矢量数据
分析并转换点、线和多边形数据
矢量数据通过点、线、面及其非空间属性来描述现实世界中的对象、位置和事件。例如，您可以用点表示城市，用线表示河流，用多边形表示国家。点、线和多边形的顶点可采用地理坐标（纬度-经度）或投影坐标 (x-y) 表示。

向量数据表示法
- 创建地理空间表
地理空间表包含点、线和多边形数据的几何形状及属性。从向量数据文件导入地理空间表、将表转换为地理空间表，或从数组创建地理空间表。 - Geographic Data Structures
A geographic data structure stores geographic features as elements in a structure array. The structure has fields such as the geometry of the feature and the coordinates of points in the vector.
修改和分析矢量数据
- Combine Vector Data Using Table Joins
Link vector data in tables and geospatial tables according to shared attributes. - Create and Display Polygons
Display polygons using map or geographic coordinates. - Compare Polygons and Line Segments
Geographic objects represented by vector data might or might not be formatted as polygons. - Simplify Vector Coordinate Data
Eliminate visually redundant coordinates to remove unnecessary detail, and to speed and stylize map displays. - Geographic Interpolation of Vectors
Geographic data interpolation infers the value of geographic data at locations between sampled data points. - Find Vector Intersection Points
Calculate the intersection points of lines, polygons, and circles that are represented by coordinate arrays.
