Applications of GIS: Disaster Management and Emergency Response01:29

Applications of GIS: Disaster Management and Emergency Response

325
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 Analysis01:21

Manipulation and Analysis

205
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 GIS01:29

Levels of Use of a GIS

233
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...

Burn Injuries01:22

Burn Injuries

3.7K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Design Example: Alignment of a Road Line Using GIS

227
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

177
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Area of Science:

  • Global Health
  • Geospatial Health
  • Surgical Care Access

Background:

  • Timely access to specialist care is crucial for time-critical conditions like burn injuries.
  • Significant global inequalities exist in temporal access to healthcare services, particularly between high-income and low-resource settings.
  • Geospatial modeling and census data highlight these discrepancies in burn care access.

Purpose of the Study:

  • To quantify global disparities in travel time to specialist burn care.
  • To evaluate the potential of eHealth strategies to mitigate these inequalities.
  • To assess the impact of telemedicine on expanding burn care coverage in rural Ghana.

Main Methods:

  • Utilized geospatial modeling with data from the Malaria Atlas Project and census data.
  • Compared population access to 1-hour travel time for specialist burn care in the UK and Ghana.
  • Modeled the impact of extending eHealth services to 8 district hospitals in Ghana.

Main Results:

  • In the UK, 95.6% of the population can access specialist burn care within 1 hour, compared to only 29.9% in Ghana.
  • A 3-fold population difference in access was observed between the two countries.
  • Extending eHealth to 8 rural Ghanaian hospitals could increase 1-hour access coverage from 29.9% to 45.3% (5.1 million people).

Conclusions:

  • Significant inequalities in access to specialist burn care persist globally.
  • eHealth strategies, including telemedicine, offer a feasible approach to improve local care quality and capacity building in low-resource settings.
  • Decentralized care models leveraging eHealth can substantially expand specialist burn care coverage, improving outcomes for millions.
