Core The Core section includes the most relevant categories (areas) that have impacted the development of T-GIS. According to our classification, the references included in this section correspond to the fields which have made a sort of contribution either on a temporal or a spatio-temporal issue. Articles that survey, report or review this sort of contributions are also included here. According to our classification, the references included in this section compounds the core collection of published works in T-GIS.
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, environment.
Time Geography Principles and foundations of Time Geography as defined by Hägerstrand and followers.
Temporal Databases Domain of research in the database domain oriented to the development of conceptual and logical temporal, spatio-temporal and moving-objects databases.
Surveys and Reviews Bibliographic compilations, annotated bibliographies, surveys, and reviews relating to temporal aspects in spatial, temporal, and spatio-temporal 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.
Secondary The Secondary section includes the categories that, although not being a direct part of T-GIS, play a relevant role in its development in addition to strongly support spatio-temporal modelling. Key concepts such as the conceptual modelling of time (e.g. AI and Logic) or spatial data modelling and reasoning are considered particularly for the integration of the temporal variable in GIS.
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.
Spatial Databases References related to the origins and evolution of databases and the development of 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. Qualitative abstractions of spatial aspects of common-sense knowledge that can be able to model dynamic geographic phenomena.
Databases References related to the origins and evolution of databases and the development of spatial databases.
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 one below, but it is focused on Information Retrieval, Geographic Information Retrieval, and Temporal Information Retrieval.
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.
Spatial Data 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.
Spatial Statistics Theory related to the analysis of geographical phenomena considering statistics and other mathematical foundations, specially those focused on the characterization of the distribution of events throughout space.
Cartography This section is related to General and Thematic Cartography as well the fundamentals of visualization techniques for cartographic composition. Map projections are well documented from the mathematical point of view.
Others The Others section includes those research areas that, being considered as individual subjects, are not relevant enough to be directly related to the development of T-GIS.
Interoperability Interoperability of geoservices. Semantic and temporal interoperability. Types of interoperability.
SDI and Geoservices Trends on Spatial Data Infrastructures as for design and implementation. Development and implementation of geoservices.
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 concept 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.
Calendars Definition and formalization of calendars. Tools for comparing and convert dates from a calendar system to another.
3D/4D Three dimensional modelling and spatio-temporal analysis in 3D environments.
Standards The Standards section includes articles, institutions, norms, and standards that rule temporal and spatio-temporal aspects in GIS and cross-related areas. Mainly, standards from OGC, ISO, and W3C are referenced.
Standardization Contributions to the development of methodologies for the implementation of (potential) standards.
Institutions Online references and websites of the institutions that have made contributions to the research fields related to T-GIS, especially databases and GIS.
