Lack of detailed data support in the early investment stage, and various types of data are complex and difficult to share;
There are numerous safety hazards during the construction process, and it is not possible to timely understand the real-time status of the site;
Using traditional instruments to measure earthwork volume has long measurement cycles, limited conditions, high time costs, and low productivity;
The traditional engineering progress adopts the form of reports and reports, and the data is not intuitive, accurate, and the reports are not truthful.

The drone collects data in the early stage, analyzes the excavation volume, calculates the engineering quantity information, and shares the data in a timely manner;
Drones conduct safety inspections of personnel and key areas and machinery from a high-altitude perspective;
Based on 3D point clouds or 3D models for measurement, it is realistic, objective, and reproducible, fitting more than a hundred times the number of terrain point clouds;
The progress of the project can be visually displayed through various forms such as panoramic images, orthophotos, 3D models, etc.
