THE SOLUTIONS THAT 4K MAX SIDE SCAN SONAR OFFERS #Klein 4K-MAX is a professional series side scan sonar that combines the patented gap-filling technology of the MA-X View 600 sonar with the enhanced bottom tracking accuracy of a TruBottom™ Tracking dedicated altimeter and an improved nadir gapfiller processing algorithm. The 4K-MAX delivers unprecedented focused 600kHz imagery (equivalent to 900kHz resolution) at an optimized range of 50 meters per side (maximum range of 120 meters per side) with co-registered 850kHz nadir gap-fill data. This is a powerful solution for professional underwater surveys. Problem:  Traditional side scan sonar systems have a blind spot directly below the vessel, known as the nadir gap. Surveying this area requires additional time and effort, impacting efficiency and cost. Solution:  MA-X Technology addresses this issue by providing: • Imaging of the nadir zone: It fills the gap in sonar coverage directly beneath the towfish. • MA-X is TRUE grazing angle sonar: This allows for consistent analysis and interpretation of data across the entire surveyed area owing to the excellent shadow casting and high resolution. • Reduces the need to ensonify the nadir area on adjacent lines: This eliminates the need for extra passes or maneuvers to cover the gap, saving time and money. Benefits: 1. Improved survey efficiency 2. Reduced Vessel fuel savings 3. Surveys completed approximately 40% faster Adapted from #kleinmarinesystems You can order this equipment from us.

Bridge deck delamination surveys traditionally involve the dangerous and manual processes of chain dragging and hammer sounding to detect different sound pings, highlighting potential cracks or air bubbles in the subsurface of the bridge deck. Can improved thermal imaging sensors help automate this process? Seiler GeoDrones recently had the opportunity to assist our customers, Willett, Hofmann & Associates, Inc., by flying a bridge deck in McHenry County, IL. We used the brand new DJI H30T sensor onboard the Matrice 350 to locate hotspots in the bridge deck, indicating potential delamination areas. The new High Resolution mode on the H30T made it easy to identify the hotspots. Within 30 minutes of being on-site, we flew the M350, collected the data, and generated a geospatially referenced "heat map" to easily show all the potential issue areas. We compared the data from the H30T with the manual chain dragging process - the results were very impressive. Below is a side-by-side video showing the infrared and visual data from the delaminated bridge on the left compared to a newer bridge deck on the right. The thermal data was collected after the bridge was surveyed using the traditional methods. The video was captured using the Black Hot temperature palette - warmer areas will appear black, cooler areas will appear white.

A thermal drone inspection of a bridge in order to highlight any cracks or air bubbles in the subsurface. Look at the side by side of the thermal camera vs the regular camera after the original survey was completed. The results are right on target.

In today's post, I am discussing the use of optical flow for processing radar imagery in volcano monitoring. The attached figure shows an interferogram (bottom left) created from the phase component of a Sentinel-1 radar image (PyGMTSAR). In the top right, you can see the displacement measured from the same radar image, but this time processed using radar backscatter imagery with the Akhdefo software. Below is a comprehensive tutorial on processing radar imagery(RockGlacier case study) with Akhdefo software: https://lnkd.in/gfJHtmUY #AkhDefo #Optical flow #Volcano #Monitoring #Landslides #RockGlacier

ALSO: for any regions susceptible to flooding, multiple GPR data passes can collected in parallel to identify areas along a roadway where erosion has occurred. These areas will have inconsistently high void ratios within the base structure and are an early indicator of alligator cracking 🐊, potholes 🛑, and even sink holes 🚧. #publicsafety #infrastructure #roadmaintenance
