翻译如下内容：
GIS是以解算空间/地理坐标为主要目的计算机系统.它建立于数据的基础上,数据是GIS的灵魂.数据分为矢量数据和栅格数据.矢量数据和栅格数据组成了GIS的数据模型.通过数据模型和先进的计算机技术我们可以绘制各种地图的主要要素、符号等,还能够模拟出地形——也可以说是虚拟现实技术.GIS应用于很多方面,比如地图制图、环境保护、城市规划、通信、交通等很多方面.它最主要的运用是空间分析,空间分析能够解决很多问题.它的目标是提供一个空间框架——在这个体系中,我们可以对地球资源的合理化运用以及人类环境的可持续发展管理进行决策支持.
GIS最重要的是数据,它来源于原有的地图数据数字化、遥感图像、测量数据、数字资料和文字报告.获取的数据经过分析、筛选等处理后,就能放进数据库.值得一提的是,GIS的数据有数据质量指标,这个指标有微观方面和宏观方面,微观方面它是指定位精度、属性精度、逻辑一致性和分辨率的差别,宏观方面是指数据的完整性、时间性、地域性.

GIS based on the solution space/geographic coordinates for the main purpose computer system. It was founded in based on the data of data is the soul of GIS. Data into vector data and raster data. Vector data and raster data formed GIS data model. Through the data model and advanced computer technology we can draw many maps of main elements, symbols, and also can simulate the terrain, also can saying is the virtual reality technology. GIS application in many aspects, such as mapping, environmental protection, urban planning, communication, transportation etc many aspects. It's main use is the spatial analysis, spatial analysis can solve a lot of problems. Its aim is to provide a space framework -- in this system, we can use the rationalization of the earth's resources and the sustainable development of human environment management decision support.
GIS is the most important data, it comes from the original map data digitization, remote sensing image, measurement data and digital material and written report. Data obtained through analysis, screening, after processing can be put in the database. What is worth mentioning, GIS data have data quality index, the index has micro and macro aspect, micro aspect it is to appoint a precision, attribute precision, logical consistency and resolution differences, macroscopic aspect is the integrity, timeliness, according to index, regional.
