Land Parcel Identification System

Querying Attribute and Graphical Data
Basic queries can be performed either by entering the ID of a parcel or by clicking inside the parcel on the map. In the first case the map display is repositioned and rescaled on MBR of the requested parcel, the parcel is highlighted and its attribute data are shown in a table view. In the second case only highlighting is made and the attribute data are shown. Beside that, a tool named QueryBrowser, which is integrated into the thick client application, can be used for the definition and execution of queries. Results are displayed in a table and highlighted on the map.

User can save or restore a query as well as use queries managed by the system administrator. Automatic queries can also be defined (e.g. when a person is chosen then all parcels owned by him are highlighted).
