1、Geomatics is a relatively new scientific term created by Pollock and Wright in 1969,with the intention of combining the terms geodesy and geoinformatics.It includes the tools and techniques used in Surveying and Mapping, RemoteSensing(RS), Cartography, GeographicInformationSystems (GIS),GlobalNaviga

10、al tasks of the field work oftaking measurements and the office work of computing and drawing.Surveying is required not only for conventional construction engineering projects,mapping, and property surveys, but is also used increasingly by other physicalsciences, such as geology, geophysics, biology
11、, agriculture, forestry, hydrology,oceanography and geography, etc.随着现代数据采集和处理系统的发展 ,测量员的职责已经大大超出了传统的野外测量工作和内业计算和绘图工作。测量不仅适用于传统的建筑工程项目、 地图学和土地权属调查,也越来越多的适用于其他物理科学,如地质、地球物理、生态学、农学、林业学、水文、海洋、地理等。The essential work of surveying is to determine accurately the position of thefeatures on the surface of th
12、e Earth (horizontal surveying), and the elevations of thefeatures (vertical surveying), or a combination of both.Although different surveys are for different purposes, the basic operations include:measurements (fieldwork), computations and mapping (office work).From another point, the work of survey
13、ing is either to determine the locations(three-dimensional coordinates) of ground features and drawing all kinds of maps, orto mark out the designed buildings or structures in maps at their proposed positions.测量的基本工作是确定地球上物体的准确位置 (水平测量)和高度(垂直测量),或两者的结合。虽然不同的调查是为了不同的目的,基本操作包括:测量(野外),计算和绘图(内业)。从另一个角度,
14、测量的工作是确定地球表现上物体的位置(三维坐标)和绘制各种地图,或在地图上的建筑物、构筑物中标定他们的位置。Surveying operations include:(1) design of surveying procedures and selection of equipments;(2) acquisition and storage of data in the fields;(3) reduction or analysis of data in the office or in the filed;(4)preparation of maps or other displays

16、 of these tasks requires a familiarity with the uses of surveyingequipments and techniques, knowledge of fundamentals of the surveying process, andknowledge of various means by which data can be prepared for presentation.Definitions of control surveying and detail surveying:(1) Control surveying is
17、referred to the measurements of control points, which arewell spaced in the form of network and play controlling roles in survey area.(2) Detail surveying is referred to the work of measuring the terrain features aroundeach control point.这些任务的完成需要熟练使用测量设备和技术 ,测量过程的基础知识和在地图上展绘数据的各种知识。控制测量和碎部测量的定义:(1)

21、detic surveying is referred to the measurement and representation of the Earthsshape and size, gravity field and geodynamic phenomena (such as polar motion, Earthtides and crustal motion), and establishment of control networks of large areas forother surveys.调查有很多不同的分支,如大地测量、平面测量,工程测量,地形测量、 地籍测量、矿山测
22、量学等。1、大地测量学大地测量是测量和表征地球的形状和大小,重力场和地球动力学的现象(如极移、地球潮汐和地壳运动),建立用于其他大面积测量的控制网络的学科。In geodetic surveying, large areas of t he Earths surface are involved and the trueshape of the Earth must be taken into account, and the stations are normally longdistances apart, and more precise instruments and surveyin
23、g methods are required forthis type of surveying.In geodetic surveying, the shape of the Earth is thought of as a spheroid, although itis not really a spheroid in a technical sense.在大地测量学中, 由于地球外表的大部分地区都有涉及,所以地球的真实形状必须考虑进去,由于站点之间的分隔距离较远 ,所以需要更精密的仪器和测量方法。在大地测量学中,地球的形状被认为是一个球体,虽然在理论意义上并不是一个球体。Therefor
