What is surveying and mapping?

Question 1: What is the significance of surveying and mapping? To put it simply, it is the process of drawing the actual things (topography, landforms, relative geographical position and things used) on the drawings according to a certain proportion through instruments and other equipment. On the contrary, it is a process of moving drawings into actual reality according to their contents. This process is surveying and mapping. Commonly used surveying and mapping instruments are theodolite (measuring angle, orientation, etc. ) level (commonly used for measuring elevation and leveling ground) and total station (the most commonly used instrument in highway construction) have wide precision and application range.

Question 2: What is surveying and mapping? Refers to measuring and collecting the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. Includes two main contents: measurement and drawing. Surveying and mapping is widely used in economic construction and national defense construction. In urban and rural construction planning, land resources utilization, environmental protection and other work, it is necessary to conduct land survey and map various maps for planning management. In geological exploration, mineral development and water conservancy and traffic construction, geological survey, control survey of various building design and construction, mine survey, route survey and topographic map must be carried out. Marching operations need military maps, as well as accurate geocentric coordinates and gravity field data to ensure that long-range weapons can accurately hit targets.

Question 3: What is the purpose of surveying and mapping? Surveying and mapping refers to the activities of measuring, collecting and expressing the shape, size, spatial position and attributes of natural geographical elements or surface artificial facilities, and processing and providing the obtained data, information and achievements. At the same time, it is based on computer technology, photoelectric technology, network communication technology, space science and information science, with global positioning system (GPS), remote sensing (RS) and geographic information system (GIS) as the technical core, and measures the existing feature points and boundaries on the ground to obtain graphics and sub-information reflecting the current situation on the ground, which can be used for planning, design and administrative management of engineering construction.

Question 4: What exactly does the surveying and mapping project do? What you do depends on where you will work in the future. When you go to the city survey institute, it is basically the basic topographic map of the city and the completion inspection line of the real estate. Go to the Pipeline Bureau to do pipeline survey and calibration, go to the Geographic Information Center to do surveying and mapping or GIS development, go to the Provincial Bureau of Surveying and Mapping to do small and medium-scale topographic surveying and mapping, and road construction is just some road lofting and the like.

Question 5: What does surveying and mapping do? Surveying and mapping is measuring and drawing. To put it bluntly, it is to fix the points on other people's drawings on the ground (for example, someone's design unit actually built a building, and you give them a field survey of the foundation), or draw the points on the ground on the map by measuring coordinates (that's how the map came from). Use special software to draw pictures, not by hand.

1. Joining a company specializing in surveying and mapping services, such as a surveying and mapping team, will definitely provide coolies at the beginning;

2. Enter the surveying and mapping departments such as real estate;

3. Surveying and Mapping Institute, of course, it also has something to do with it ~ ~ Now it seems that only graduate students or above can enter, and colleges and universities are fierce and very popular.

4. Surveying and mapping instrument companies, doing technology or sales;

5. Surveying and mapping software development, programming and the like, this is also used for postgraduate study, and GPS navigation in the car belongs to surveying and mapping development software. Wow, take mine, I knocked so much ~ ~ ~ hey hey.

Question 6: What does the surveying and mapping project do? Topic introduction:

-Measuring all kinds of information of space and the earth and drawing topographic maps of all kinds of information.

Taking the shape, size and gravity field of the earth and other planets as the research object, the research and mapping objects are very extensive, mainly including various surface features, landforms and underground geological structures, hydrology, mineral deposits and so on. Such as mountains, rivers, houses, roads, vegetation and so on. Usually, before developing a virgin land or carrying out large-scale engineering construction, topographic maps must be measured and drawn by surveying and mapping engineers, and other information can be provided before decision-making, planning and design, so surveying and mapping is very important. Usually, the maps and traffic maps we see are completed on the basis of surveying and mapping. Engaged in surveying and mapping work often carries out field work, and should be psychologically prepared to face the tough environment.

Lecture content:

-Need a solid foundation knowledge

Surveying and mapping engineering needs good basic knowledge of mathematics and computer, mainly including matrix theory, numerical analysis, functional analysis, computer software foundation, geodetic foundation, as well as more in-depth computer graphics, geographic information system principles and so on. The main professional courses are computer software foundation, space geodesy, modern survey data processing theory, advanced survey application and geophysics. In the learning process, theory and practice are closely combined, and internships are often carried out. For example, you will be asked to draw a campus map and a certain scale topographic map in your freshman year. Graduation practice may help a place to establish a geographic information system, which is very important and popular at present.

Work after graduation:

-Work related to surveying and mapping engineering.

Surveying and mapping engineering management and supervision engineer-engaged in surveying and mapping engineering technical design engineering, starting salary 1500 ~ 3000 yuan/month. ?

Senior talents engaged in various aspects of scientific research and engineering-planning, design, construction and operation management, starting salary is 2000 ~ 4000 yuan/month.

List of related majors:

◆ Surveying and mapping engineering requires a strong sense of responsibility and patience, and you are also required to be very careful. A lot of drawings may make you feel a little boring, but field work can let you travel around great rivers and mountains and find the feeling of traveling. I hope you are good at using modern tools and finish the task easily.
