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

441
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...

  • To provide a practical tool for land management and soil conservation.

Main Methods:

  • Developed an updated portable field tool (Gulliometer) for enhanced data collection.
  • Implemented a standardized image acquisition protocol for consistent data capture.
  • Utilized an image processing technique for repetitive analysis of gully cross-sections.

Main Results:

  • Laboratory validation showed high precision with error rates below 1%.
  • Field applications in Ontario, Canada, demonstrated practicality and effectiveness in diverse conditions.
  • The integrated approach successfully quantified ephemeral gully erosion.

Conclusions:

  • The developed methodology offers a precise and effective solution for measuring ephemeral gully erosion.
