that can be used in data transfer and information sharing”.
