Sažetak
Extremely fast and dynamic changes in space require efficient and appropriate record-keeping of these. Records of spatial data without a time component give insight into data at a current moment and in their current condition in the field or records. By adding the time component (4th dimension) to spatial data, an additional function of spatial database is enabled. Spatial database becomes a spatio-temporal database and it is possible to send queries to the base which result in a set of data at a certain time moment. An appropriate data model enables sending two-direction temporal queries. Temporal queries enable simple research of changes in space through time, depending on wishes and needs. The availability and quality level of open-source software is an excellent basis for developing a model of spatio-temporal databases.
