Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device01:30

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 served as...
Methods of Obtaining Topography01:25

Methods of Obtaining Topography

Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...
Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
Topographic Surveying and Contours01:29

Topographic Surveying and Contours

Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...
Dimensions of Health and Illness01:21

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Area of Science:

  • Public Health
  • Environmental Science
  • Geographic Information Systems

Background:

  • Observational audits assess built environment features impacting health behaviors.
  • In-person audits are costly for large or dispersed areas and multiple time points.
  • A more efficient method is needed for broader geographic and temporal scope and standardized assessment.

Purpose of the Study:

  • To evaluate agreement between traditional field audits and image-based audits.
  • To assess the reliability of using omnidirectional imagery for built environment data collection.
  • To determine if image-based audits can replace field audits in public health research.

Main Methods:

  • Compared field audits with audits from archived imagery, new imagery, and Google Street View™.
  • Utilized street segments from St. Louis, MO, and Indianapolis, IN, stratified by socioeconomic characteristics.
  • Assessed agreement using observed agreement and prevalence-adjusted bias-adjusted kappa statistic (PABAK).

Main Results:

  • Mean PABAK values indicated substantial to nearly perfect agreement across all image-based methods.
  • PABAK for archived imagery was 0.78, new imagery was 0.80, and Street View was 0.81.
  • Image-based audits demonstrated high reliability compared to field audits.

Conclusions:

  • Image-based audits are a reliable substitute for field audits in public health research.
  • This method allows for expanded geographic and temporal scope in built environment assessments.
  • Standardized, reliable data collection can improve comparisons across studies and regions.
