Unit1

今天,地理信息系统可以定义为创建,存储,处理,可视化和分析的地理信息的计算应用程序的能力。它发现在资源管理,公共事业管理,电信,城市和区域规划,车辆调度与包裹递送,并在所有的处理与地球表面的科学的最强烈的应用。

Geographic information systems in recent decades has been used as a basic tool integrated into the planning and management of urban and resources, such as: land use planning, utilities management, ecosystem modeling, land evaluation, transportation planning, market analysis, real estate analysis and other applications .

Unit2

每个地理数据集的特点是它描绘的特性。其代表的形状和位置的方法,各种地理操作的实用程序。每个模型都有自己的优点和局限性,并支持其他数据类型的操作可能不会。

Property sheet including the rows and columns. Each row is a record of the description of the data, column to record details of the attribute values, such as area, soil type, graphic symbols, etc. In the same location may in each row in the table could be the same value.

Unit5

首先,我们需要表现出更多的令人信服的,现有的空间分析技术可以用来解决感兴趣的重要的实质性问题在GIS从业者,这种技术能够提供有意义的见解不能获得其他。

Browse and read the map data is relatively simple, usually can be done by moving the mouse or use the control menu and icon. For example, the original view shows the map data range, but by clicking on the magnifying glass icon or inward arrow icon or use the drop-down menu to choose can be enlarged view.

Unit6 地理信息系统和空间分析有着不断变化的关系多年来,随着计算的重点已从加工到公众的沟通,并在GIS软件演化的影响。GIS提供的空间分析的推广一套前所未有的机遇,并准备进入复杂的庞大的用户社区的例程。

Geo computation contains a large amount of computational intensive scientific paradigm, this paradigm includes three interrelated aspects: one: geographical data; two: in order to provide modern computing technology, computing solutions for those with geographic information question three: high-end computing hardware.

Unit7

究其原因,空间统计分析软件连接到一个GIS是第一,由于地理信息系统作为一个通用平台,用于管理空间数据和第二的重要性,因为地理信息系统有许多都需要的空间数据分析设备,以重新发明他们似乎浪费。地理信息系统是有价值的空间统计分析软件包发展的总体能力是它的数据库管理能力;的区位和拓扑信息,其持有约到哪些属性是附加的面积单位或点;其制图显示功能。

Brings more advantages based on the seamless integration of Arc / Info and mapping of SAGE data analysis packages and special modules. A prominent advantage is the various components of the system (database, graphics and cartography window displays) connected together, such as property values in the database, including data analysis can be generated in the process do not need to convert data files and display or draw.

Unit8 在互联网使用地理信息系统的一个决定性的问题是数据(矢量或光栅)的,用于将数据传送到客户端的形式。在原则上,可以使用栅格以及矢量数据。应该提到的是,传送格式是独立于数据被存储在服务器上。在大多数应用中的地理数据存储为矢量数据的形式在一个专有的格式结构化对象。

All major GIS companies realize the possibility of using GIS on the Internet, and thus provides a web mapping products. End-users no longer need to deal with the complexity of geographic data and GIS system purchase. Existing products is the first step in the development of Internet GIS. The future potential of the Internet will be used to develop a higher level, flexible, interactive GIS applications....

Unit9

选址是查找位置或功能上规定的条件或标准的一般过程。出于各种目的,它通常表示为现场适用性,场地不适合,或站点的敏感性分析。现场适用性是找到最合适的位置或场所针对特定用途的过程。

Looking to meet certain conditions of the location or the elements of the process are many GIS operations and general purpose applications. Whether the final analysis is a suitable means or simply choose a location which is substantially the same.

Unit10

分布式地理信息系统正在成为一个重要的组成部分。一个基本的版本是呈现在网页上地理信息系统的工作,无论是显示器的成品地图和图形,或使用简单的互动功能,如选择的主题和展示数据的表。互动式地理信息系统正在成为一个显著的业务。分布式GIS也可能意味着GIS软件,数据,或经营分布,例如,使用数据从其他几个网站在一个地方一个服务器上运行,并发送产品到位于其他地方的第三方客户软件。

Revolution in computer-related technology information age is indeed the most obvious and exciting performance. Technology trends are fascinating and promising investment in this area will also be useful and interesting.
