Current hot projects
Three rights: land contractual management right, homestead ownership and use right.
Two rights and use rights: time and competent department.
The director is from the Bureau of Land and Resources, and the time is these two years, so I am not dead! The accuracy is mainly controlled within one meter! The accuracy of Sandian should be within one meter, so the rural areas in Yunnan are mostly in mountainous areas, which means that we can't fly too low. So is it difficult to achieve accuracy in aerial survey? In some places, it's almost ok. In fact, flying 800 can meet the requirements.
Office process:
Distortion correction-rotation-automatic matching-manual matching-aerial triangulation (aerial triangulation) and plotting: 1, orthophoto map; 2. Three-dimensional mapping method: drawing lines (topographic maps, contour lines))
Accuracy and flying height of aerial photogrammetry
1: 500 (0.05m) 350-500m， 1: 1000(0. 1m)600-800m， 1: 2000m (0.2m) 65438。

Aerial survey project cost standard
1:500 1: 1000 1:2000 1:5000
The project price is 53,000-40,000, 20,000-30,000, 0.8- 1 0,000.
Estimation of cost difference between aerial survey and manual survey
Due to the height difference, complexity, weather and other reasons, the cost of surveying and mapping areas varies greatly, but there are also relevant reference standards. Jinying UAV takes representative projects in Yunnan as an example;
The suburb is about 50 meters square kilometers, with mountains, farmland and some buildings.
It takes about 40 days to measure *20 people, and it takes about 200 days to change to 5 people. Daily salary and travel per person 150 yuan =120,000 yuan.
About 20 days *4 people * Salary and travel expenses per person per day 150 yuan = 12000 yuan.
Conclusion:
1, the cost of manpower survey is one tenth of that of aerial survey, which is about 10%. The cost of manual survey is about 10 times that of aerial survey.
2. During the construction period, if the number of people is the same, the aerial survey is one tenth of the manpower survey. In practical engineering, the investment of human survey is five times that of aerial survey, and the construction period is twice that of aerial survey.
3. Personnel, aerial survey and indoor staff are one tenth of those surveyed. For example, four people can complete twice as much work as about 20 people. In this way, it is easy for the company to maintain the stability of competent personnel and the technology is not easy to leak.
4. High precision and quality. Due to the great human factors in the accuracy of drawings in the project, only serious and responsible personnel can satisfy Party A, and the part made by careless and erratic people can easily lead to the ruin of the whole project, resulting in rework and even the loss of subsequent projects. Aerial survey can be completed by a few elite personnel, especially in the projects of 1: 2000 and 1: 1000, the quality control can be higher than manual survey, reaching or exceeding the standard, so as to do the current project well and obtain the follow-up projects.
5. Enterprise development and benefits. Due to the low cost of aerial survey and short construction period, enterprises can rapidly expand their business volume and benefit by 5-20 times, and even get larger projects, which can make enterprises quickly develop into industry leaders and get rich returns.
To sum up, the most important value of aerial survey is to save time, have orthophoto images and achieve accuracy.
Accuracy guarantee of aerial survey
1. Accuracy is easier to reach the standard. People in some places can't go, or their quality or sense of responsibility is not good. The aerial survey covered the whole area without any omission.
2. Aerial survey can also make orthophoto map of the whole area. Man-made survey can only draw lines.
Problems of aerial survey
Ultra-high income has preconditions: that is, it requires upfront investment, the courage and courage of entrepreneurs, and the support of professional aviation.
1. Initial investment: 300,000 *2 UAVs = 600,000, ground station and training: 200,000, about 800,000 * *. Enterprise preparation.
2. Flight risk: Because Yunnan is located in the mountainous area, the airflow is complex, and the flight and runway conditions are bad, the probability of falling off the plane is higher than that in the plain area, and each fall will generally cause thousands or tens of thousands of yuan of losses. Jinying UAV supports reducing this loss of enterprises.
3. Aerial photography qualification: surveying and mapping enterprises and institutions with good conditions and scale. Guidance and assistance of jinying unmanned aerial vehicle.
4. Air Force Air Traffic Control: Jinying UAV is a model UAV coach and air traffic control policy propagandist. Jinying UAV can voluntarily go through the formalities of air traffic control declaration.
5. Flight technical experience: Jinying UAV is a leading provider and service provider of aerial survey equipment in China, and its rich experience and superb technology ensure the completion of the flight.
Aerial survey advantages of jinying UAV;
1, mature aerial photography experience and indoor experience, many aerial surveys in the province and at home, and successful aerial surveys in Africa.
2. The leader of the remote control flying hand, installation and maintenance is the eagle, and the winner of the silver medal in the National Model UAV Competition.
3. Build a strong base for model airplane drones, train long-range flying hands and test drones.
4. Qualification of aerial photography of Provincial Bureau of Surveying and Mapping.
5. Policy propagandist of Air Force Air Traffic Control Committee and air traffic control applicant.

Conditions and procedures for applying for aerial photography qualification
Surveying and mapping enterprises and institutions with Grade A and Grade B qualifications have the conditions to declare. Jinying UAV can guide or assist in declaration.
Unqualified enterprises can fly through qualified enterprises or institutions, and Jinying UAV can provide support.
Air traffic control conditions
As long as the flight does not affect the existing routes such as civil aviation and flies over the military secret unit area, the air force air traffic control will approve the declaration of Jinying UAV.

What photogrammetry software are there in the domestic market?
This question is difficult to answer, and all the answers are difficult.
First: Virzoto, which was developed by Wuhan University, is now 60-70% reusable in the market.
Second: DPGrid, also developed by Wuhan University.
Third: pixel factory, a famous pixel factory, comes from France. As for who developed it, I'm not sure. It seems to have something to do with sports satellite company. This set is worth10 million yuan. There seem to be more than a dozen Golden Eagle UAVs in China.
Fourth: INPHO, this is also foreign. There are not many countries in our country. This seems to be made by Ackerman's team. Not really. After all, it is foreign.
Fifth: Hlava, this is American. The system was put forward by Hlava, and now the US military is using it again. This person once proposed the nuclear line, which is a great bull. It seems that there are several sets of this software in railway and electric power in our country, but it is also a very old version.
Sixth: The Chinese Academy of Sciences also proposed a system, but I really don't remember it. sorry
What does surveying and mapping industry mean?
To put it bluntly, the field of surveying and mapping is to collect field data, and the field includes data processing and graphic generation.
The software you want to use should be CASS, which is a drawing software based on CAD. If you don't know that you can learn related majors, then learn CAD first, and then CASS.
First of all, I suggest you learn the process of drawing. It will be much easier to learn specific things according to theoretical knowledge. If you have the conditions to go out and practice, you will make rapid progress.
If you study hard, you can get a picture in a month and a half at most.
If you want to know more about surveying and mapping, I suggest you refer to related books.
