Locational data. Usually refers to distribution of a variable or the relationships between variables in a geographic region. Demographic features, marketing distributions, energy resource data and topographic data are examples of information readily represented spatially, that is, on a map.
One of the two main types of data in a GIS (the other being attribute data). Spatial data represents the shape, location or appearance of geographic objects. It can be in vector, raster or image format.
also known as geospatial data or geographic information. Refers to information that identifies the geographic location of natural or constructed features and boundaries on the earth, including the oceans. This information is available to University students, faculty and staff either via the GIS office in the Library, or, for some software, via a public or home computer via the GIS website.
One of the three kinds of data (spatial, textural and image). Spatial data is categorized according to the following feature types: Zero-dimensional features: Primitive Points; topological Node. One-dimensional features: Primitive Lines, Strings (multiple nonbranching lines), arcs (mathematically defined curve; topological Links, chains, and rings. Two-dimensional features: Polygons defining enclosed areas, Pixels, and Grid Cells.
Spatial data is data that describes the attributes of some object or thing occurring at one or more locations or in a region in geographic space. Spatial data is made by connecting data about a theme with a spatial model of its geographic distribution. See the Guide's Spatial data page.

Each layer will have a value for its parameter, e.g. Brookston silt loam, that will vary from location to location. Thus, the soils data layer is composed of soil types (names or values) for each point within the region for which the GIS database is applicable.
