Nearview has gone #hyperspectral! In partnership with Schoodic Institute at Acadia National Park, we are flying and mapping salt marsh ecosystems on the coast of Maine with a Headwall VNIR system, high-resolution RGB camera, and lidar. Can you see the difference? While the RGB provides higher resolution, the 136 spectral bands of the VNIR system more easily distinguishes vegetation types and species. Nearview appreciates the support of GRYFN in this survey effort. Our imagery will be used to classify and monitor salt marsh vegetation. The data will also be used to build out our spectral library (https://lnkd.in/ebWdtBgx). We will be releasing the next speclib within a couple of weeks, which will feature spectra for seaweed, salt marsh plants, seagrasses, and intertidal sediments. This open-access library is the only source of hyperspectral ground validation data specific to intertidal and coastal ecosystems. We will announce the upcoming release soon! #remotesensing #dronesforgood #uas #lidar #saltmarsh #marinescience #marineecology #intertidal #earthobservation

Title: Mapping Disturbances from Hurricanes and Lightning in Mangrove Forests Using LiDAR in Everglades National Park Description: This project utilizes LiDAR data to identify and map disturbances caused by hurricanes and lightning strikes in the mangrove forests of Everglades National Park, Florida. Using high-density LiDAR point clouds from a 1 km × 1 km study area near Shark River, the project demonstrates a comprehensive process in ArcGIS. The aim is to provide a more efficient and effective method than traditional field surveys or optical remote sensing, which lack tree height information. This approach helps understand the environmental impact of disturbances and aids in the management and conservation of mangrove ecosystems. #LiDAR #RemoteSensing #MangroveConservation #EnvironmentalImpact #ArcGIS #ForestManagement #HurricaneImpact #LightningStrikes #EvergladesNationalPark #GIS #EcologicalResearch #DataScience #EnvironmentalMonitoring #SpatialAnalysis #ConservationScience #GeospatialAnalysis

Topographic Lidar vs Bathymetric Lidar (By Airborne) Airborne Lidar systems are commonly mounted on either fixed-wing aircraft or helicopters (drones as well). In this configuration, infrared laser light is emitted downward and captured by the moving Lidar sensor. There are two primary categories of airborne Lidar sensors: topographic and bathymetric. Topographic Lidar: Topographic Lidar is employed to create detailed surface models for various applications, including forestry, hydrology, geomorphology, urban planning, landscape ecology, coastal engineering, survey assessments, and volumetric calculations. Bathymetric Lidar: Bathymetric Lidar is specifically designed for water penetration. Most bathymetric Lidar systems simultaneously capture elevation and water depth, providing a comprehensive survey of the land-water interface. During a bathymetric Lidar survey, the infrared laser reflects off both land and water surfaces, while an additional green laser penetrates the water column. Analysis of these distinct pulses aids in establishing water depths and shoreline elevations. Bathymetric information holds particular significance near coastlines, harbors, shores, and banks, and it is also pivotal for locating objects on the ocean floor.

#LiDAR technology can often "see" what the human eye and other technologies can't, and that includes what's happening undersea. Here's how it can view the seafloor in #Australia according to NSW Department of Planning and Environment >>

🎉 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.
