国标矢量数据格式转换几何精度评估模型比较

摘要

This paper analyzes the processing of the national and military vector data conversion,finds out the main reasons of geometric precision loss in the data conversion,and puts forward to three kinds of evaluating-models of geometric precision loss for checking up the conversion processing.The experimental results indicate that the different results of three kinds of model under different data quantifies and data difficulties are related to the complexity of the model.%通过对国标矢量数据转换过程的分析,研究转换过程中几何精度损失的具体问题,提出了三种用于检验转换过程中几何精度损失的评估模型.实验结果表明,该评估模型在不同数据量和数据难度的情况下所产生的结果和模型的复杂度有较大关系.
