Vector geodata consists of sequentially ordered pairs of geographic (latitude, longitude) or projected (x,y) coordinate pairs.
A buffer zone is the area within a specified distance of a map feature. The shape of the buffer zone depends on the type of geodata or feature.
Geographic data interpolation provides information about topography between sampled data points.
Polygon objects allow standard set operations.
Eliminate visually redundant coordinates to remove unnecessary detail, and to speed and stylize map displays.
Geographic objects represented by vector data might or might not be formatted as polygons.
Calculate the intersections of vector data, circles, and rhumb lines.
A geographic data structure is a structure array with one element per geographic feature.
Vector data can represent entities of different dimensionality.
