Selected Data About Geographic Locations

Selected Data About Geographic Locations

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...

Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

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...

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...

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...

Thematic Layering in GIS

Thematic Layering in GIS

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)...

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...

Area of Science:

Computer Science
Information Security
Geographic Information Systems

Background:

Conventional access control systems struggle with scalability, security, and transparency in distributed environments for geographic spatial data sharing.
Secure and efficient data sharing is critical for urban planning, disaster management, and environmental monitoring.

Purpose of the Study:

To propose a new framework for fine-grained, decentralized, and tamper-proof geographic spatial data sharing.
To integrate Attribute-Based Access Control (ABAC) with blockchain technology and smart contracts.

Main Methods:

The framework combines ABAC, blockchain, smart contracts, and an upgraded Black-winged Kite (UBK) algorithm.
Access policies and audit logs are stored on a private blockchain using a Proof-of-Authority consensus mechanism.
An upgraded Black-winged Kite (UBK) algorithm is utilized for enhanced access control.

Main Results:

The proposed method reduces policy evaluation time by 70% and storage overhead by 52% compared to traditional ABAC.
Achieved 98.2% accuracy in access decisions.
Performance tests indicate linear scaling of evaluation time and storage, suitable for large-scale deployment.

Conclusions:

The integration of blockchain and smart contracts ensures security-auditable and automated enforcement of access policies.
The framework provides a decentralized and tamper-proof solution for sharing geographic spatial data.
The proposed system overcomes the limitations of conventional access control in distributed settings.
