This method uses a single sounding device to collect accurate depth measurements and tie them in with RTK-GPS systems. Data points collected with this system use a greater degree of interpolation to create a 3-dimensional model; however, it can be very cost effective in gathering important sounding information.
Advantages of Single-Beam Surveys
- Cost Effective
- Fewer Data Points, Relatively Simple Data Processing
- Easier Mobilization
- High Accuracy Data Collection
