9、determining elevations, such as balancing backsight and foresight distance in differential leveling, automatically takes into account the curvature of the earth and compensates for earth curvature and refraction, and elevations referred to the curved surface of reference are secured without extra ef

10、fort by the surveyor.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 i

11、s 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

12、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。在大地测量中，测站之间距离长，需要使用比平面测量中更精密的仪器和测量方法。4. Distance between two points can be horizontal, slope, or vertical. 两点之间距离可以是水平的，倾斜的或垂直的。orizontal and slope distances can be measured with lots of techniques of measurement depending on the desired quality of the

13、result. 水平距离和倾斜距离测量有多种方法，取决于测量的精度要求。5. The advent of EDM instrument has completely revolutionized all surveying procedures, resulting in a change of emphasis and techniques. Distance can now be measured easily, quickly and with great accuracy, regardless of terrain conditions.电子测距仪的问世给测量程序带来一场深刻的革命，

14、导致了重点与技术的改变。不管地形情况如何，距离测量现在都变得简单、迅速，而且有很高的精度。5. More complete EDM instruments also have the capacity of measuring horizontal and vertical or zenith angles as well as the slope distance. These instruments referred to as total station instruments.更集成的电子测距仪除测量斜距外，同时还具备测量水平角、竖直角和天顶距的功能。这类仪器一般称之为全站仪。6. C
