章节摘录

版权页:插图:The major task of geodesy is to determine the size, shape and gravity field of the Earth as well asto locate and map the objects near the Earth surface.Here the size, shape of the Earth, we mean the physical and the mathematical surface ofthe Earth. The physical surface of the Earth is the border between the solid or fluid masses andthe atmosphere. The irregular surface of the solid Earth is incapable of being represented by asimple mathematical model. Therefore, it is described point wise by the use of coordinates of thegeodetic control points. On the other hand, the ocean surface takes about 70% of the totalEarth's surface and an equipotential (level) surface of the Earth's gravity field that best fit themean sea level (MSL) in the ocean can be used to represent the figure of the Earth. This levelsurface is called geoid.A defined mathematic model of the Earth is required for the computations in geometricgeodesy. Because of its simple equation, a rotational ellipsoid flattened at the poles is bettersuited as a geodetic reference surface than the geoid. The optimal ellipsoid approximating thegeoid is called as mean Earth ellipsoid. Figure 1. 1 shows the relationship among the surfacesrelated to geodesy.The body of the Earth and its gravity field are subject to temporal variations of secular,periodic, and singular nature, which can occur globally, regionally, and locally. The geodeticmeasurements and evaluation techniques can detect these changes. Geodesy contributes to theinvestigation of the dynamics of the terrestrial body. The figure of the Earth and the externalgravity field are accordingly conceived as time dependent variables.The objectives of geodesy can be summarized as follows:(1) To determine the shape of the Earth and its external gravity field as well as theirchanges with time, to study the crust deformation, and to observe the polar motion andmonitoring the ocean surface.(2) To set up the geodetic coordinate system and to maintain the national horizontalgeodetic control network and the vertical leveling network.(3) To study the observation methods for geodetic instruments such as total stations, levels.
