Hello dear friends!Today, Mr. Xinji would like to talk to you about a very interesting topic: What are the directions for the postgraduate examination of surveying and mapping?I believe that many friends will be a little confused when choosing the direction of postgraduate entrance examination, it doesn't matter, let's take a look with Mr. Xinji!
1.GeodesyThis direction mainly studies the shape, size, gravitational field and its changes over time. Through the measurement of the earth's surface, we can better understand the structure and movement of the earth, which is of great significance for the study of climate change.
2.Surveying EngineeringThis direction mainly involves surveying problems in engineering construction, such as engineering surveying, photogrammetry and remote sensing. In modern engineering construction, accurate measurement is the key link to ensure the quality and safety of the project.
1.CartographyThis direction mainly studies the production, design, analysis and application of maps. Through the study of maps, we can better understand how geospatial information is expressed and transmitted, providing accurate geographic information for various applications.
2.Geographic Information SystemsThis direction mainly involves the design, development and application of geographic information systems. Geographic information system is a computer system that can store, manage, analyze and display geographic information, and is widely used in urban planning, resource management, environmental protection and other fields.
1.PhotogrammetryThis direction focuses on methods and techniques for measuring ground targets using photographic techniques. Through the processing and analysis of aerial photography, satellite remote sensing and other data, we can obtain accurate three-dimensional information of ground targets and provide data support for various applications.
2.Remote sensingThis direction mainly involves the observation and study of the Earth's surface using remote sensing technology. Remote sensing technology can obtain various information on the earth's surface, such as surface temperature, vegetation cover, and water distribution, through satellites, aircraft and other platforms, which is of great significance for resource investigation and environmental monitoring.
Marine surveying and mapping is an important branch of surveying and mapping, which mainly studies the acquisition, processing, analysis and application of marine geospatial information. Through the study of seabed topography, seabed resources, and marine environment, we can better understand the structure and movement of the ocean, and provide technical support for the development of marine resources and marine disaster early warning.
Smart city is a hot field that has emerged in recent years, mainly studying how to use information technology to promote the intelligent development of cities. In this field, spatiotemporal big data is an important research direction, mainly studying how to collect, process and analyze various spatiotemporal data in cities, and provide support for urban planning, traffic management and other fields.
The above are the five main directions of the graduate school entrance examination of surveying and mapping majors introduced by Mr. Xinji. Of course, with the progress of science and technology and the development of society, the research field of surveying and mapping is also expanding and deepening. In the future, we can expect more new technologies and methods to be applied to the surveying and mapping discipline to provide us with more and more accurate geospatial information.
