In spatio-temporal applications, moving objects detect their locations via location-aware devices and update their locations continuously to the server. With the ubiquity and massive numbers of moving objects, many spatio-temporal access methods are developed to process user queries efficiently. Spatio-temporal access methods are classified into four categories: Indexing the past data, Indexing the current data, Indexing the future data, and Indexing data at all points of time. This short paper is Part 2 of the authors' previous paper. In Part 2, they give an overview and classification of spatio-temporal access methods that are published between the years 2003 and 2010.
