Data comprised of x-y coordinate representations of locations on the earth that take the form of single points, strings of points (lines or arcs), or closed lines (polygons).

Data that is based on a structure which stores and represents map features by a set of ordered "x,y" coordinates. This differs from the raster data structure in which attributes are attached to individual grid cells or pixels. (See Raster data).

When used in the context of spatial information, refers to a format where all data is stored as points, lines, and areas rather than as an image or continuous tone picture

an array of data with one dimension (i.e., a list of values).

A coordinate-based data structure commonly used to represent map features. Each linear feature is represented as a list of ordered x,y coordinates. Attributes are associated with the feature (as opposed to a raster data structure, which associates attributes with a grid cell). Traditional vector data structures include double-digitized polygons and arc-node models.

Positional data in the form of coordinates of the ends of line segments, points, text position, etc

One method of storing, representing or displaying spatial data in digital form. It consists of using coordinate pairs (x,y) to represent locations on the earth. Features can take the form of single points, lines, arcs or closed lines (polygons) (see Raster Data).

a data structure used to represent linear geographic features. Feature are made of ordered lists of x,y coordinates and represented by points, lines, or polygons; points connect to become lines, and lines connect to become polygons. Attributes are associated with each feature.

One of the three types of spatial data in a GIS (the others being image and raster data). Vector data represents geographic objects as points, lines or polygons.

GIS data structure for using point, line, and polygon features to represent objects on the ground.

A form of digital data comprising x, y coordinate representations that are portrayed by points, lines (strings of points), or polygons (closed lines).

Data represented in the form of mathematical equations.
