tatukgis 缓冲区分析 空间关系描述 TatukGIS supports a powerful, yet easy to manage, mechanism for querying against spatial relationships between two shapes. This mechanism is known as the Dimensionally Extended 9 Intersection Model (DE-9IM). The idea is to manage a 9 element mechanism in which each element defines the relationship possibilities between the interiors, exteriors, and boundaries of two shapes. The relationship is defined in terms of intersection types, or lack of an intersection.
