What Are the Main Advantages of Aerial Photogrammetry Technology?

Jun 09, 2023

Aerial photogrammetry technology is a technology that applies flight technology to surveying and mapping. For surveying and mapping, the application of advanced technology can not only solve many problems in traditional surveying and mapping, but also make surveying and mapping technology play a greater value.

Advantage 1: wide application fields and large development space

Traditional topographic surveying techniques are easily affected by various factors such as technical level, personnel professional skills and terrain characteristics. For complex terrain, traditional topographic surveying techniques show more limitations. Aerial photogrammetry technology can effectively solve the difficulties encountered in artificial topographic survey and many existing problems. It has shown strong advantages in geological analysis of mining areas, environmental monitoring, and early warning of natural disasters. On the one hand, it can ensure the safety of personnel; on the other hand, the accuracy of measurement data can be greatly improved, especially in the early warning and prevention and control of natural energy disasters, accurate measurement data and precise positioning are crucial. Aerial photogrammetry can provide three-dimensional data information for engineering surveyors and mappers. By obtaining a large amount of large-scale topographical data information in the high altitude, it can provide scientific basis for the work in the fields of mine geological survey and environmental protection. It can scientifically evaluate the geology of mining areas and provide ideas for the prevention of natural disasters and mining accidents.

Advantage 2: The information content is complete and specific

In traditional surveying and mapping methods, the acquisition and recording of data information basically relies on manual work, but aerial photogrammetry technology can realize complete and accurate data processing and storage. While the high-altitude topographic data is quickly acquired, it has great performance in data acquisition and storage. More precise and efficient features. At the same time, the system can automatically establish a resource library of data resources, which can provide scientific and comprehensive data support for subsequent engineering surveying and mapping work. In the acquisition of human geographic information, aerial photogrammetry technology shows unique advantages, which can provide a more regional direction for environmental protection and ecological environment construction, and can make environmental governance work more targeted. The more specific the information content, the more accurate the direction will be provided for the formulation of environmental protection strategies, thereby improving the efficiency and value of environmental protection work.

Advantage 3: save costs and improve economic benefits

Surveying and mapping work has the problems of heavy workload and high cost investment. Due to the lack of high-tech applications in traditional surveying and mapping work, the work efficiency cannot meet the actual needs. For dangerous environments or complex terrain surveying and mapping, there is even no way to start. Influenced by various factors, due to technical limitations, it is impossible to obtain the required terrain information in many environments. The application of aerial photogrammetry technology can avoid many problems caused by human factors. For example: In terms of the accuracy of data measurement, human factors are likely to cause errors, but aerial photogrammetry technology can accurately measure terrain and landforms through advanced instruments, especially the unavoidable problems of human factors can be solved. Especially in the surveying and mapping of large-scale terrain, traditional surveying and mapping work has many limitations. The working mode of combining aircraft and photographic instruments can break through the limitations of technology, improve work efficiency, reduce unnecessary costs, and then more Funds are used for the development and research of surveying and mapping technologies.
