Applications of GIS: Disaster Management and Emergency Response

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Manipulation and Analysis

Manipulation and Analysis

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Levels of Use of a GIS

Levels of Use of a GIS

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Introduction to GIS

Introduction to GIS

Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...

Statistical Analysis System (SAS)

Statistical Analysis System (SAS)

SAS, short for Statistical Analysis System, is a powerful data analysis, management, and visualization tool. Developed by the SAS Institute in the early 1970s, SAS has evolved into a comprehensive software suite used across various industries for statistical analysis, business intelligence, and predictive modeling.
Applications: SAS finds applications in numerous fields, including healthcare for clinical trial analysis, finance for risk assessment, marketing for customer data analysis, and...

Area of Science:

Emergency Management
Human-Computer Interaction
Information Systems

Background:

Emergency response coordination faces significant challenges, particularly in major accidents.
Decision support systems (DSS) integrated into communication systems aim to improve coordination.
Existing DSS in rescue services often suffer from under-use and usability problems.

Purpose of the Study:

To investigate the usability issues of decision support systems (DSS) in Swedish emergency organizations.
To identify factors contributing to the under-use of DSS in rescue services.
To provide recommendations for improving DSS design and implementation.

Main Methods:

Literature review on decision support systems and usability in emergency response.
Analysis of survey data from rescue personnel regarding communication system usability.
Qualitative assessment of decision-maker task structures and contextual factors.

Main Results:

DSS development is often driven by technological capabilities rather than user needs.
Usability problems hinder the effective adoption and use of DSS in emergency response.
Lack of consideration for decision-maker tasks and context is a key issue.

Conclusions:

Future DSS development must prioritize user-centered design, focusing on task structure and context.
Essential functions include providing a visual overview of the event and logging decision-making processes.
Improved usability of DSS is crucial for enhancing coordination and decision-making in major accidents.
