Unit1 What is Geomatics? 3页Data plotting (presentation) is handled through the use of mapping and other illustrative computer programs; the presentations are displayed on computer screens (where interactive editing can occur) and are output on paper from digital plotting devices. 数据绘图（描述，表达）是通过使用绘图和其他示范的计算机程序；这种表达显示在电脑屏幕（可以进行交互式编辑）和通过数字绘图设备输出到纸上。

Once the positions and attributes of geographic entities have been digitized and stored in computer memory, they are available for use by a wide variety of users. Through the use of modem information technology (IT), geomatics brings together professionals in the following disciplines: surveying, mapping, remote sensing, land registration, civil and marine engineering, forestry, agriculture, planning and development, geology, geographical sciences, infrastructure management, navigation, environmental and natural resources monitoring, and computer science.Other Definitions of Geomatics.一旦地理实体的位置和属性已被数字化并存储在计算机的内存中，它们即可以被各种各样的用户使用。

Surveying is the art of making such measurements of the relative positions of points on the surface of the earth that, on drawing them to scale, natural and artificial features may be exhibited in their correct horizontal or vertical relationships.测量是测定地面上各点的相对位置，以便根据它们之间正确的水平或竖直关系，按比例展示出天然地物和人工地物的一种技术。

一、名词解释：1、Surveying (测量学）is the art of making such measurements of the relative positions of points on the surface of Earth that,on drawing them to scale natural and artificial features may be exhibited in their correct horizontal or vertical relationships.2、Plane surveying （平面测量)is of wide scope and utility,and its methods are e mployed in the vast majorit y of surveys undertaken for various purposes,such as en gineering ,architectural,legal,c ommercial,scientific,geograph ical,exploratory,military,and n avigational.3、Geodetic surveys（大地测量）are usually of a nati onal character,occasionally w orks of international coopera tion,and they are undertaken as basis for the production of accurate maps of wide areas.4、Leveling（水准测量) is t he general term applied to a ny of the various processes by which elevations of point s or differences in elevation are determined.5、The theodolite （经纬仪）is an instrument designed for the measurement of hori zontal and vertical angles.It is the most precise instrume nt available for such observ ations,and is of wide applica bility in surveying.6、A traverse（导线）is a series of consecutive lines whose lengths and directions have been determined from field measurements7、Traversing(导线测量）,the act of establishing traverse stations and making the ne cessary measurements,is one of the most basic and wid ely practiced means of deter mining the relative locations of points.8、Azimuths（方位角）are measured clockwise from th e north end of the meridian through the angle points. 9、Topographic surveys（地形测量）are made to deter mine the configuration (relie f) of the earth’s surface and to locate natural and cultur al features on it.10、A topographic map（地形图）is a large scale repres entation of a portion of theEarth’s showing culture, relief, hydrography, and perhaps vegetation.11、Systematic-Error(系统误差）:These-errors conformto mathematical and physical laws.Their magnitude maybe constant or variable depending on conditions.12、Radom error(偶然误差）：These are errors that remain after mistakes and systematic errors have been eliminated.13、Precision(精度)refers to the degree of refinementor consistency of a group of measurements.14、Accuracy(准确度）which denotes the absolute nearness of measured quantities to their true values.二、填空1、The metal case is attached to some part of the instrument in such a way as topermit some (adjustment) of the position.2、Transits,are instrumentswhich ..... Along the verticalplane (altitude) as well asthe horizontal plane (azimuth).3、These instruments are (tripods),plane tables,(level rods),chains,and (tapes).4、As can be observed ,EDM systems are made up ofthree components-(a transmitter),(a reflector),and (a receiver).5、....the telescope must becapable of rotation about a(horizontal axis),for measurement of horizonal angles,the instrument must be rotatedabout a (vertical axis).6、There must be an (indexmark) on the rotating part,placed so that readings canbe taken against it on the(graduated circle).7、.....the observer operatesa setting device to obtain a(mean reading) free from(eccentricity error).8、If the (plumb bob) is not over the point,the (centering screw) can be loosenedand the.......9、These notes include directions.....stations with (fourdifferent positions).Two readings were taken on each position (one with the telescope normal or direct and onewith the instrument (reversed or plunged)).10、The line is determinedby a telescope with the usual components consisting of(object glass),(focusing arrangement),(diaphragm withcross-lines), and (eye-piece).11、A level fitted with (horizontal circle) and (stadia lines) can be used to make acomplete (three-dimensional) survey of a limited area round the instrument.12、Levels are used to obtain the direct measurement of （height differences）between two points.13、Which transmit either (modulated laser) or (infrared light) having wavelengths within or slightly beyondthe ......14、Which transmits (microwaves) with (frequencies) in the range of 3 to 35GHZcorresponding to wavelength of about 1.0 to 8.6 mm.15、The methods used in measuring angles or directionsof traverse lines vary,and include (compass bearings），（interior angles),(deflection angles),(angles to the right),(azimuths).16、The instrument is oriented at each station by (backsighting) on the previous point with （the back bearingset) on the plates.17、(Electronic devices) and (taping) are used most often and provide the highestorder of accuracy.18、On construction work,(allowable limits of closure)depend on the use and extent of the traverse and typeof project.Bright location, for example ,demands a highdegree of precision.19、Vertical control is provided by bench marks in or near the tract to be surveyed.It becomes the foundation for correctly portraying reliefon a map,A （vertical control net)is established by (lines of levels）starting fromand closing on bench marks.三、翻译：1、It is convenient to considerthat a bubble tube has anaxis,which may be taken as astraight line parallel to the freesurface of the liquid when thebubble is in the centralposition determined by thegraduation marks.当气泡处于分划线所确定的中心位置时，我们可以很容易想像水准管有一个轴，这个轴可以看作是一条与液体的自由表面平行的直线。

