Bathymetry

SPH Engineering offers MBES (multibeam) and three standard configurations of the SBES (single beam) systems, with single and dual-frequency echo sounders. Typical applications:

  • Bathymetry of waterways, lagoons, lakes, ponds, harbors
  • Dredging planning and monitoring
  • Construction planning
  • TSF (Tailing Storage Facilities) monitoring
  • Sediments monitoring

Info

Our drone-mounted echosounder systems have been field-proven across diverse water bodies worldwide, delivering consistent accuracy comparable to traditional boat-based surveys. Independent validation studies confirm that data collected using our aerial systems shows negligible differences from conventional methods while dramatically reducing survey time and operational complexity.

Each system includes carefully selected components that work seamlessly together: survey-grade echosounders with centimeter-level accuracy, the SkyHub onboard computer for reliable data acquisition, precise positioning technology, and comprehensive software for both flight planning and bathymetric data processing. This integration ensures you collect clean, georeferenced depth data that seamlessly incorporates into your existing workflows.

The aerial approach to bathymetric surveying eliminates many traditional challenges - dense vegetation at the shoreline, complicated access to the water, a shallow rocky bottom, fast flows, seaweeds in the water and no direct access to the water. Whether you're mapping construction sites, monitoring dredging operations, or conducting environmental assessments, our echosounder systems provide the data quality and operational efficiency that hydrographic professionals demand.

Frequently Asked Questions

What accuracy can I expect from drone-mounted echosounder systems?

Our systems utilize survey-grade echosounders paired with RTK GNSS positioning, delivering vertical accuracy of ±2.5cm in ideal conditions. Comparative studies between our drone-mounted systems and traditional boat-based surveys show negligible differences in collected data, confirming that aerial bathymetry maintains professional standards while offering significant operational advantages.

What water bodies can be surveyed with drone-mounted echosounders?

Our systems are ideal for surveying inland water bodies such as lakes, ponds, rivers, reservoirs, and tailings facilities, as well as coastal areas like harbors and shorelines. They excel in locations where traditional boat access is difficult, dangerous, or environmentally disruptive. The systems can collect data in water depths up to 200m, depending on the specific echosounder model.

How does the workflow differ from traditional bathymetric surveys?

The workflow maintains familiar elements while eliminating boat-related logistics. Survey planning is performed using UgCS software, with flight lines automatically generated based on your coverage and resolution requirements. During execution, the drone follows the predetermined path while the echosounder collects depth data and the SkyHub computer handles synchronization and data logging. Post-processing uses industry-standard software like Eye4Software Hydromagic, resulting in the same deliverables you'd expect from traditional methods.

What drone platforms are compatible with your echosounder systems?

Our echosounder systems integrate with professional drone platforms, including DJI M300/M350 RTK, DJI M400, Inspired Flight IF1200A/IF800, Harris Aerial H6, and Wispr Ranger Pro. The modular design allows for adaptation to various UAV platforms based on your specific requirements for flight time, payload capacity, and operational conditions.

What training and support do you provide for echosounder system operators?

We offer comprehensive training programs covering system setup, calibration, flight planning, data collection protocols, and basic data processing. Our support continues beyond training with technical assistance for field operations and data interpretation. Most professionals with basic drone experience can become proficient with our echosounder systems after completing our structured training program.
