🎉 The new YellowScan Navigator is here! YellowScan's newest and most innovative product, the Navigator is a bathymetry LiDAR system that enables shallow water terrain topography mapping as well as water surface capture. It is perfect for non-navigable areas (shallow to medium depth waters) and where the costs of using an aircraft for scanning would be too high. Specifications: ➡ Precision and accuracy: 3 cm, ➡ Maximum depth: 2 Secchi, ➡ Operating altitude: between 25 and 100 m, ➡ 44° scanning FOV, ➡ Autonomy of 40 minutes. Its applications are in the fields of coastal oceanography, safety of hydraulic structures, natural disasters, underwater archaeology, surface water hydrology, dredging and marine works, but it can equally well be used for different types of analysis in rivers and lakes.

Data Dive: A view looking north east at the entrance of Arch Canyon. The image was created from the lidar bare earth model colored by elevation. Data were collected to aid USFS Region 4 in assessing the topographic and geophysical properties of the study area to identify landscape scale information on cultural resource sites and to provide information for assessing and managing vegetation, fire, and recreation activities. #ArchCanyon #Utah #GIS #Lidar #Topographic #USFS #BeyondEngineering #NV5

TODAY is #gisday and to celebrate, we wanted to give you a sneak peak into some of the work our Geospatial Foundations team does with lidar. Wait, what’s lidar, you ask? It’s short for Light Detection and Ranging, and here’s how it works: A sensor that shoots a laser to the ground is mounted on an airplane. We can calculate the distance the laser traveled based on the time it takes to get back to the plane, and we can use that distance to get information about the terrain surface and height of vegetation. Our team uses lidar, in part, to collect detailed information they can then use to map human land-use and natural disturbances, and to quantify vegetation regrowth on these features. This is useful for mapping habitat recovery for threatened species, for example,  like woodland caribou. By understanding the status of caribou habitat, and recovery rates on various habitat disturbance features associated with caribou declines, habitat restoration efforts can be more effectively prioritized. #ABMIatWork #lidar #biodiversity #biodiversitymonitoring #habitat

So we're technically a couple days late on #WorldLidarDay, but every day is lidar day at #KGS. #Lidar (light detection and ranging) is a type of laser scanning that allows geoscientists to make incredibly detailed 3D computer representations of Earth's surface, even in heavily forested areas. KGS researchers use statewide lidar data to identify landslides and sinkholes, develop geohazard susceptibility maps, improve flood modeling, advance resilience planning, and map surface expressions of faults in the New Madrid seismic zone. https://lnkd.in/e8gH-G9g? #geology #geoscience

EAASI Summit Insights: Portugal's Aerial Surveying Initiatives. Paulo Patrício, Head of the Geodesy, Cartography, and Geographic Information Department at the Directorate-General for the Territory – Portugal, provided an in-depth exploration of Portugal's advancements in the field of aerial surveying during the EAASI Partners Summit (Lisbon 21-24 November). LiDAR survey: the agency is set to produce a new Digital Terrain Model, along with various derived products, including vegetation maps managed by the Nature Conservation and Forest Institute. Scheduled to commence in the coming months. Density: 10 points/m2. 🌐 Stay Tuned for More Summit Insights! This post is part of a series sharing key takeaways from the EAASI Summit.

A point cloud captured with a terrestrial laser scanner (TLS) reveals the inside of a cavern at Golden Gate Highlands National Park, South Africa. Within the cavern lies a geomorphological phenomenon called Tafoni, speculated to have formed due to preferential weathering. However, there isn't an accepted theory behind the formation of this cavernous weathering. This was a component of my Honours project, where I evaluated the feasibility of using LiDAR to scan macro and micro geomorphological features. I generated a Digital Elevation Model (DEM) of this phenomenon and calculated the volume of the total weathered material. This might provide insight into the reasons behind the formation of this feature and allows for the rapid and accurate measurement of complex geomorphological features. #LiDAR #Geomorphology #Geomorphometry #MorphometricAnalysis #3Dscan #Surveying #TLS

In the quest to unravel the mysteries beneath our planet’s water bodies, #topobathymetric #technologies emerge as a beacon of #innovation. Among them, #Lidar (light detection and ranging) and #sonar #sensors mounted on uncrewed aerial systems (#UAS) are pushing the boundaries of what is possible. Offering unprecedented #precision in #mapping #underwater landscapes, these technologies are revolutionizing #hydrography, environmental monitoring and coastal management. This article delves into the latest advancements in topobathymetric Lidar and sonar, highlighting their critical role in understanding and protecting our #aquatic #environments. From its origins to its future potential, we explore how Lidar #technology illuminates the depths like never before. #Bathymetry, the study of underwater #topography, plays a crucial role in various fields by mapping the #seafloor to support navigation, scientific research and environmental management. It involves collecting data to create detailed charts used in navigation, to study seafloor profiles for #biological #oceanography, to assess coastal erosion and to monitor sea-level rise. This data is vital for safely managing natural hazards such as floods and river erosion, ensuring navigable waterways, and aiding in the design and maintenance of ports, harbours and urban planning. Topobathymetric data, which merges #topographic and #bathymetric information, further enhances our understanding of both terrestrial and aquatic environments. #mai #marineacoustics #marinescience Salman Bashit Narcisa Pricope, PhD #bottommapping #acoustics #oceanscience #safenavigation https://lnkd.in/eYtr6fan

Blue carbon ecosystems, particularly seagrass meadows, support biodiversity, protect shorelines, and sequester and store carbon. Locating seagrass habitats and measuring their spatial extent is key — but has been difficult with existing methods. We’ve developed and validated an aerial LiDAR approach for mapping tropical seagrass meadows by integrating full-waveform bathymetric LiDAR with multi-spectral imaging. Our paper on this innovative and scalable method is now officially published: https://hxgn.biz/3XKkr8u
