Question:
A GPS collected point dataset suffers from high horizontal error.
The best immediate action is:
A GPS collected point dataset suffers from high horizontal error.
The best immediate action is:
Show Hint
Use DGPS to immediately correct high GPS positional inaccuracies.
Updated On: Jun 16, 2025
- Increase the sampling interval
- Correct using differential GPS (DGPS)
- Rasterize the point data
- Smooth using TIN creation
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Differential GPS (DGPS) enhances the accuracy of position data by correcting GPS signal errors in real time using a fixed reference station, making it ideal for reducing horizontal errors.
