摘要
路网核查指利用各种技术手段,核实各地上报路网数据的真实性,传统的核查方法包括人工外业抽查,人工内业对比等方法,效率较低。本文通过一种“全自动排查 + 疑似人工复核”的方式提升路网核查效率,并提出定量化参考评价指标,消除不同作业人员评判标准不一致导致的核查结果差异。高速发展的浮动车时空轨迹结合高分辨率遥感技术是一种方便的解决方案。
Road network verification refers to the use of various technical means to verify the authenticity of road network data reported by different regions. The traditional verification methods include manual field inspection, manual field comparison and other methods, with low efficiency. In this paper, a “full-automatic screening + suspected manual review” method is used to improve the effi-ciency of road network verification, and a quantitative reference evaluation index is proposed to eliminate the difference of verification results caused by the different evaluation standards of dif-ferent operators. It is a convenient solution to utilize the high-speed development of space-time trajectory of floating car and high-resolution remote sensing technology.
