Sažetak
One of the most successful applications of GIS technology is in the field of land management. A lot of corporate GIS databases are in development ; they support the legal management and distribution of geospatial data. The representation of time within GIS is still an important and expected development to make these systems more suited to the temporal analysis of cadastral objects. Time integration within GIS requires a comprehensive analysis of spatio-temporal phenomena. The traditional short transaction-based concurrency control and locking techniques have proved insufficient for applications requiring long transaction management. This is especially true when multiple users must access the same database. Data edits or updates of the map database in cadastre may take hours or days. During such long term edits or database updates, users want to be assured that others do not inadvertently edit the same rows of data or feature instances that have been included in a long transaction. Cadastre needs the capability to version data and requires that the different versions of a row or feature instance be persisted for very long periods of time, and users should have a possibility to be able to view data as it existed at any specific moment in time. This translates into the need to have the capability to manage the temporal properties and aspects of feature instances/rows in a database management system. Modern temporal GIS for cadastre should implement a complete long transaction event that maintains atomicity and concurrency. Data changes are made through revision sets which can be exclusive for one user or shared among several database users. Users are permitted to create new versions of data to update, while maintaining a copy of the old data. The ongoing results of the long transaction are stored persistently, assuring concurrency and consistency.
