Transaction Processing on Planar Partition for Cadastral Application
The paper presents how rules for geometrical and topological consistency of planar partition can be implemented and used for on-line testing of consistency of updates in a planar partition based transaction processing system. Upon the reception of a set of polygons as potential new version for a designated subset of the planar partition, the system does all the necessary geometry testing, does the on-line half-edge topology extraction and finally tests the new version of half-edges for internal (within itself) and external topology (the rest of the planar partition). Also, in order to prevent performance degradation in case large area becomes the subject to change, an in-memory spatial index is created on-line, and used for primary filtering. In case topological or geometrical errors are detected a log describing those is created and stored so the initial creator of the transaction or any other person can use it to correct the errors. Otherwise the transaction is either marked as valid or executed. The benefit of such an approach is its capability to receive prepared transactions from any software capable of producing polygonal data in a standard form and to automatically detect errors, description of which is logged for any later usage (primarily correcting).
