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

172
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...

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...

Selected Data About Geographic Locations

71
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...

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 Global Positioning System

146
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,...

This study introduces a "visitor census" using mobile data to enrich traditional census information. It incorporates human movement patterns to provide a more dynamic understanding of socio-demographics.

Area of Science:

  • Socio-demographics
  • Human Mobility
  • Data Science

Background:

  • Traditional census data offers valuable socio-demographic insights but often treats units as static.
  • Existing data products overlook the interactions and mobilities of individuals within census units.

Purpose of the Study:

  • To introduce a novel
  • visitor census
  • dataset by integrating human visitations from mobile positioning data.
  • To enrich traditional census data with dynamic socio-demographic information based on observed mobilities.
  • To bridge the gap between aggregated census data and individual-level analysis using digital traces.

Main Methods:

  • Identification and validation of potential home locations for 3.58 million anonymous mobile phone users across seven U.S. metropolitan areas in July 2021.
