| 向量 | vector One of the two major types of internal data organization used in GIS. Vector systems are based primarily on coordinate geometry and take advantage of the convenient division of spatial data into point, line, and polygon types. Vector structures are especially suited to storing definitions of spatial objects for which sharp boundaries exist or can be imposed (地理信息系统中用于内部数据组织的两种主要类型之一，向量系统主要基于坐标几何，并利用将空间数据划分成点、线和多边形类型的便利性。向量结构特别适合于存在尖锐边界的，或可被施加的空间对象的存储定义。) |
