Accurate site data 📐 with minimal disruption 🌳 In this use case, aerial mapping wasn’t ideal due to foliage. Instead, PIX4Dcatch’s terrestrial scanning provided the necessary precision to measure the trees accurately. The integration was seamless—data was uploaded directly to PIX4Dcloud and processed in under an hour, with an email received upon completion. It was then exported as a DXF file for CAD as part of planning for the new extension. Read more here: https://hubs.li/Q02TpCM20 #PIX4Dcatch #Pix4D #PIX4Dcloud #CAD #RTK

Laser scanning and photogrammetry of the bridge in Margecany. Processing 3D models of bridges can reveal even the smallest structural flaws and defects that occur in bridge bodies and pose a threat to traffic safety. The result of the scanning is a complete 3D model of the object, capturing the current state down to the smallest details. Processing scans at intervals can also compare models to uncover emerging threats. #LaserScanning #Photogrammetry #BridgeEngineering #3DModeling #StructuralHealthMonitoring #MargecanyBridge #InfrastructureSafety #CivilEngineering

The beloved stockpile, the Site Manager and a Surveyor. A tale of antiquated methods and a heap of sand. Isn’t it a joy when a site manager or foreman casually requests, “Could you ‘quickly’ measure that stockpile?” We’re talking trudging up and down slopes with a GNSS rover, trying to manage a grid of 5x5 meters, but it’s impossible. Sand creeps into your boots, dust sticking to your sweaty face as trucks rumble past—and you pray for a little rain to end the misery. Then, back at the office, it’s time to bust out volumes using only contours, an ancient (18th century, to be precise) method, in your chosen CAD or Surveying software package. All for a volume and model the site manager will glance at briefly to confirm some inkling they had about the quantities—because, you know, it’s a breeze to measure stockpiles. Even after 20+ years, GNSS remains the go-to method for volume measurement unless you have a UAV license, which is a costly and tedious process in South Africa. Enter the 3D terrestrial scanner. Now, I’ll admit that I've made my share of blunders in stockpile measurements, some of which could warrant the ROI on a 3D scanner... I’ve also seen disparities in using GNSS on uneven stockpiles that can lead to significant unaccounted volumes. Most human errors and inaccuracies on site are eliminated by the transparent nature and easy workflow in scanning. Set up in seconds (no levelling needed), press a button, and you're onto the next setup in a minute or so. Millions of points are captured in a precise, up to 10x10 millimetre grid, accompanied by HDR panoramic images. Constructing your 3D point cloud and model in the field guarantees every detail is picked up. To go one step further, you can use an autonomous scanner like the Leica BLK2Go and simply walk where you want to measure—featured in the video by Reality Capture Guy - Thank you Reality Capture Guy. The office workflow is made simple with an interface that has seen much development focussed on user-friendliness. One outcome could be a detailed point cloud accessible to site managers via TruView (free software from Leica Geosystems), enabling efficient basic measurements and collaboration. Note to the reader: No Site Managers were harmed during this writing. https://lnkd.in/dvXRCkV6 #leicageosystems #leicageosystemsafrica #realitycapture #blk2go

Always fascinated by how you can manipulate your imagery before you import into your photogrammetry software and what it can lead to. Using RAW/DNG format gives you great control over the dynamic range and recovery of detail in shadows and highlights but..... A little bit of knowledge invested in how you can play about with mid-tones, colour grading and masking, can make your mesh model pop and look even more realistic or enhance detail. IT also can make you mesh model cleaner. The video below is a true Grayscale model, NOT a video converted to black and white, which I think helps people see more specific detail for #structural inspection, #Heritageconservation, research, and documentation? Why not give your client both? #photogrammetryisphun

Close-range photogrammetry with ViDoc and Pix4D. I'm amazed with the precision of the 3D models as well as 3D accuracy. A cheaper alternative to laser scans (which are basically meant for engineering tasks where millimeter accuracy is needed), makes this technique perfect for "small" areas and GIS tasks like those in the video. #photogrammetry #surveying #ViDoc #Pix4D #mapping

Ever wondered how aerial surveys and 3D data modeling can transform the way we manage coastlines and protect nearby communities? 🌊 With rising sea levels, natural disasters and coastal erosion posing growing challenges, our cutting-edge 3D modelling solution empowers Governments, including coastal LGAs to measure, track, and simulate environmental changes with precision. By combining our advanced aerial survey 3D data with Esri's ArcGIS Pro, we deliver powerful insights that help communities tackle the rising threat of sea levels, help with post-disaster recovery and plan for a more resilient future. 🌍 Check out our Aerometrex video to see how we're making a difference in coastal management: https://lnkd.in/gB3k77Da #AerialSurveys #CoastlineManagement #3DModelling #EsriArcGIS #ArcGISPro #CoastalChange #EnvironmentalSolutions #ClimateResilience #LGAs #3D #2D #Esri #ArcGIS #CoastalErosion Queensland Reconstruction Authority

Capturing test pits in 3d is a great party trick, but do they offer value? Our clients seem to think so because they keep coming back for more! At MacGeo, we use advanced terrestrial photogrammetry techniques to create highly detailed 3D test pit models, capturing sub-millimeter details of visual conditions. These models allow stakeholders to “revisit” the site interactively, while the ground is still open, and better understand the subsurface conditions. Plus, with 2D projections of the pit walls, we can present data with consistent scales, offering an objective source for auditing and enhancing subsurface log accuracy providing added confidence of the ground conditions to our clients. This is particularly useful for pavement investigations where the subsurface stratigraphic profile of constructed layers can vary significantly over short distances. #Innovation #3DModeling #GeotechEngineering #ProjectInsights #MacGeo

Let’s highlight the 3D as-built survey expertise of G Map LLC. #GMap specializes in geospatial services, including 3D laser scanning, mobile mapping, and as-built surveys. * As-Built Surveys: An as-built survey involves capturing accurate measurements and details of existing structures or facilities. It’s critical for construction projects, renovations, and historical preservation. G Map excels in creating as-built plans by precisely measuring both the interior and exterior of buildings using advanced laser technology. These plans show the exact dimensions and layout of structures #3D Laser Scanning: G Map utilizes 3D laser scanners to capture detailed point cloud data of physical objects and environments. This technology provides high-resolution 3D models. #AsBuiltSurveys #GIS #3DScanning #Surveying #Geospatial #oman #gmapoman #construction

Photogrammetry processing is one of the most convenient way in surveying especially when it comes to digital surface modeling, digital elevation model or othormosaic.. etc♻️❤️
