Due to the increase in a necessity, operability, and data availability, spatio-temporal analysis has been gathering popularity. However, there are few studies focusing on systematic reviews of it. This paper first shows basic concepts for spatio-temporal analysis such as geometrical representation of entities and changeability of attribute values over time. Then the paper constructs a matrix showing the characteristics of earlier studies. The matrix consists of two stages, where the first stage concerns the temporal representation and types of the entities, and the second stage concerns spatial representation, changeability of location, shapes and attribute values. The matrix helps us to understand the characteristics of the studies and uniqueness or similarity when compared to others.
