| Section I: Core | |
| Temporal GIS | Novel research domain at large at the intersection of temporal systems and GIS and whose objective is to explicitly extend current GIS to dynamic real-world phenomena. |
| Spatio-temporal Modelling | Development of conceptual and logical models oriented to the representation of spatio-temporal information. |
| Temporal Modelling | Conceptual and logical approaches for the modelling and representation of time. |
| Spatio-temporal Analysis | Development of integrated analytical spatio-temporal frameworks for the analysis of spatio-temporal information. |
| Query Languages | Query languages applied to the manipulation of spatial and temporal properties, and relationships in space and time, and implemented by spatio-temporal and standard query languages. |
| Case Studies | Successful T-GIS stories that solve spatio-temporal problems in different domains, e.g., transport, naval, census, and environment. |
| Time Geography | Principles and foundations of Time Geography as defined by Hägerstrand and followers. Developing of the space-time cube. |
| Temporal Databases | Domain of research in the database domain oriented to the development of conceptual and logical temporal, spatio-temporal, and moving object databases. |
| Surveys and Reviews | Bibliographic compilations, annotated bibliographies, surveys, and reviews relating to temporal aspects in spatial, temporal, and spatiotemporal modelling and other spatial/temporal subjects. |
| Reports and Studies | Several research agendas, foundational documents, and report studies related to the origins of T-GIS and GIScience are declared and/or defined. |
| Section II: Secondary | |
| Moving Objects and LBS | Development of frameworks for the representation and manipulation of moving objects, services and applications derived from them. |
| Data Mining and Analysis | Data mining and analysis methods related to mining in spatio-temporal databases and for spatio-temporal knowledge discovering. |
| Databases & Spatial Databases | References related to the origins, development, and evolution of databases and spatial databases. |
| Spatial Data Modelling | Spatial data models and spatial data representation methods. |
| Spatial Data Structures | Spatial data structures, storage data models for spatial data, data structures in information systems, encoding in spatial databases. |
| Spatial Reasoning | Qualitative spatial reasoning. Qualitative abstractions of spatial aspects of common-sense knowledge that can be able to model dynamic geographic phenomena. |
| AI and Logic | Works coming from the Artificial Intelligence and Logic research fields which have contributed to model temporal aspects in information systems and spatial information systems. |
| Semantics and NLP | Semantic and linguistic aspects of geography in space, processing of temporal expressions through Natural Language Processing techniques, algorithms for processing of language, and general computational techniques to handle language in computer systems. |
| IR, GIR, and TIR | This section is quite related to the previous, but it is focused on Information Retrieval (IR), Geographic Information Retrieval (GIR), and Temporal Information Retrieval (TIR). |
| Annotating Time | Works dealing with Natural Language Processing applied to the identification and tagging of temporal expressions considering the semantic meaning and semantic relationships. |
| Ontologies | List of ontologies and ontology–based methodologies applied to spatial/temporal domains. Ontological foundations of temporal GIS. |
| Visualization | Graphical representations of geographic information regarding their properties and relationships in space and/or time considering both dynamic and static aspects. |
| Topology | Spatial and temporal topological relationships and properties. |

| GIS and GIScience | General background concepts of Geographic Information Systems and Science: theory and definitions, implementation, and development. |
| GI and data | Foundational topics regarding the perception, definition, and modelling of geographic information in digital systems. Evolution of cartography from ancient to contemporary methods. Background concepts such as Naive Geography, and other topics that have shaped geographic information and data. |
| Software | Software packages and libraries for databases, SDI, GIS, and T-GIS. Articles in which software prototypes and implementations are described are also included. |

| Section IV: Standardization | |
| Institutions | Online references and websites of the institutions that have made sort of contributions to T-GIS and cross-related topics, especially databases and GIS. |
| Standardization | Contributions to the development of methodologies for the implementation of (potential) standards. |
| W3C, ISO, OGC | These categories group several standards related to mark-up languages and/or the above-mentioned subjects. The listed standards are classified according to the three most relevant standardization institutions. |
