What are some coordinate systems commonly used in surveying? 6, the meridian, the first meridian, meridian plane, the first meridian surface concept 7, relative to Gao Cheng and absolute Gao Cheng 8. What is the basic principle of measurement work? 9, what are the three elements of measurement? 10, the use of horizontal surface instead of the level surface should pay attention to what? Two, refer to the answer 1, there are several major classifications of surveying. What are the main tasks of all kinds? Answer: according to the object of study, adopt the difference of technical means and application, the measurement credits are the following Discipline: (1) geodesy: the science of studying the shape and size of the earth, the earths gravity field, and the theory, techniques and methods of establishing a national geodetic network over the broad earth. It is the theoretical foundation of the whole surveying. (2) general surveying: the study of theories, techniques, and methods of Surveying and mapping in smaller areas of the earths surface. (3) photogrammetry: the study of the theory, techniques, and methods of determining the shape, size, nature, and spatial location of objects by means of photography or remote sensing. (4) Engineering Surveying: the study of the theory, techniques and methods of Surveying in engineering survey, design, construction, completion acceptance and operation management. (5) Oceanography: the science of the theory, techniques and methods of surveying the earths surface waters (rivers, lakes and seas), ports, waterways, and underwater landforms. (6) Cartography: theory, technology and method based on the measurement results of the scientific production of map. 2, what are the main tasks of civil engineering surveying
