Utah Geological Survey’s Post

We're excited to introduce our new series: Ask Maya about Nature! 📢 This series will explore the complexities of our natural world through the lens of geospatial technology. Join us as we explore questions where geospatial analysis and Nature-based Solutions meet. 🤝 Stay tuned for insights from answering questions such as: 🔍 Why is it essential to conduct a 10-year land cover check? 🌳 What is the NDVI and how is it relevant to Nature-based Solutions? 🛰️ What are PDSI, Landsat, Sentinel, LiDAR, and PALSAR? – We'll break it down for you! 💚 And much more! Follow our page to stay up to date! 👀 #AskMaya #YourGeospatialAnalyst #GIS #GenAI #GeospatialProcessAutomation #NaturebasedSolutions #NaturalCapital

🌟Underwater LiDAR:🌟 💡Underwater LiDAR is marine research and exploration by providing high-resolution 3D maps of underwater environments with high detail and accuracy. 🌟 Key Benefits of Underwater LiDAR: 💡1-Precision Mapping: Captures detailed 3D models of underwater landscapes and structures with high-level accuracy. 💡2-Enhanced Exploration: Enables scientists and researchers to study monitor changes over time, and discover hidden treasures with unparalleled clarity. 💡3-Efficient Surveys: Streamlines underwater surveys and inspections, reducing time and costs associated with traditional methods. 💡4-Archaeological Discoveries: Unveils submerged archaeological sites and artifacts, shedding light on our maritime history and cultural heritage.

This technology is very interesting since LiDAR problem is penetrating water bodies. Although it has the ability to penetrate water, its range is very shallow. I am very curious and interested on how the mechanics of the LiDAR and how accurate the depth that it can produce.

A highly recommended method for survey of rivers which are susceptible to flooding and in high risk position.

Important insights about critical geo-data underpinning disaster risk assessments. Making sure we understand the nuances. Really good work. #disasterriskreduction #climateadaptation #DEM #earthscience #awesome;)

If you use a global #DEM (e.g. SRTM) as #topography data for #flood modelling, you may be interested in our recent paper. We assess five contemporary options (FABDEM, Copernicus DEM, AW3D30, NASADEM & SRTM) using a very large reference dataset (65 airborne LiDAR surveys) representing flood-prone environments globally. TL;DR - the Copernicus DEM (GLO-30 in the figure) is generally a big improvement over older DEMs (SRTM, AW3D30) except under forests (hard for X-band radar to penetrate), and FABDEM achieves further improvements using #ML (random forest models) to predict corrections for forests & built-up areas. More nuance & details in the (open-access) paper linked below. Thanks to everyone on here who helped by suggesting reference data sources, to my co-authors at RMIT University, Simon Jones & Karin Reinke, and to Natural Hazards Research Australia for their scholarship support!

The US Geological Survey (USGS) and its partners have officially launched World Lidar Day, which will take place on February 12th during the Geo Week Conference. 🚀 Lidar technology plays a crucial role in mapping and understanding our planet's surface, and this initiative aims to raise awareness about its importance and potential applications. 🗺️💡 To learn more about this event and how lidar is revolutionizing geospatial data collection, check out the article below! 👇 https://lnkd.in/gDzGpc-z #WorldLidarDay #GeoWeekConference #LidarTechnology #GeospatialData #USGS #GeospatialTechnology #GIS

Based on a permanent TLS station (measuring forest every hour, data resemble drone laser scanning (in geometry) since TLS is placed 30 m above ground level): - Hyper-temporal LiDAR time series captures phenological characteristics of tree species. - Tree-wise phenological dynamics are species-specific and support species classification. - Late autumn and optionally late spring LiDAR data support best species classification (single wavelength system). https://lnkd.in/dDGw9F_C

⚠Geo Week Attendees⚠ Happy Monday! Booth #817 is open and ready to take on the day. Make sure to stop by our talks today, information below. From the Beach to the Blue (11:00 am - 12:30 pm) - Room 504 - "This conference session underscores the importance of having seamless elevation data to link terrestrial and ocean mapping for key decisions in the coastal zone." Topobathy Lidar: Specifications and Experiences (2:00 pm - 3:30 pm) - Mile High Ballroom 2A - "Hosted by the ASPRS Bathymetric Lidar Working Group, this session will begin with presentations highlighting projects conducted in diverse environments (coastal, bay, estuarine, and riverine) and will conclude with a discussion of bathymetric lidar specifications and best practices proposed by federal and industry partners." #GeoWeek #GeoWeek2024 #Denver #GIS #Geospatial #RemoteSensing #ASPRS #BeyondEngineering #NV5Geospatial #NV5
