Underground Utility Mapping with Confidence 101: The Basics to Improving Utility Positioning
How can you improve the accuracy and reliability of utility mapping data?
Join us to explore the positioning methods used to support modern utility mapping workflows. We’ll review GNSS/GPS fundamentals, compare Base & Rover, RTK, RTN, and VRS workflows, and discuss the accuracy expectations and limitations of each approach.
Participants will learn best practices for subsurface locating and mapping, understand common sources of positioning error, and gain practical guidance on selecting the appropriate positioning method based on project requirements, risk levels, and desired outcomes.
In this webinar, we will cover:
- Why subsurface positional accuracy matters
- GPS/GNSS fundamentals and correction methods
- Base & Rover, RTK, RTN, and VRS workflow comparisons
- Accuracy expectations, limitations, and error sources
- Best practices for utility locating and mapping
- Aligning positioning methods with project risk and accuracy requirements
