How to write your understanding of this major?
Fan Wen: I came to the Yellow River Water Institute and chose surveying and mapping as my major. I was really confused at first, because it is said that surveying and mapping is very hard. When the school didn't start, at home, I also checked some surveying and mapping evaluations. It's really a good major, but it's a bit bitter.

"Surveying and mapping work, there is no beauty of flight attendants, no beauty of chefs, no smell of fresh fat, all it has is endless pace and excessive use of computers." This is an online evaluation, of course, a bit one-sided. Now I have a comprehensive understanding of my major.

Through the classroom of college students' professional quality development, I have a deeper understanding of my major. Through the teacher's introduction, I know that the main research object of surveying and mapping is the earth and its surface morphology, and it is divided into geodesy, general surveying, photogrammetry, engineering surveying, marine surveying and mapping, cartography and other sub-disciplines in the development process. Engineering investigation usually refers to various investigation theories, methods and technologies adopted in the investigation, design, construction and management stages of engineering construction. The courses of engineering survey technology specialty in our college mainly include topographic survey, cadastral survey, control survey, engineering survey and GPS survey. The instruments we use are: level, theodolite, total station, gyroscope, GPS and so on. The training mode of our school is 2+ 1+2+ 1, which means that we have to go out for internship every two semesters. This is more conducive to the improvement of our practical ability. The teacher also said that surveying and mapping is a career to serve the society. There is a saying: social construction, mapping first. The employment rate of surveying and mapping major in Yellow River Water Institute is very high, not only because of the large demand of surveying and mapping industry, but also because of the policy of cultivating me in the school. The school pays attention to practice, reaching almost as many hours as practice and classroom teaching. Employment enterprises need professionals with strong practical ability, and schools should set up a good education model according to local conditions. Our major has a wide range of employment directions, such as mining, water conservancy and hydropower, transportation, civil engineering, urban construction and engineering survey in agriculture and forestry. Employment orientation: Surveying and mapping, water conservancy and hydropower, geology and mineral resources, transportation, town planning, municipal construction, real estate, land and resources utilization and other departments are engaged in surveying and mapping of various projects.

It's been more than three months since school started, and we have also experienced two weeks of internship. During my study and internship, I also got a practical understanding of my major.

Since we have chosen surveying and mapping, we should establish correct learning values. Don't think that I am only a freshman now, and I still have a few years to study. In fact, we can understand what the teacher said in class if we want to teach ourselves, but in order to form a complete knowledge network, we can accurately grasp the important and difficult points.

If you want to have the will not to be tired, you must grasp the "preparation" link, which is like the foundation of a house. If the foundation is not firm, there will be endless troubles. Every time you have an outdoor class, you should be fully prepared. Every step of the whole experiment and its precautions should be familiar with.

We should cultivate our earnest and meticulous style of study. For example, the calculation of closed loop and loop table is a link, and there are many graphs. It also involves the constellation problem, so we should not only have correct thinking, but also be patient, careful and enthusiastic, which is also the way of life we should have in our daily life.

Strong sense of team, everyone is a whole, we should trust each other and help each other, and try our best to complete the task efficiently in a short time. At the same time, the team members have also improved their understanding, which is also a good opportunity for students to communicate with each other. I was also very pleased with this during my internship. Due to my negligence, I got the data wrong all afternoon. I felt guilty and blamed myself all the time, but all the people in our group came to comfort me. I'm terribly sorry.

For some problems that you can't solve, ask the teacher modestly and don't go ahead blindly. An experiment is a continuous process, and one carelessness may lose the game.

Surveyors should have a strict professional attitude, so as to be good surveyors. Surveying and mapping is tiring, but since you have chosen it, you should study hard.

It is not difficult to travel across mountains and rivers, but if we idle around in times of hardship, the surveying and mapping industry we are engaged in will haunt us too much. But in any case, since I chose this line and my father-in-law Lu, I should look at all this optimistically and positively.

Cognition is cognitive knowledge, that is, the human brain reflects the characteristics and connections of objective things and reveals the meaning and function of things to people. Generalized cognition includes all human cognitive activities, that is, perception, memory, thinking, imagination, language understanding and production. Cognition is an information processing process, which can be divided into a series of stages, such as receiving, coding, storing, extracting and using stimuli. In a narrow sense, cognition is sometimes equated with memory or thinking.
