🚀 Difference between Single & Multi Beam 🚀 🔻 hydrographic surveyors use sonars to remotely measure water depths. Sonars, installed on a boat or ship, use sound waves to determine the distance to the bottom, while laser scanners and lidar use light to determine distance from the instrument to the ground. 🔽 Single beam 🔷A single beam system measures the depth of water in a very small area, or basically a single point, directly under the sonar. 🔷 Single beams are often used in very shallow water or where complete bottom coverage is not necessary, such as widely spaced river cross sections. 🔽 Multi beam 🔷 Multibeam systems take hundreds of measurements in a swath or fan shape on the bottom. As the vessel moves forward, a wide stripe (much wider than the vessel) data is collected. 🔷 Multibeam systems are often used in deeper water or for projects that require complete coverage. 🔷 Multibeam systems are paired with an inertial navigation system that use two GPS/GNSS antennas and a highly sensitive motion sensor to model the movement of the boat or ship in the water. 🔷 The acquired multibeam and motion/positioning data is then processed to create bathymetric maps that show the features of the seafloor. 🔶 If anyone Have more Information and Can Share it with us leave it in Comments #survey #multybeam #MBES #Hydrography #surveyboat #watersurvey #Echosounder #AhmedSameh #dredging #Dredgger #APEX #marine #Naval #vessel

*Conducting a Topographic Survey*. What is a Topographic Survey or Topo Survey?. This is the Survey that involves detail picking of anything ( feature or phenomenal) that exists on the ground. These feature can be Roads, Houses, trees, hills( ant-hills) etc. A topo survey helps to understand the activities taking place on the ground, the terrain structure and others. Topo Survey can be conducted using machinery such as ; 1. Drones ( very fast method) 2. Global Navigation Satellite Systems( moderate method) 3. Total station.( slow method). ~The Geo Engineer~ ~ The Land Surveyor ~

Best Practices for GCPs (Ground Control Points) in Mine Surveying 👷🏻 1. Establish a robust network of GCPs. 2. Regularly monitor and maintain GCPs. 3. Use precise survey methods (e.g., GPS, total stations). 4. Integrate GCPs with other survey data (e.g., aerial photogrammetry, LiDAR). By implementing and maintaining an effective GCP network, mine surveyors can ensure accurate, reliable, and efficient data collection, supporting informed decision-making and safe operations. #mining #survey #team

#Drought #LiDAR #Alberta #BowRiver #OldmanRiver #UniversityOfLethbridge #TeledyneOptech #GalaxyLiDAR #AriesAviation #ULethbridge #TitanMultispectralLiDAR "... 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

Ground control points (GCPs) are crucial in surveying as they provide a reference framework for accurate data collection and mapping. GCPs are physical markers or identifiable features on the ground that are precisely located and measured, serving as a link between the surveyed data and the real-world coordinates. By establishing a network of GCPs, surveyors can ensure that data collected from various sources, such as GPS, photogrammetry, or LiDAR, is accurately georeferenced and aligned with the existing spatial framework. This enables the creation of precise maps, models, and analysis, which is essential for various applications like infrastructure development, urban planning, natural resource management, and disaster response. In essence, GCPs form the foundation for reliable and accurate spatial data, making them indispensable in modern surveying practices. #mining #survey #gcps #lidar
