Multiple on-board components and numerous critical data communication settings present a significant risk of downtime through equipment setup issues. The unique CEE echo sounder technology reduces the potential for field problems: all components are integrated and installed in a single enclosure, simply turn on the power and start surveying — even when using a local RTK base station. The removable echo sounder and positioning system is fully interchangeable for manned boat surveys.
As soon as the USV data module is powered-up, the survey data are ready on the shore for acquisition. For security and flexibility, all survey data — position, bathymetry, and quality control information — are recorded on-board for complete redundancy, ready to be directly imported into survey software as needed.
It requires no additional software to operate, no troublesome remote PC on the vehicle, no additional radio communication equipment, and no additional training is needed. The operator simply selects whether the survey lines are run manually or automatically with a mode switch on the hand controller.
The entire bow portion may be easily removed for transportation. This wonderful design feature offers users the benefit of a long hull high performance without the drawbacks in portability. As the bow is completely sealed, it also provides emergency flotation that ensures the boat cannot sink even if the entire rear segment is filled with water.
Our goal is to make the survey process as simple as possible from setup to data editing. Several antennae options are available to maximize operational range, up to and beyond 1km 3,ft distance. No long interruptions.
The fiberglass hull is exceptionally strong, and stainless steel skids screwed to the hull make easy deployment and recovery with no parts to snag or snap. Over sized motors drive heavy duty prop shafts with a belt link, providing significant protection against damage should debris become caught in the props. The optional long range performance antenna platform raises the data and navigation RC antennae up off the deck level, of vital significance for avoiding destructive interference of USV to shore radio signals over the water surface.
Hydrographic surveys in the mining environment presents a good example of the value of the CEE-USV for unmanned tailings and settling pond bathymetry. With limited or no access for a manned boat, shallow and narrow cross sections, the remotely-operated system brings maximum value for this operation.
With a pH of under 3. LiDAR systems at: www. Ideal for repeating surveys or covering large areas, bathymetry results from an autopiloted survey are at the peak of what is achievable. The basic positioning solution is a highly flexible system that may be specified at several levels of accuracy depending on the geographic location and project requirements.Much as 3D mapping works above ground to calculate the size of an area, height of hillside etc.
I want to do the same underwater. Share Tweet. Views: No way to do this with camera only. There is a possibility from airborne laser for shallow water, but this thing is so heavy for a drone, I only heard of real plane doing that.
Echo sounder is still the only way to go. I do drone mapping and also bathymetric survey with multi-beam echo sounder and the typical gap is 0 to meter depth where it is too shallow for the boat, and not visible from the sky.
Bodies of water do not do well with photogrammetry. There are no tie points on the surface of water for the model to photogrammetrically render itself. Try a test over a pool of water and you will find Mount Everest suddenly appears!
But it is not very accurate. Have you seen this done before? Pascal P. A lower frequency laser at about nm will penetrate the water surface. So look for a lidar system that is a lower frequency than the standard nm. I don't know if there's one available commercially for UAV's but that's what you'd use from a manned plane. As much as I want to give you aerial options.
I would rather save you some time! Our team has done months of research on this topic doing water supply assessments based on snowmelt and reservoir volume. The short answer is no - hydrographic surveys are most effectively conducted using types of sonar.
The reason is because trying to read an accurate measurement of a signal traveling through air However, aerial can be highly effective when accompanying hydrographic because depending on the nature of the mission, you will likely need to capture topo from the shoreline.
For example, somebody like the army corps of engineers may want a volumetric assessment of "full pond". This includes the shoreline topos. Anything over a few feet deep in moderately clear water is going to be very tough. Optical solutions are not the tool for the job. Additionally, you will need GCP's if you are doing a survey of any engineering quality. This will likely entail having a survey team on the ground anyways if they already have iron set in the area.
You will pay big bucks for this though and it is far from an "off the shelf" product.
Drones: The Next Great Leap in Hydrography
A partnership with a research institution or an intimate understanding of the technology is required.The hydrographic drone HyperBathy30 is designed for maximum efficiency in river flow measurement. Lightweight and resistant, it can be used very easily in various mission conditions: lagoon, harbour, river or still water.
It is compatible with a wide variety of ADCP sensors or echosounders. The hydrographic drone HyperBathy30 weighs only 17 kg. Equipped with side handles, it is manageable and usable by one person. This allows you to reduce your staff costs in the field. Thanks to its compactness only cm in lengthit is easily transported in the car trunk. With a payload of up to 10 kg, you can carry a wide variety of sensors.
Hydrographic survey marine drones
Moreover, the drone implementation is realized in 10 minutes. The hull is made from carbon fiber and glass. This makes it particularly resistant to corrosion, waves and heat.
This robust design allows you to use your drone in different aquatic environments such as rivers, lagoons, or harbours. The HyperBathy30 drone is piloted thanks to a radiofrequency communication of up to 2 Km.
It has a long battery life of 6 hours average consumption at a speed of 1. From the mission planning software with the automatic mode, you define the zone on which you want to perform your operation. After transferring data to the drone, it will execute its mission completely automatically. The manual mode also remains available with a radio remote control. Thus, you guarantee the operator safety, and you reduce the personnel and material costs.
