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...

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...

Area of Science:

Social Sciences
Computational Social Science
Data Science

Background:

Recent years have seen widespread protests globally, often coordinated and reported via social media.
The increasing use of social media platforms presents new opportunities for monitoring social and political events.

Purpose of the Study:

To investigate the feasibility of identifying protest outbreaks using quantitative analysis of activity on the photo-sharing platform Flickr.
To explore the potential of user-generated online content as a source for real-world human behavior measurement.

Main Methods:

Analysis of 25 million photos uploaded to Flickr in 2013 across 244 countries and regions.
Determination of the weekly proportion of photographs tagged with "protest" in 34 languages for each country/region.
Correlation analysis between Flickr "protest" tags and reported protest data from The Guardian newspaper.

Main Results:

A higher proportion of "protest"-tagged photographs on Flickr corresponded with an increased number of reported protests.
The study found a significant correlation between online photo-sharing activity and real-world protest events.
Geospatial and temporal patterns of protest tags on Flickr align with documented protest occurrences.

Conclusions:

User-generated photographs on platforms like Flickr can serve as a valuable, low-cost, and rapid data source for monitoring global human behavior.
The quantitative analysis of geotagged and keyword-tagged photos offers a novel approach to understanding social and political unrest.
Online photo-sharing data provides a scalable method for near real-time detection and measurement of collective human action.
