What is non-spatial data in GIS?
Non-spatial data (also called attribute or characteristic data) is that information which is independent of all geometric considerations. For example, a person’s height, mass, and age are non-spatial data because they are independent of the person’s location.
What is the name of the non-spatial data that accompanies spatial data in GIS?
Spatial data are usually accompanied by non-spatial data, known as attribute, stored in tabular format. The appended attribute data provides additional information about each geographic feature and its characteristic.

Non-spatial data may be joined to geocoded files with matching attributes and displayed as regular maps. This is common in Geographic Information Systems (GIS). For example census information such as race or income, non-inherently spatial data, can be displayed as maps.
How is non-spatial data handled by GIS?
