【正文】 dam in the world of maintenance, and some projects together, are put in the first place. In fact, the vast majority of the destruction of the dam, don39。s Barcelona arch dam after the crash, the deformation of dam observation work more attention, since the international conference to dam deformation observation of dam as an important content included in the agenda, and published a large number of observation data. The meeting in many countries (Committee) or government, to monitor reservoir or dam safety and much stricter regulations. Four, surveying and mapping science classification Surveying and mapping science as a subject, can be divided into several independent discipline: 1, geodesy (geodesy): is the space in a certain time reference system, measurement and description of the earth and other plaary bodies of a discipline. Another definition is studied in larger regional or global 3D geodetic control work, gravity work, determination of the earth39。s gravity field and its variation theory, technology and method of the subject. The main contents are: triangulation, traverse survey, leveling, astronomical measurement, gravity measurement, satellite geodesy, very long baseline interferometry, inertial measurement, ellipsoidal geodesy, the earth shape theory and surveying adjustment etc.. [geodesy Knowledge Window] geodesy is one of the oldest Applied Earth Science, the classical definition is: measurement and description of the surface of the earth science. With the development of space geodesy theory and techniques (GPS, VLBI, SLR etc.), geodesy, break through the traditional limitations of time and space, enter the new stage of the development of modern geodesy, which is defined as: accurate determination of the threedimensional position, shape, size, the surface of the earth and its external gravity field, and monitoring and interpretation over time they change science. So geodesy from engineering application to fundamental earth science change, bee one of the frontier subjects to promote the development of earth sciences.

A large amount of information and Digital Earth are related to geographic information, these related with geographical information, must be based on the same reference frame, theory and method for setting up the frame of reference can only adopt the modern geodesy. Therefore. The modern geodesy is the support of the subject construction of Digital Earth spatial data framework. Thus, the modern geodesy in people39。s role in the play in the rich countries will be more and more. [geodesy Knowledge Window]. Bulletin of Surveying and mapping in 2021 eighth page twentyfirst. 2, photogrammetry and remote sensing (photogrammetry and remote sensing): geometric and physical information on the electromagic wave sensor acquisition target, shape, size, spatial location to determine the target, interpretation of its properties and relations, and a discipline graphics, image and digital form theory and technology. The subject was mainly used for topographic mapping. With the development of Surveying and mapping technology and remote sensing technology, photography and research objects bee more and more diverse, the theory of remote sensing camera today in many scientific fields. 3, engineering surveying (Engineering Surveying): Resea
