Attempt at Automation of GIS Spatial Data Quality Check

In order to ensure the accuracy and precision of the data expression,the integrity,normalization and consistency of the data organization,the feasibility of the data application,etc. We must check the quality of GIS spatial data. This paper discussed data check of GIS spatial data,analyzed the source of the data error,the mode and the way to check data. And the data check module is programmed to check the test data,the result of the test showed us that the way of data check is feasible.
