摘要
在分析乡镇众源地理数据的质量特征的基础上,构建了一种基于实景三维的数据质量一致性评估框架。该框架包括具体的评估指标、评估方法以及评估流程,用Context Capture和DPMapper获取参考数据,并且使用ArcGIS评估数据的质量一致性程度。结果表明,高精度实景三维模型不仅能够作为数据质量一致性的参考数据,其特有的直观、准确、快捷、全面特征,还能作为新数据获取良好数据源。
Based on the analysis of the quality characteristics of township geographic data,a data quality consistency assessment framework based on 3d real scene was constructed.The framework includes specific evaluation indicators,evaluation methods,and evaluation process.Context Capture and DP-Mapper are used to obtain reference data,and ArcGIS is used to evaluate the quality consistency of data.The results show that the high-precision real-scene 3D model can not only be used as reference data of data quality consistency,but also can be used as a good data source for new data acquisition.
