Geographic data and related tabular data can be collected in-house or purchased from a commercial data provider.<br /> * &#039;&#039;&#039;人员&#039;&#039;&#039; (People): GIS technology is of limited value without the people who manage the system and develop plans for applying it.<br /> * &#039;&#039;&#039;方法&#039;&#039;&#039; (Methods): A successful GIS operates according to a well-designed plan and business rules.<br /> <br /> == 数据模型 ==<br /> GIS 主要使用两种数据模型来表达现实世界：<br /> * &#039;&#039;&#039;[[矢量数据模型]]&#039;&#039;&#039;：使用点、线、面来表示离散的地物，如建筑物、道路、行政区。<br /> * &#039;&#039;&#039;[[栅格数据模型]]&#039;&#039;&#039;：使用像元（Pixel）组成的网格来表示连续分布的现象，如高程、温度、降雨量。<br /> <br /> == [[空间分析]] ==<br /> [[空间分析]]是GIS的核心，它利用地理位置来进行分析。常见的空间分析功能包括：<br /> * &#039;&#039;&#039;缓冲区分析&#039;&#039;&#039; (Buffer Analysis)<br /> * &#039;&#039;&#039;叠加分析&#039;&#039;&#039; (Overlay Analysis)<br /> * &#039;&#039;&#039;网络分析&#039;&#039;&#039; (Network Analysis)<br /> * &#039;&#039;&#039;空间插值&#039;&#039;&#039; (Spatial Interpolation)<br /> <br /> == 主要应用 ==<br /> * &#039;&#039;&#039;城市与区域规划&#039;&#039;&#039;<br /> * &#039;&#039;&#039;环境影响评价&#039;&#039;&#039;<br /> * &#039;&#039;&#039;应急响应与管理&#039;&#039;&#039;（如疫情一张图）<br /> * &#039;&#039;&#039;商业选址分析&#039;&#039;&#039;<br /> * &#039;&#039;&#039;自然资源管理&#039;&#039;&#039;<br /> <br /> == 参见 ==<br /> * [[空间数据基础设施 (SDI)]]<br /> * [[开放地理空间信息联盟 (OGC)]]<br /> * [[WebGIS]]<br /> <br /> [[Category:地理信息系统]][[Category:地理信息系统]]<br /> [[Category:测绘学]]</div> WikiBot
