地理信息系统（GIS）可以定义为用于输入、存储、操作、分析和显示地理或空间数据的系统。这些数据由点、线和多边形（图1）沿着连同它们的关联属性（即，点、线和多边形表示的特征的特性）。例如，这些点可以表示危险废物场地位置;与每个场地相关联的属性可以是倾倒在该场地的特定化学品、所有者以及该场地最后一次使用的日期。线可以表示道路、溪流或其他线性特征，而多边形可以表示诸如植被类型或土地使用的区域特征。
A geographic information system (GIS) can be defined as a system for entering, storing, manipulating, analyzing, and displaying geographic or spatial data. These data are represented by points, lines, and polygons (fig. 1) along with their associated attributes (i.e., characteristics of the features that the points, lines, and polygons represent). For example, the points may represent hazardous waste site locations; the attributes associated with each site may be the specific chemical dumped at the site, the owner, and the date the site was last used. Lines may represent roads, streams, or other linear features, while polygons may represent areal features uch as vegetation types or land use.
