An extension of SQL is formalized for the management of spatio-temporal data, i.e. of spatial data that evolves with respect to time. The syntax and semantics of the extension is fully consistent with SQL. The formalism is very general, in that the extension can be applied to any kind of data, either temporal or spatial or conventional.

Spatio-Temporal Data Model and Spatio-Temporal Databases
2010Spatio-temporal database can deal with the objects’ temporal and spatial properties uniformly, and it can manage data that is evolving with time, i.e., the information of spatial objects whose shape and position evolve with time. In spatio-temporal database, spatial data has one more time dimension, which increases the complexity of data management. In

Spatio-temporal queries in HBase
2015 IEEE International Conference on Big Data (Big Data), 2015Geoscience gives insights into our surroundings and benefits many aspects of our life. Nowadays, with massive sensors deployed to sense all kinds of parameters for environments, tens of billions, even trillions of sensed data are collected and need to be analyzed for surveillance or other purposes.

Spatio-Temporal Reasoning Based Spatio-Temporal Information Management Middleware
2004There are too may spatial or spatio-temporal applications, so the integrating ability became more and more important. OpenGIS technology can only solve the syntax integrating, not the semantic one. Moreover, uncertainty and multiple granularity are intractable problems.

Spatio-temporal vernier acuity
Spatial Vision, 1998The study of space-time vernier (STV) provides information on the spatio-temporal structure of the visual system in the same way that the classical spatio-spatial vernier (SSV) provides information on its spatial structure. The transposition of a SSV task into a STV one yields the following experimental format: an object (in the present case a Gaussian

An automated edge detection algorithm, referred to as spatio-temporal edge focusing, is presented. It combines spatial edge focusing and temporal edge focusing. While spatial edge focusing and temporal edge focusing each have their own advantages and disadvantages, it is shown that the combination of these two techniques maintains their advantages ...

Both the temporal and spatial dimensions add substantial complexity to data mining tasks. First of all, the spatial relations, both metric (such as distance) and non-metric (such as topology, direction, shape, etc.) and the temporal relations (such as before and after) are information bearing and therefore need to be considered in the data mining ...