This gives you increased productivity compared to traditional methods. Moreover, thanks to its small size, this marine drone can access shallow waters and make you benefit from more missions.
The HyperBathy30 is equipped with a waterjet propulsion. This means that the water is pumped under the boat and then expelled at a high speed behind it.
It adapts to various current conditions. Thanks to measuring instruments such as the flowmeter or current meter ADCPit is possible to measure the water flow and their effects. The water flow measurement allows hydraulic structures operators irrigation systems, hydroelectric installations, reservoirs… to control agriculture, prevent floods, but also drive energy. The need for this technique is reinforced by the current environmental conditions with global warming.
Water flow measurement helps protect goods, people and heritage. Thanks to a long-term observation, it is possible to know the evolution of the river regimes, to prevent the floods and to sensitize the population to the natural risks.
Bathymetry is the science that corresponds to the depth measurement. This technique collects information on marine environments and soil topography below the surface of the water using an instrument called an echosounder. Bathymetry is used in different use cases: — Ensuring the navigation safety harbours, waterways… — Monitor dragging works — Conduct hydrographic research — Mapping the seabed — Follow the banks erosion — Calculate volumes — Identify rock outcrops.
The SuperBathy is an automatic catamaran drone with a dual technology of aerial or aquatic propulsion.Drones are continually proving to be powerful commercial tools, simultaneously providing adopters with leaps in efficiency and safety. The surveying and mapping industry is no exception. With their ability to capture data from above, drones have been successfully integrated into surveying workflows to perform land surveys, photogrammetry, 3D mapping, topographic surveying, and more.
Surveying is the precise science of determining the positions of, and the distances between, points in 2D and 3D space. Surveys provide critical information that enables informed decision making ranging from construction site planning, to design and upkeep of infrastructure, to delineating cadastral property boundaries, and more.
Unmanned Aerial Vehicles, or UAVs, excel at rapidly acquiring data from vantage points inaccessible to humans. When surveying challenging terrain, drones make it no longer necessary for human operators to physically access and measure points in hazardous or difficult-to-reach locations.
Additionally, while traditional surveying methods require meticulous measurement, preparation, and planning, drones can capture comparable data in dramatically shorter timeframes. Depending on your choice of data sensors and surveying software, drone surveying can produce a variety of deliverables with use cases in many industries.
In construction and project management, drone surveying can provide critical data that goes hand in hand with Building Information Modeling BIM. At each stage of the construction process, high-resolution 3D photogrammetric or laser models captured by drones can be overlaid on and compared with pre-planned BIM objects. This allows for discrepancies between plans and reality to be identified.
Early detection of these issues can reduce construction error, omission, and re-work, and this project oversight has made drones an essential part of modern construction.
Before adopting drones into their workflows, many surveyors ask about aerial surveying accuracy. What degree of accuracy can drone surveying techniques achieve?
Surveying drone solutions can produce surveys with different degrees of accuracy, depending on the requirements of the project. For some applications, like checking crop growth, or construction progress, high relative accuracy is sufficient. For other jobs that also require high absolute accuracy, there are drones equipped with real-time kinematics RTK and post-processing kinematics PPK capabilities.
When paired with a few GCPs, survey-level accuracy can be achieved. With all the benefits drones bring, and with so many surveying drone options to choose from, it raises the question, which is the best drone for surveying?
The answer ultimately lies with your priorities. Surveying accuracy requirements, data sensors, and cost should all come into consideration. Click here for more detail on the best UAV surveying and mapping solutions.
We hope this article has helped you realize just how much drones can enhance your surveying potential. Drones allow surveyors to reach new heights in terms of the speed, safety, and ROI they can achieve.

As Chartered Surveyors, the outputs we can achieve are highly accurate, reliable and repeatable and can be coupled with traditional survey techniques. This allows us to use the technology as a tool to enhance our deliverables, whilst maintaining the accuracies required of a professional survey for engineering design purposes.
There are many companies who would promote the use of UAV surveys and the ability to operate a drone commercially as the ability to undertake topographic surveys at a reduced cost but this is not the case. Such approaches are likely to result in an unreliable survey output which, at best, would be unfit for purpose and full of distortion and, at worst, may be disastrous!
Specific extents where more detailed survey information is required can then be identified and the best approach to meet project requirements can be adopted. Examples of approaches available are:. The Civil Aviation Authority, in exercise of its powers under the Air Navigation Orderhas permitted Aspect Land and Hydrographic Surveys Limited to conduct commercial operations using multirotor and fixed wing UAVs not exceeding 7kg, at a height not exceeding ft above ground level and at a distance beyond the visual line of sight of the person in charge of the aircraft to a maximum range of m.
We have a number of fully qualified pilots who have all undertaken and passed the technical and practical assessments required by the CAA to allow them to operate our multi-rotor and fixed wing UAVs commercially.
Part of this process involves the formulation of an Operations Manual, approved by the authority, which defines the procedures and processes which must be adhered to at all times to ensure safety and legal compliance with aircraft legislation.
