Tip for #LaserScanning: If you’re scanning topography, YOU BETTER USE CONTROL POINTS!! And honestly, you better be using control points anyway. Cheers!

🌟Photogrammetry for Slope Stability Assessment 📸 🔍Slope stability assessment is crucial for mitigating the risks associated with landslides and ensuring the safety of infrastructure and communities. Photogrammetry offers several invaluable applications in this field: ✨1-Detailed Terrain Modeling: Photogrammetry enables the creation of highly detailed 3D models of terrain, allowing for accurate analysis of slope geometry, surface features, and potential instabilities. ✨2Monitoring Changes Over Time: By comparing 3D models created at different times, photogrammetry helps in monitoring changes in slope morphology, identifying areas prone to erosion, landslides, or other instability issues. ✨3-Identification of Critical Features: Photogrammetry facilitates the identification and mapping of critical geological features such as fractures, faults, and joint sets, which play a significant role in slope stability assessment. ✨4-Quantitative Analysis: Photogrammetry provides quantitative data on slope angles, heights, and surface roughness, which are essential parameters for assessing slope stability and identifying potential failure mechanisms. ✨5-Early Warning Systems: By integrating photogrammetry with real-time monitoring systems such as drones or satellite imagery, early warning systems for slope instability can be developed, helping to mitigate risks and prevent disasters. 🔍In summary, photogrammetry is a powerful tool for slope stability assessment, providing detailed data and insights crucial for identifying potential hazards, monitoring changes over time, and implementing effective risk mitigation strategies. #Photogrammetry #SlopeStability #LandslideRisk #GeotechnicalEngineering #EarthScience #RemoteSensing #LinkedInPost

Topography on corridor

GEOSAT's mosaic technique involves stitching together multiple #SatelliteImages to create a complete and seamless view of broad regions that cannot be captured in a single image due to sensor footprint limitations. We combine images taken at different times to create a composite view that reveals changes in an area over time. Orthorectification is essential for these images because it corrects distortions caused by terrain and sensor angles, ensuring that they accurately represent the Earth's surface.

This one is close to home 🇿🇦 The evolution of the failed Jagersfontein Tailings Dam in South Africa reminds us how valuable it is to have objective data about past site decisions. Many older #tailings facilities lack complete records, but satellite imagery can fill those gaps. The topographic surfaces (DEMs) in this GIF date back to the 1970s, produced from Keyhole, WorldView, and Sentinel satellites. If you're interested in a historic reconstruction of your site, please pop me a DM or email. #mining #tailingsmanagement #satelliteimagery

Definitely, the connection between #SurveyEngineering and #Geotechnical is real, and that's why I am convinced is a perfect and 100% complementary match...the use of terrestrial #photogrammetry to create accurate face maps is getting every day more and more extended, and the results are impressive...

Turning Cartography into passion have helped me better understand maps.

Working on another photogrammetry asset pack. Aiming to get this done this month. This one's focus is lots of boulders, rock piles, moss and small ground cover plants. #gameart #Unreal #photogrammetry

We're excited to announce a major innovation! Haley Ward now provides fast, efficient workflows for drainage and upslope basin analysis using high-resolution elevation data. Most sites have public LiDAR coverage, allowing us to quickly deliver hydrographic and topographic insights with much greater detail than standard USGS datasets. Our process is mostly automated and generates: ·        Watershed/basin boundaries  ·        Flowlines and drainage networks  ·        Outfalls and sub-catchment areas  ·        Upslope landcover analysis ·        Detailed topographic maps with one-foot contours, shaded relief, and slope gradients With added project costs normally under $1k, it's an affordable solution for enhanced site planning! #haleyward #GIS #workflows #topographicmaps #GISmapping
