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...

Field Application of Global Positioning System

Field Application of Global Positioning System

The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...

Introduction to Global Positioning System

Introduction to Global Positioning System

The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Types of Global Positioning System Surveys

Types of Global Positioning System Surveys

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

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...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Urban Planning
Geographic Information Systems (GIS)
Public Health

Background:

Traditional methods for assessing community resource accessibility (e.g., travel time buffers) have limitations in accounting for destination quality and varied travel modes.
Understanding resource access is crucial for addressing equity issues within communities.

Purpose of the Study:

To develop and apply a novel methodology for creating utility-based accessibility measures for community resources.
To assess the equity of access to parks, libraries, and grocery stores across different income levels in Utah County.

Main Methods:

Utilized passive location-based services data to model destination choices for community resources.
Developed utility functions sensitive to destination quality, continuous travel impedance (multiple modes), and traveler sociodemographics.
Applied the developed measure to analyze spatial and socioeconomic disparities in resource access.

Main Results:

Identified significant discrepancies in resource accessibility across various income levels in Utah County.
Demonstrated that utility-based accessibility measures reveal different patterns of inequity compared to traditional space-based analyses.
Highlighted the importance of considering destination quality and travel impedance in accessibility studies.

Conclusions:

The proposed utility-based accessibility methodology offers a more nuanced understanding of resource access and equity.
Findings underscore the need for targeted interventions that consider socioeconomic factors and resource quality, not just spatial proximity.
This approach can inform more effective urban planning and public health strategies to promote equitable resource distribution.
