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
- Create Geospatial Tables
Geospatial tables contain shapes and attributes for point, line, and polygon data. Import geospatial tables from vector data files, convert tables to geospatial tables, or create geospatial tables from arrays. - 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.
