1 简介
GoTrackIt基于改进的隐马尔可夫模型(HMM)实现了连续GPS点位的概率建模，利用这个包可以轻松对GPS数据进行地图匹配，本开源包的特点如下:
😻数据无忧
- 提供路网生产模块以及大量路网处理优化工具，您不需要准备任何路网和GPS数据即可玩转地图匹配；
- 提供GPS样例数据生产模块，解决没有GPS数据的难题；
- 提供GPS数据清洗接口，包括行程切分、滤波平滑、停留点识别、点位增密等功能。
☑️文档齐全
- 中文文档，有详细的操作指引；
- 算法原理讲解部分不涉及复杂的公式推导，使用动画形式剖析算法原理,简洁明了。
🚀匹配算法优化
- 支持基于路径预计算的FastMapMatching、支持多核并行匹配、支持网格参数搜索；
- 对基于HMM匹配的初步路径进行了优化，对于不连通的位置会自动搜路补全，对于实际路网不连通的位置会输出警告信息，方便用户回溯问题。
🌈匹配结果支持动画可视化
- 匹配结果提供三种输出形式：GPS点匹配结果表(csv)、匹配结果矢量化图层、矢量图层匹配动画(HTML文件)，HTML动画方便用户直观地感受匹配结果，同时可以提高问题排查的效率。
