A spatiotemporal database embodies spatial, temporal, and spatiotemporal database concepts, and captures spatial and temporal aspects of data and deals with: Geometry changing over time and/or Location of objects moving over invariant geometry (known variously as moving objects databases [ 1 ] or real-time locating systems ).
Unlike the OGC Web Feature Service (WFS), which returns discrete geospatial features, a WCS returns coverages—representations of space/time-varying phenomena mapping a spatio-temporal domain to a (possibly multidimensional) range of properties. As such, WCS focuses on coverages as a specialized class of features and defines streamlined ...
Initiative 10: Spatio-Temporal Reasoning in GIS, led by Max Egenhofer and Reginald Golledge Initiative 12: Integration of Remote Sensing and GIS, led by John Estes, Frank Davis and Jeffrey Star [ 7 ] In 1992 the list of publications resulting from these research initiatives and other efforts of the NCGIA were published in the International ...
The Modified Temporal Unit Problem (MTUP) is a source of statistical bias that occurs in time series and spatial analysis when using temporal data that has been aggregated into temporal units. [ 7 ] [ 8 ] In such cases, choosing a temporal unit (e.g., days, months, years) can affect the analysis results and lead to inconsistencies or errors in ...
GeoMesa is a cloud-based spatio-temporal database built on top of Apache Accumulo and Apache Hadoop (also supports Apache HBase, Google Bigtable, Apache Cassandra, and Apache Kafka). GeoMesa supports full OGC Simple Features and a GeoServer plugin. H2 supports geometry types [10] and spatial indices [11] as of version 1.3.173 (2013-07-28).
A GIS system to create, visualize, manage, and analyze spatial data. Supports desktop, web, and mobile applications. In addition to spatial data editing and visualization, ArcGIS provides spatial analysis and modeling features including overlay, surface, proximity, suitability, and network analysis, as well as interpolation analysis and other ...
A coverage is the digital representation of some spatio-temporal phenomenon.ISO 19123 provides the definition: [a] feature that acts as a function to return values from its range for any direct position within its spatial, temporal or spatiotemporal domain
GIS uses spatio-temporal location as the key index variable for all other information. Just as a relational database containing text or numbers can relate many different tables using common key index variables, GIS can relate otherwise unrelated information by using location as the key index variable.
