Settlement Place Matching Quality Evaluation Method Based on Geometric Accuracy

空间数据匹配是空间数据更新与维护的基础和关键。针对空间数据匹配质量评估方法欠缺的现状，以居民地为例，提出了基于几何精度的居民地匹配质量评估方法。通过分析居民地匹配质量问题的内涵，确定了以几何精度作为依据的评估方法；结合居民地匹配质量评估特点，改进一般矢量数据质量评估中的缺陷扣分模型，得到了居民地几何匹配质量评估缺陷扣分模型，从而建立了居民地几何匹配质量评分评级模型。实验表明，该方法可以有效地完成居民地匹配质量评估，具有较强的可行性和实用性。

Spatial data matching plays a basic and key part in spatial data update and maintenance. In order to solve the current problem of lacking ways of evaluating spatial data matching quality, a method to evaluate the quality of settlement place matching based on geometric accuracy is put forward in this paper. The connotation of settlement place matching quality problem is analyzed, and the evaluation method based on geometric accuracy is decided. According to the characteristics of settlement matching quality evaluation, the defect marking model for vector data quality evaluation is improved, and a model for settlement matching quality evaluation is obtained. Finally, the settlement geometric matching quality score rating model is established. The experiment results show that the method is effective and practicable in settlement matching quality evaluation.
