Technology Limitations in Practice

Technology Limitations in Practice

Overview

Professional practice requires understanding when technology can be relied upon and when its limitations affect results. Proper application of technology includes recognizing and managing its constraints.

Learning Objectives

  • Apply technology appropriately
  • Recognize limitation impacts
  • Communicate constraints to clients
  • Verify technology-derived results

Key Concepts

Appropriate Application

Matching technology to task:

  • Accuracy requirements vs. capability
  • Environmental conditions
  • Time and cost considerations
  • Verification requirements

Limitation Management

Dealing with constraints:

  • Understanding error sources
  • Quality control procedures
  • Independent verification
  • Conservative estimates

Client Communication

Explaining technology issues:

  • Accuracy expectations
  • Limitation impacts
  • Uncertainty in results
  • Alternative approaches

Verification Strategies

Confirming technology results:

  • Independent measurement methods
  • Check shots and redundancy
  • Comparison with known values
  • Reasonableness assessment

Key Terms

  • Accuracy Specification: Stated performance capability
  • Uncertainty: Range of possible true values
  • Verification: Independent confirmation of results

Practice Questions

  1. How should technology limitations be factored into accuracy statements?
  2. What verification should be performed on GNSS-derived coordinates?
