Abstract

The invention discloses a method for checking quality of universal space data based on rules and a system by adopting the method, wherein, the universal space data is used for forming a spatial database. The method comprises the following steps: receiving the input data to form the spatial database including spatial information and attribute information; designing a basic checking operator through the requirements of the data in the spatial database; formulating corresponding data checking rules according to a plurality of structure layers of the logical structure model of the spatial database and through applying the basic checking operator and combining parameter setting; formulating a data checking scheme according to the data requirements and the formulated data checking rules; and checking and outputting error information including various error terms. By adopting the invention, inspectors can conveniently formulate the data checking scheme according to the requirements of input data and data loading and obtain a corresponding error list, thereby obviously enhancing convenience of checking the data quality.

Description

technical field [0001] The invention relates to a rule-based universal spatial data quality inspection method and a spatial database data quality inspection system using the method. Specifically, the present invention relates to a spatial database data quality inspection method and system for inspecting the quality of spatial data using an inspection scheme formulated with inspection rules for data inspection requirements. Background technique [0002] In GIS, the integrity and accuracy of data, which exist in the data specification as fundamental, is the prerequisite for the reliable application of GIS and the basis for realizing the advanced functions of GIS. The quality of GIS data directly affects the economic and social benefits brought by the construction of the spatial database, and affects the correctness and reliability of all applications, analysis and decision-making based on the spatial database. [0003] In today's data production process, due to many participa...
