Quality checking method for spatial database based on domain knowledge and rule library——Taking the evaluation of land intensive use database as an example

Based on the systematical analysis and induction of the main factors which affect spatial database quality, the paper proposed that the rule library and the common quality checking model were built according to domain knowledge, metadata, topological relation, attribution and the relation of geometry and attribution for improving the checking efficiency of spatial database. On this basis,the database checking system for evaluation of land intensive use was developed to effectively control the database quality of evaluation of land intensive use.
