| 摘 要： | 空间物体描述是ＧＩＳ的基本任务之一，而空间物体的分类是空间物体描述的基础。理想的空间物体分类模型不但应具有完备描述（构造）各种空间物体的能力，而且应能够揭示基本的空间关系，有助于空间分析的规范化系统化。本文在分析空间概念模型和现有的几种空间物体分类模型的基础上，提出了空间物体分类的基本原则，给出了新的空间物体分类模型：简单点、复合点、简单线、有向简单线、复合线、有向复合线、多边形，并说明了以这类基本物体类型构造复杂物体的一般性方法。

| Abstract: | Spatial object representation is a b&sic problem of GIS,and it is based on SPatialobject classification. A good classification model is not only good for decribing(constructing) spatial objectS, but also gab for revealing spoilal relations, and helpful fornormalizing and systematizing sP8tial analysis methods. In this paper, after analyzing somespatial concept models and spatial object classification models, we proposed basic principlesfor classification along with a new spatial object classification model,in this model, we define seven basic spatial objectS, namely, simple point, complex point, simple line, directedsimple line, complex line,directed complex line and polygon,we alSo explained how to construct complex spatial objects with these basic objects. |
