1、地理信息专业英语复习资料翻译： 1、GIS is a system of hardware，software aad procedures to facilitate the manipulation，analysis，modeling，representation and display of georeferencedcomplex problems regarding planning and management of resollrces， 翻译：gis是一个由硬件、软件和程序组成的系统，便于管理、处理、分析、模拟、表现并显示地理参照数据，从而解决规划和资源管理的复杂问题。 2、GI
2、S technology，integrates common database operations such as query and statistical analysis with the unique visualization and geographical analysis benefits offered by mapsThese abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterpri
3、ses for explaining events，predicting outcomes，and planning strategies(ESRI) 翻译：地理信息系统技术将诸如查询和统计分析的常见的数据库操作和地图特有的可视化功能和地理分析优势集成起来。这些功能是区分地理信息系统和其他信息系统的关键，并且对于众多的公共和私营企业用于事件解析，结果预测和战略规划十分有价值(ESEI)。 3、Projection is a fundamental component of mapmakingA projection is a mathematical means of transferring
4、 information from the earths threedimensional，curved surface to a twodimensional medium-paper or a computer screenMathematically speaking，map projectionsare transformations of geographic coordinates(1atitude，longitude)into the Cartesian(x，y)coordinate space of the map 翻译：投影是地图制作的一个基本要素，同时也是将信息从地球的三维
5、曲面上传递到纸张或电脑屏幕二维介质上的一种数学手段。从数学上来讲，地图投影就是将地理坐标(纬度，经度)转换为地图的笛卡儿空间坐标(x，Y)。 4、A raster based system displays，locates，and stores graphical data by using a matrix orgTid of cells such as squares，triangular，or hexagonal cells，or even irregular triangles orpolygons，which are tessellated to form geographical
6、representations 翻译：基于栅格数据的系统采用栅格单元有正方形、三角形或六角形形成了地理表征。栅格矩阵或栅格单元显示、定位存储地理数据，这些，甚至不规则三角形或多边形，这些单元嵌合在一起形成了地理表征。 5、A vector based system displays graphical data as points，lines or curves，or areas withattributes Cartesian coordinates (ie x and Y) and computational algorithms of thecoordinates define poin
7、ts in a vector systemLines or arcs are a series of ordered pointsAreasor polygons are also stored as ordered lists of points，but by making the beginning and endpoints the same node the shape is closed and defined 翻译：基于矢量数据的系统用点、线或曲线、面及其属性显示图形数据。笛卡儿坐标(即光和Y)和坐标计算算法确定矢量系统中的点、线或弧段是一系列有序点。面或多边形也是用一系列有序点储
8、存的，但是起始节点和结束节点相同以闭合和确定图形。 6、Geo-referencing describes the process of locating an entity in“real world” coordinates，establishing a relation between raster or vector images to map projections or coordinate systems 翻译：空间参照描述了定位实体在“真实世界”的坐标及确立栅格或矢量影像与地图投影或坐标系统关系的过程。 7、Map projections are systematic tran
