Simulation technology of punctual geo - objects based on 技術的點狀地物仿真技術研究
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?qū)ο蟮姆治黾夹g,對gis中點、線、面基本對象類和復雜對象類的分析與描述,結(jié)合時空拓撲的描述,總結(jié)出了一個面向?qū)ο蟮膅is時空數(shù)據(jù)模型,體現(xiàn)了面向?qū)ο罄碚撛趃is時空數(shù)據(jù)建模中的思想。
