Abstract: The paper presents a distance-based inverse deduction algorithm for site data based on distance-based process algorithm and long-flag hashing algorithm. For giving two parameters, any input point on site data line and relative distance from it, it can get corresponding output point in the way of judging the segmentation and the region divided by long-flag inside the segmentation in both of which it locates to calculate the distance parameters from the output point to the region logic start point. Namely, users can get the output point automatically by the input point and its relative distance without any additional configuration so as to extend the site data process functionalities. The paper also looks forward to the algorithm’s detail application and plan for site data.

摘要: 在基于距离的线路数据处理算法和基于散列的长链算法的基础上,提出一种基于距离的线路数据反推算法。给定在线路数据上任意输入点和距离此输入点的相对距离参数,通过判断出输出点处于的线路分段及段内由长链分隔开的区间,计算出其距离区间逻辑起点的参数,获得对应的线路输出点。即根据输入点和相对距离自动得到输出点,而不需要用户做任何额外的配置工作,从而扩展用户对于线路数据的处理功能。对此算法在线路数据的具体应用,提出进一步的展望和规划。
