Vector geodata consists of sequentially ordered pairs of geographic (latitude, longitude) or projected (x,y) coordinate pairs.
This example shows how to display vector data on a map, and how to print to screen the coordinates of points in the vector data.
A geographic data structure stores geographic features as elements in a structure array. The structure has fields such as the geometry of the vector feature, and the coordinates of points in the vector.
Vector data can specify the type of relationship between coordinates as isolated points, line segments, or enclosed areas.
Eliminate visually redundant coordinates to remove unnecessary detail, and to speed and stylize map displays.
Geographic data interpolation infers the value of geographic data at locations between sampled data points.
