1. Flight record: There will be detailed flight records during the aerial survey and mapping of unmanned aerial vehicles, recording flight time, position, altitude, speed and other information. These records can be used as evidence to prove that the UAV has indeed carried out aerial survey and mapping tasks.

2. Image data: The main achievement of UAV aerial survey and mapping is image data. These image data can be processed and analyzed by different technical means, so as to extract geographic information and make maps. These images can be used as evidence to prove that UAV aerial survey and mapping have produced corresponding results.

3. Data processing flow: UAV aerial survey and mapping needs to process image data, including data correction, registration, stitching and other steps. The data processing process needs scientific methods and technical means, and detailed records and documents are needed for review and verification. These records and documents can be used as evidence to prove the credibility of UAV aerial survey and mapping results.

4. Professional report: UAV aerial survey and mapping results usually need to be compiled according to customer needs. These reports should include the purpose, methods and achievements of aerial surveying and mapping, as well as the corresponding data processing process and technical specifications. The report can be used as evidence to prove the legitimacy and credibility of UAV aerial survey and mapping results.

In a word, the reliability and authenticity of UAV aerial survey results can be proved by flight records, image data, data processing process and professional reports. Of course, in practical application, it is necessary to follow relevant laws, regulations and industry norms to ensure the legitimacy and accuracy of UAV aerial survey and mapping results.
