One type of query refers solely to the absolute or relative locational properties of the spatial entities.

Other queries may relate to specific attributes of the spatial entities, or to combinations of these attributes, to the exclusion of any locational property.

The first is cartographic and defines the relative or absolute location of spatial entities (points, lines and polygons) in the area of interest.

The second kind of data consists of the attributes or properties of the spatial entities shown on the maps.

A geologic province is a spatial entity with common geologic attributes.

Similarly, the shape can influence interaction and flow among spatial entities (Arlinghaus and Nystuen 1990; Ferguson and Kanaroglou 1998; Griffith 1982).

There are no spatial and temporal entities in the ontology, only spatial and temporal relations on thick objects.

Many data sets, such as spatial entities of countries or common structures for governments, can be organized into natural hierarchies.

Complex adaptive systems theory as applied to spatial analysis suggests that simple interactions among proximal entities can lead to intricate, persistent and functional spatial entities at aggregate levels.

Hence, communities are spatial entities although they are not ultimately defined by topographical features.
