在进行高程测量的一般程序中，比如水准测量中保持前后视距相等，自动考虑和补偿了地球曲率和大气折光的影响，基于曲面得到的高程仍然是可靠的，不需要测量员对数据进行进一步的处理。
3. The type of surveying that takes that takes into account the true shape of the earth is called geodetic surveying. This type of survey of survey is suited for large areas and long lines and is used to find the precise location of basic points needed for establishing control for other surveys. In geodetic surveying ，the stations are normally long distances apart, and more precise instruments and surveying methods are required for this type of surveying than for plane surveying.
这种类型的测量考虑到地球曲率的影响，被称为大地测量。
这种类型的测量的特点是区域广、基线长，用来测定控制点的精确位置。

7. The method of surveying called triangulation is based on the trigonometric proposition that if one side and three angles of a triangle are known, the remaining sides can be computed by the law of sines.
这种测量方法称为三角测量，是基于如下三角形定理：如果三角形的一条边长和三个内角已知，那么其余的边长可以根据正弦定理计算得到。
Furthermore, if the direction of one side is known, the direction of the remaining sides can be determined. And the coordinates of unknown points can be computed by application of trigonometry.
此外，如果其中一条边的方向已知，其余边的方向就可以确定。故未知点的坐标可以由三角公式计算得到。

There are many different types of surveys such as land surveys, route surveys, city surveys, construction surveys, hydrographic surveys, etc., but generally speaking, surveying is divided into two major categories: geodetic and plane surveying.

五、××题（每小题×分，共×分）
1. A total station is the most commonly used instrument now in geomatics engineering, which is fully integrated instrument that captures all the spatial data necessary for a 3-dimensional positional information. A total station integrates the functions of an electronic theodolite for measuring angles, an EDM for measuring distances, digital data and a data recorder. All total stations have similar constructional features regardless of their age or level of technology, and all perform basically the same function.
全站仪是当前测绘工程中最常用的仪器，它是一种高度集成的仪器，可以采集三维定位所需要的全部空间数据。
全站仪集成了电子经纬仪的测角功能，电子测距仪的测距功能以及数据采集和记录装置。不管生产的年代和采用的技术如何，所有的全站仪具有类似的结构，基本上实现了相同的功能。After the instrument has been set up on a control station, centered, leveled and properly oriented, and the prism target has been set up over another point whose position is to be measured, the surveyor may focus the target and depress a button. Then output from the horizontal and vertical circular encoders and from the EDM can be displayed at the instrument and stored in a data collector and enters into a built-in microprocessor. The microprocessor can convert the measured slope distance to the horizontal distance using the measured vertical or zenith angle. The microprocessor also computes the difference in elevation between the instrument center and the prism target. If the elevation of the instrument center (the HI) and the height of the reflector target (the HT) above the ground are entered, the microprocessor computes the elevation of the target station taking into account the effect of curvature and refraction.
当仪器安置在控制点上，对中，整平，正确定向，棱镜安置在待测点上后，测量员就可以瞄准目标，按下测量按钮。
这时水平度盘、竖直度盘以及距离测量的结果可以在仪器上显示出来，并且存贮到数据采集器和内置的微处理器当中。
利用垂直角或者天顶距，微处理器可以把测量的斜距转化为平距。
微处理器也计算出仪器中心和目标棱镜之间的高程差异。
如果输入仪器高和目标反射镜高，微处理器将会计算出目标站点的高程，并且考虑了地球曲率和大气折光的影响。
2. In the last decade, there has been dramatic development and growth in the use of hardware and software solutions to both measure and process geo-spatial data. This has created and will continue to create new areas of application, with associated job opportunities for suitably qualified graduates. As a result, the role of the “surveyor” is expanding beyond traditional areas of practice, as described above, into new areas of opportunity. In addition, recent advances in the technology of data collection and processing have blurred the boundaries of practice and activity between what were previously regarded as related but separate areas. Such developments are forecast to continue and will create new career paths for graduates whose education and training is broadly based and of a high academic standard.
在过去十年中，用于获取（测量）与处理空间数据的硬件和软件得到了巨大的发展。
这已经创造并将继续创造新的应用领域，以及与之相关的就业机会。
这已经创造并将继续创造新的应用领域，并为合适的毕业生提供了相关的就业机会。
这也使测量员突破了上述的传统测量领域，不断从事新的应用。
此外，数据采集和处理技术的最新进展，使得原本不同的相关领域的界限变得模糊。
预计这些发展将继续为教育和培训基础广泛，学术优异的毕业生创造新的职业途径。
As we know, surveying is divided into two major categories: geodetic surveying and plane surveying. Geodetic surveying takes into account the true shape of the earth whereas plane surveying treats the earth as a flat surface. The subject of this text aims at the study of the size
and shape of the earth which refers to Geodesy. The expression “the size and shape of the earth” has various meanings in geodesy according to the way it is used and the precision with which the earth’s size and shape is to be defined. The actual topographic surface is most apparent with its variety of landforms and water areas. This is, in fact, the surface on which actual earth measurements are made. It is not suitable, however, for exact mathematical computations because the formulas which would be required to take the irregularities into account would necessitate a prohibitive amount of computations.
众所周知，测量被分为两大主要类别：大地测量和平面测量。
大地测量考虑了地球的真实形状，而平面测量把地球表面当做平面。
本文的主题旨在探讨大地测量中相关地球的形状与大小。
短语“地球的形状与大小”根据其使用的方式和被定义的精度，在大地测量中有各种不同的含义。
真实地表最显著的特征是有各种各样的地貌和水域。
实际上，大地测量就是在这样的表面上进行的。
然而，它并不适合精确的数学计算，因为考虑这些不规则因素的公式需要大量的计算。
