Geiger-mode LiDAR's Digital Terrain Model (DTM) stands out for its unparalleled accuracy, especially in hydro-flattened applications. With high pulse density, multiple returns, and advanced signal processing, it delivers detailed and precise elevation data. This technology transforms floodplain mapping, hydrology studies, and coastal zone management. In urban planning, infrastructure development, and natural resource management, the high-resolution DTM creates precise topographic maps, enabling informed decision-making. In forestry, it provides crucial terrain details for sustainable forest management. Geiger-mode LiDAR DTM is reshaping how we plan, manage, and conserve our environment. At VeriDaaS, we produce DTMs and hydro-flattened DTMs to USGS 3DEP Standards. #LiDAR #DigitalTerrainModel #PrecisionMapping

Geiger-mode LiDAR has many revolutionary advantages. One of these is the ability to capture data with extremely high resolution and detail. This is enabled by using the photon-counting method, which can detect even the faintest returning light signals. This high sensitivity allows Geiger-mode LiDAR systems to achieve very detailed 3D representations of objects and surfaces with an accuracy in the centimeter-range. Such exceptional precision can make a significant difference in improving applications, for example, in utility, forestry, and infrastructure management. See below a comparison between a Geiger-mode LiDAR image with a point density of 30 points/m2 and a conventional LiDAR image with 8 points/m2. The leap in richness of detail is evident! #LiDAR #remotesensing

What is LiDAR? It's a question I still hear often, especially after recent trade shows like the Commercial UAV Expo and Intergeo.

LiDAR, a remote sensing technique, shines a laser light on forests and roads, creating detailed 3D point clouds. This data helps classify both forest and roadside trees. For forests, LiDAR measures tree height, crown size, and density, allowing researchers to distinguish species based on their structure. Roadside trees can be identified by their height relative to the ground (obtained from LiDAR) and location compared to the road network. Machine learning algorithms analyze these LiDAR features to automate classification, creating valuable information for forestry management, road safety assessments, and environmental monitoring.

Two great items I've seen this summer on the use of remote sensing for vegetation / forest management: 1) South SF Bay Municipal AHJ presentation on their drone program by Jackson Ricketts and team: https://lnkd.in/gyK_Kcfw 2) An article in "The Forestry Source" online magazine: "The Death of Sampling and the Rise of Forest Architecture" by Eli Jensen, whose team is executing a 3,200 ac LiDAR scan in a national forest right now as part of an ecological management plan for the area. Link: https://lnkd.in/gJZAcNkN From the article: "Every tree in the project will be scanned with a ground-based backpack LiDAR scanner, segmented, and measured digitally. Silvicultural prescriptions will be applied to the digital model, visualized, and adjusted as needed. The final version will then be marked on the ground with paint." #fireprevention #forests #vegetationmanagement #defensiblespace #sUAS #remotesensing #LiDAR #photogrammetry #GIS

The DJI M300 equipped with the L1 LiDAR sensor is revolutionizing aerial surveys by providing high-precision 3D mapping solutions. The L1 sensor uses LiDAR technology to capture accurate elevation data, even in challenging environments such as dense forests or uneven terrains where traditional photogrammetry struggles. This makes it ideal for applications like topographic mapping, forestry management, infrastructure inspection, and terrain modeling. The L1’s ability to penetrate vegetation and generate detailed 3D point clouds in real-time allows surveyors to capture intricate details with millimeter-level accuracy. This enhances productivity by reducing the need for multiple flights and delivering results quickly and efficiently. #LiDAR #DJIM300 #Surveying #3DMapping #TopographicMapping #DroneTechnology #PrecisionMapping #AerialSurvey #GeospatialTech #InfrastructureInspection

For the Bow and Oldman watersheds in southern Alberta, Hopkinson and his team began planning two airborne missions, one in March and one in April. For the March mission, Teledyne Optech provided a state-of-the-art Galaxy LiDAR system and an operator, while Calgary-based Aries Aviation provided the aircraft. The April mission utilized ULethbridge’s unique Titan Multispectral LiDAR system, with some operational support from Airborne Imaging, also out of Calgary. The LiDAR scans sampled the Rockies from as far south as the U.S. border and north to Saskatchewan Crossing. “The data is confirming that the snowpack in the mountains is not very abundant,” says Hopkinson. “But it’s important to bear in mind that we don’t really have anything to compare it to because we’ve never done this before. All we can do is take our estimates of snowpack water equivalents in the mountains and relate it to similar data structures such as precipitation gauges, snow pillows, field data or runoff records.” While the LiDAR results are comparable to traditional measurements, LiDAR can provide more spatially precise data. “It’s telling us, for example, that the Oldman is showing a lot less snow water in the mountains than the Bow,” says Hopkinson. “But we’d probably expect that anyway just because the Bow is higher in elevation, slightly farther north and has wider mountains. But now we’re able to quantify these things in a way we previously couldn’t.” Hopkinson’s team includes Dr. Celeste Barnes, a post-doctoral fellow who provided project management and data analysis, Jessica Van Gaalen, a master’s student who prepared the data for the cloud computing environment to train an online model and Italo Rodrigues, a PhD candidate who prepared the various layers of data to build an online model of the snow cover. Maxim Okhrimenko, a PhD student and LiDAR lab manager, helped plan the surveys and flying. Farnoosh Aslami, a research associate, assisted with the project by working up data layers as needed. Also working on the project are Dr. James Craig at the University of Waterloo and Dr. Ryan MacDonald (BSc ’06, MSc ’09, PhD ’14), CEO of MacHydro Consultants. “The idea is that we’ll use these data to input into a hydrological modelling scheme to do the forecasting,” says Hopkinson. “It’s innovative because you don’t normally have a spatially continuous map of snowpack that you can then put into a hydrological model. Hopefully, in the next month or two, we’ll get some scenarios from these data that will parallel or supplement the kind of forecasting work the province is doing.” In the future, having more precise snowpack measurements will help guide water management policies and practices."

So pleased to support this important work by Chris Hopkinson at The University of Lethbridge in Alberta. “The data is confirming that the snowpack in the mountains is not very abundant,” says Hopkinson. “But it’s important to bear in mind that we don’t really have anything to compare it to because we’ve never done this before. All we can do is take our estimates of snowpack water equivalents in the mountains and relate it to similar data structures such as precipitation gauges, snow pillows, field data or runoff records.” While the LiDAR results are comparable to traditional measurements, LiDAR can provide more spatially precise. #environment #lidar data.https://https://lnkd.in/gCBKgbBh
