First of all, we need to understand the concept of surveying and mapping aerial photography. What is surveying and mapping aerial photography?
Surveying and mapping aerial photography concept: Surveying and mapping aerial photography refers to aerial photography of the earth's surface from the air by installing aerial cameras on aircraft (aircraft, helicopters, airships, balloons, etc.), with the purpose of obtaining aerial images with a certain degree of overlap within a specified range.
Secondly, we need to know clearly what kind of business the company can engage in and what are the restrictions on the scope of work after handling the qualification of surveying and mapping aviation photography?
Business type of surveying and mapping aerial photography: General aerial photography, UAV aerial photography, tilt aerial photography. At present, many UAV patrol and line patrol businesses, air ground integration solutions, and smart series businesses are basically involved in aerial survey.
Limitation of work scope : Generally, it starts from Grade B, and Grade B shall not contract projects within two or more provincial administrative regions. If you have obtained Grade B qualification for 2 years, with a single performance exceeding 50w and professional performance exceeding 600w, you can apply for Grade A. Grade A is generally approved by the provincial department.
After we know what surveying and mapping aerial photography is, we need to know the specific details of this qualification.
First, we should make clear the basic conditions of the company:
（1） Having legal personality;
Interpretation: If a branch company has an independent legal person business license or a legal person certificate of a public institution, it can apply. If the branch company has an independent legal person, it cannot be responsible for human affairs. It is difficult to approve when it comes to foreign investment, so it needs to find other ways.
（2） Having surveying and mapping professional and technical personnel and surveying and mapping related professional and technical personnel suitable for surveying and mapping activities;
Interpretation: 1. Handling surveying and mapping aerial photography requires 15 technicians, 1 senior professional title of surveying and mapping, 2 intermediate professional title of surveying and mapping/registered surveyor, 3 junior professional title of surveying and mapping, and 9 surveying and mapping related professionals. The supporting materials for the authenticity of professional titles are key.
2. Surveying and mapping specialty refers to geodesy, engineering surveying, photogrammetry, remote sensing, cartography, geographic information, cadastral surveying and mapping, surveying and mapping engineering, mine surveying, marine surveying and mapping, navigation engineering, land management, geographical condition monitoring and other specialties.
3. Surveying and mapping related majors refer to geography, geology, engineering survey, resource survey, civil engineering, architecture, planning, municipal administration, water conservancy, power, road and bridge, industrial and civil construction, ocean, computer, software, electronics, information, communication, Internet of Things, statistics, ecology, printing, artificial intelligence, big data, cloud computing, confidentiality, archives and other majors. (It is enough to have the graduation certificate available on the corresponding Xuexin website)
4. The high-level surveying and mapping professional technicians can offset the low-level surveying and mapping professional technicians, and the surveying and mapping professional technicians can offset the surveying and mapping related professional technicians.
5. Technicians need to pay social security for more than 3 months, and technicians outside the province need to provide payroll records. At present, most regions are strict, and we can minimize the risk of personnel introduction based on experience.
（3） Having technical equipment and facilities suitable for surveying and mapping activities;
Interpretation: 1. Class B of surveying and mapping aerial photography requires a total of 2 unmanned aerial survey acquisition systems, professional surveying and mapping aerial cameras and other surveying and mapping sensors;
2. Unmanned flight measurement and acquisition system: at least equipped with flight platform and aerial camera sensor (including camera, airborne laser scanner, airborne SAR);
3. Professional mapping aerial camera and other mapping sensors: including aerial camera, airborne laser scanner, airborne gravimeter, airborne SAR;
（4） It has a sound technology and quality assurance system, security guarantee measures, information security and confidentiality management system, and mapping results and data archives management system.
Interpretation:
1. Class B requires at least one technician to obtain the qualification certificate of geographic information security training, which can be operated in the whole process;
2. The archives shall meet the requirements of "three irons, one machine and eight prevention";
3. It is better to have security software;
4. Preparation of other system documents.
