Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

80
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...

Thematic Layering in GIS

91
In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

GIS Software, Hardware, and Sources of GIS Data01:23

GIS Software, Hardware, and Sources of GIS Data

227
A Geographic Information System (GIS) combines specialized software and hardware to effectively manage, analyze, and present spatial and related data. GIS software includes critical functionalities such as a user interface for easy navigation, database management tools for handling spatial and attribute data, and data retrieval features for efficient access. Analytical tools transform raw data into insights, while display functions produce maps and reports in various formats for effective...

Levels of Use of a GIS01:29

Levels of Use of a GIS

111
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 GIS01:28

Introduction to GIS

217
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...

Issues And Trends In Healthcare Delivery System

5.9K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

  • Computer Science
  • Information Systems
  • Cybersecurity

Background:

  • E-governance adoption is driven by digital technology evolution, necessitating inclusive models with integrated services.
  • Current e-governance systems often struggle with bureaucratic processes and secure distributed data sharing for citizen information.
  • Citizens face challenges in verifying confidential information across European countries due to fragmented systems.

Purpose of the Study:

  • To propose the sinGLe sign-on e-GovernAnce Paradigm based on a distributed file-exchange network for security, transparency, cost-effectiveness, and trust (GLASS) model.
  • To ensure citizens can control their relationship and data sharing with governmental agencies.
  • To demonstrate a novel approach for secure storage and retrieval of verifiable credentials.

Main Methods:

  • Integration of a permissioned blockchain with the InterPlanetary File System (IPFS).
  • Encryption and secure storage of verifiable credentials (e.g., academic awards, ID documents) within IPFS.
  • Implementation of access control mechanisms allowing only trusted users to retrieve encryption keys from the blockchain.

Main Results:

  • A demonstrator was created, proving the feasibility of the GLASS approach.
  • The proposed method enables secure encryption and storage of verifiable credentials on IPFS.
  • Access to encrypted credentials is controlled via blockchain-based key distribution.

Conclusions:

  • The GLASS model offers a secure, transparent, and cost-effective solution for e-governance.
  • Integrating blockchain with IPFS enhances citizen control over their digital identities and governmental data.
  • The developed demonstrator validates the potential of this approach for real-world e-governance applications.
