or multibeam. The primary requirement is that the data is dense enough to support the 3D reconstruction process.Supporting Structure From MotionBefore adding functionality for creating new meshes, Fledermaus supported the importing of meshes created using Structure From Motion (SfM) techniques in 3rd party software, such as Agisoft Metashape and Pix4D.  Users desired improvements for better handling of large meshes, and wanted the same functionality they were used to when working with gridded surface. This included operations such as applying color maps, measurement tools, and interactive profiling

MSI completes 'Deepest, Longest Moorings' to Date

buoy to measure meteorology, waves and current profiles as well as an I-type mooring to measure full water column current profiles and water quality.Because the top of the I-type mooring needed to be near the surface, special attention was paid to the mooring design.This was modeled using third party software to ensure that the instruments remain at their intended depths, taking into account the type of rope used for the mooring, as well as the expected metocean conditions on site.Data from the surface buoy is being transmitted in real-time via the Inmarsat DataPro service where it is displayed on

image data is also tagged with position information, ping numbers and time and can also be saved to a catalog for later manipulation. Since the saved data is three dimensional, additional views and measurements can be made, color scales adjusted and results can be exported for import into 3rd party software.   Conclusion The wreck of the J.E. Boyden has been imaged using a new 3D sidescan technology introduced by Ping DSP that provides geometrically correct high resolution three dimensional imagery and provides a significant step forward in comparison with conventional 2D sidescan imagery

a feature filter for automatic filtering of vertical structures as well as a new user friendly graphical user interface with an initiative design. The software offers real-time processing and a series of automated filters which deal with complex survey situations. The system requires no third party software packages to operate although interfaces are available to all major packages.    The software additionally works with the re-designed GeoSwath 4 deck unit which is a smaller modern design nearly half the weight and height of its predecessor

automated for easier operation, helping surveyors to deal with complex survey situations, Kongsberg said. The new GS4 software has been specifically designed for the system and features real time processing and new automated filters. Although interfaces are available to all major packages, no third party software is needed to deliver accurate results. The software includes 64-bit acquisition and processing, improved graphics, new file formats and many additional improvements that make the system faster and easier to use

, and to build custom solutions that address those needs. Deep Ocean Engineering’s in-house engineering team in Silicon Valley creates solutions that utilize their proprietary drone vehicles as a platform, and equips them with best in class components from a variety of manufacturers of third party software, video, sonar and manipulators.   Deep Ocean Engineering specializes in engineering and designing inspection class underwater and surface drones, including its full line of Phantom remotely operated vehicles (ROV) and unmanned surface vehicles (USV).   Recently, Deep Ocean Engineering

, can be used to detect leakage while elsewhere the settings may be tailored to recognize collision. While it is not possible to carry out exact measurements, it is possible to make estimates based on what else is in the picture." While these apps will be available to users, and that third-party software developers may launch others, Imenco anticipates that some companies will integrate the platform into their own in-house systems. "For this reason, we have made it an open source system," said Wulfsberg. "It is likely that operators will have a good understanding about what they
