The process of utilizing Lidar technology for survey work involves several steps, from data collection to the finalization of drawings and maps. The following is an overview of the process that a survey team typically goes through when using Lidar technology.
- Data Collection: The first step in the process is to collect data using a Lidar sensor. The sensor emits laser beams towards the ground, and measures the time it takes for the laser pulse to bounce back. This distance information is used to create a point cloud, which is a 3D representation of the earth’s surface. The survey team will typically collect data on a large area, in order to gather a comprehensive view of the area.
- Data Processing: Once the data has been collected, it is then processed using specialized software. The software is used to clean and filter the data, which helps to remove any noise or errors. The software also allows the survey team to classify the data into different categories, such as vegetation, buildings, and ground.
- 3D Modeling: The next step is to create a 3D model of the area. The survey team uses the point cloud data to create a 3D representation of the earth’s surface. This model can be used for a variety of purposes, such as planning and design, and can be viewed from any angle.
- Map Creation: Once the 3D model is created, the survey team can then create maps from the data. These maps can be used for a variety of purposes, such as infrastructure planning, environmental studies, and land management. The maps can be created in a variety of formats, such as 2D and 3D, and can be tailored to the specific needs of the project.
- Quality Control: After the maps and drawings are created, the survey team will perform a quality control check to ensure that the data is accurate and meets the project’s specifications. This includes checking for any errors or inconsistencies in the data and making any necessary adjustments.
- Finalization: Once the quality control check is complete, the survey team will finalize the maps and drawings. These final products can then be used by the construction survey companies, municipalities, or other organizations for their specific projects.
In summary, the process of utilizing Lidar technology for survey work involves several steps, from data collection to the finalization of drawings and maps. The survey team uses specialized software to process the data and create a 3D model of the earth’s surface. This model is then used to create maps and drawings that can be used for a variety of purposes. The survey team performs a quality control check to ensure that the data is accurate, and then finalize the maps and drawings, which can be used for their specific projects.