测绘工程专业英语1. Introduction测绘工程是一个涉及测量、制图和地理信息的专业领域。

作为全球定位系统（GPS）、激光雷达（LiDAR）等测绘技术的发展，测绘工程在土地测量、制图和地理信息系统（GIS）等方面发挥着关键作用。

在这个专业中，专业英语是非常重要的，它主要用于与国际同行交流、阅读英文文献、理解国外的测绘技术方法和标准等。

2. Basic Terms and Concepts2.1 Surveying测量是测绘工程中最基本的概念之一。

它涉及测量地球表面和地下物体的位置、形状和特征。

测量通常使用各种仪器和技术，如全站仪、经纬仪和水准仪。

测量的主要目的是精确定位地理要素，并为其他测绘工程任务（如制图和GIS）提供数据支持。

2.2 Mapping制图是将测量结果表现在图上的过程。

地图是以图形方式展示地理要素的平面。

制图可以使用计算机辅助设计（CAD）软件来完成，也可以使用手绘的方式制作。

制图需要掌握地理坐标系统、图投影、符号学等知识。

2.3 Geographic Information System (GIS)地理信息系统（GIS）是一种结合地图和数据库的技术，它可以用来存储、检索、分析和显示地理数据。

GIS在测绘工程中广泛应用，可以用于土地规划、资源管理、环境保护等方面。

在学习测绘工程专业英语时，了解和掌握与GIS相关的术语和概念非常重要。

3. Technical English in Surveying and Mapping3.1 Coordinate Systems坐标系统是测绘工程中常见的概念，用于确定和表示地理要素的位置。

常见的坐标系统包括经纬度坐标和平面坐标。

经纬度坐标使用纬度和经度来表示位置，而平面坐标使用XY坐标来表示位置。

在专业英语中，了解和使用这些坐标系统的术语是必要的。

3.2 Surveying Instruments测量仪器在测绘工程中起着至关重要的作用。

常见的测量仪器包括全站仪、经纬仪和水准仪等。
