Vector Data
Analyze and transform point, line, and polygon data
Vector data uses points, lines, polygons, and their non-spatial attributes to describe real-world objects, locations, and events. For example, you can represent a city by using a point, a river by using a line, and a country by using a polygon. The vertices of points, lines, and polygons can be in geographic (latitude-longitude) or projected (x-y) coordinates.

Vector Data Representations
- 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.
Modify and Analyze Vector Data
- 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.
- 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. - Vector Intersections
Calculate the intersections of vector data, circles, and rhumb lines.
