Based on the object - oriented technique, this study defines four types of geographical event, i. e. expansivity, contraction, rebirth and vanishment events for management of land use data. and it further designed an object - superposition data updating model based on the land use feature of point, line and polygon ， which would take the advantage of the gis overlay function to effectly implement of updating spatial and attribute data
從面向對象的方法入手，定義了引起土地利用變化的擴展、收縮、新生與消亡四種地理事件，並分別按點狀地物、線狀地物和面狀圖斑的土地利用實體特徵設計了對象疊加更新模型，從而能利用gis強大的空間分析能力，來有效地實現空間數據和屬性數據的一致性更新。 -
A simple example is given to support the theory. object - oriented technique is widely used in gis data modeling. point - object class, line - object class, time class, polygon - object class and complex - object class are extracted from geo - objects, which combines with spatio - temporal topology forms an object - oriented gis spatio - temporal data model
運用面向對象的分析技術，對gis中點、線、面基本對象類和復雜對象類的分析與描述，結合時空拓撲的描述，總結出了一個面向對象的gis時空數據模型，體現了面向對象理論在gis時空數據建模中的思想。
