Enhancing Safety and Accuracy<\/h2>\n

What is a UAS-based geohazard assessment?<\/h3>\n

A UAS-based geohazard assessment refers to the use of Unmanned Aerial Systems (UAS), commonly known as drones, to collect data and assess potential geological hazards. This assessment involves utilizing UAS equipment to capture photographs, create 3D models, and collect lidar data in areas that are difficult to access or heavily vegetated. By using UAS technology, geotechnical engineers and construction professionals are able to obtain accurate and high-quality measurements, which are essential for analyzing the causes of slope failures and designing effective mitigation solutions. Additionally, the data collected from UAS platforms can be utilized for tasks such as creating landslide inventories, monitoring changes in slope conditions, and modeling geohazard susceptibility. This information can then be used in risk assessment and asset management programs, enabling data-driven decision-making and promoting safer and more efficient construction practices.<\/p>\n

How are UAS-based geohazard assessments conducted?<\/h2>\n

UAS-based geohazard assessments are conducted using specialized UAS equipment and techniques. Here is an overview of the process:<\/p>\n <\/div>\n

\n
\n

Step 1<\/h4> <\/i>\n

Data Collection<\/h3>

UAS equipment, such as drones, is used to collect aerial photographs and lidar data in heavily vegetated areas. These data sources are essential for creating accurate 3D models of the slope and surrounding terrain.<\/p> <\/div>\n

\n

Step 2<\/h4> <\/i>\n

Structure-from-Motion (SfM) Point Cloud Models<\/h3>

The collected photographs are processed using Structure-from-Motion (SfM) techniques to generate detailed point cloud models. These models provide a high level of accuracy and help in identifying potential geohazards.<\/p> <\/div>\n

\n

Step 3<\/h4> <\/i>\n

Geohazard Investigation<\/h3>

The point cloud models are analyzed by geotechnical engineers to identify slope failures, landslide inventories, and changes in slope conditions. This investigation helps in understanding the root causes of geohazards and designing effective mitigation solutions.<\/p> <\/div>\n
