Hope this helps.The NEXUS 800 powered by HYPACK is a full end-to-end solution that represents a new paradigm in Unmanned Aerial Vehicle (UAV) data collection by seamlessly harmonizing LiDAR data with photogrammetry. Powered by HYPACK-HYSWEEP mapping software, the operator can plan, acquire, and process the LiDAR and Photogrammetry data onboard a high powered Windows PC and high performance UAV allowing for rapid analysis, product creation and export to a variety of CAD and GIS formats.
Additionally, you will need separate software to process the sonar readings. Engineered for partners and resellers in the remote sensing industry, the Remote Sensing Payload Instrument, or RESEPI®, is a combined Dual Antenna GNSS-Aided Inertial Navigation System, datalogger, LiDAR, camera and communications system that allows for the real time and post-processed generation of point cloud solutions. The EU D32 works great with hypack and hydromagic, allowing full water column review. It features simultaneous operation of both 30khz and 200khz which is useful for bottom composition mapping, sediment buildup analysis etc.
The EU D32 is a professional grade dual-frequency sonar transducer. All sold drones undergo detailed testing tests and drive units are initially tested on the dynamometer. The boat drones are like $30k+, rather large, and there is very little overlap with the UAV systems we are most familiar with. EU D32 Dual Frequency Single Beam Transducer. There are boat drones available from some companies but we found that unless your company is exclusively focused on hydrology, you will see greater fiscal returns buying a $1,500 aluminum jon boat, a trolling motor, and renting a survey unit for each mission.
A partnership with a research institution or an intimate understanding of the technology is required. You will pay big bucks for this though and it is far from an "off the shelf" product. The long answer is that you should be able to find solutions using certain forms of radar with heavily modified and highly specific parameters to correct for the water/air interface. This will likely entail having a survey team on the ground anyways if they already have iron set in the area. Optical solutions are not the tool for the job.Īdditionally, you will need GCP's if you are doing a survey of any engineering quality. Anything over a few feet deep in moderately clear water is going to be very tough.
For example, somebody like the army corps of engineers may want a volumetric assessment of "full pond". 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. The contests categories include Wedding, Nature, People, Urban, Animals, Abstract and Sport for single still images. > water + particulates + turbidity can heavily distort your data. The Drone Photo Awards have announced the 2021 winners. The reason is because trying to read an accurate measurement of a signal traveling through air. The short answer is no - hydrographic surveys are most effectively conducted using types of sonar. 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. Army Corps of Engineers is looking to hire an engineering technician to manage the districts unmanned aerial systems operational program and technical activities. Unmanned Underwater Vessels Response (small platforms) Deepwater high resolution mapping.
As much as I want to give you aerial options.
