What is it about?
The amount of sources and sheer volumes of spatiotemporal data have met an unprecedented growth during the last decade. As a consequence, a rapidly increasing number of applications are seeking to generate value by crunching those data. The development of a system that will tap into the potential value of the spatiotemporal big data analysis for a multitude of applications remains one of the biggest challenges in computer engineering. This paper delves into the key-characteristics of the most prominent suchlike systems. In particular, it provides a thorough analysis of NoSQL datastores as well as a traditional relational database system in terms of their geospatial querying capabilities.

Why is it important?
The goal of this paper is to highlight these spatio-temporal functionalities of DBMSs and present the key architectural characteristics that are supporting them. It goes on to perform a comparison between a relational database system and several widely used NoSQL datastores across those characteristics. Based on the litera- ture review and to the best of our knowledge the most prominent differences concerning geospatial support for these data stores, are their data model and a number of geospatial capabilities. Such capabilities relate to geospatial indexing used, the geometry types supported and the spatial query operators performed.
