随着互联网及在线地图技术的不断发展,为了提升矢量数据的在线交互性,满足用户实时更新地图数据和可视化表达的需求,提出一种高效、实时的矢量数据在线读取、展示和编辑方法.通过文件分片组装和多线程技术,实现了在线、高效的大文件和多文件读取;基于Geotools和MyBatis-Plus框架实现矢量数据的热更新;通过建立空间索引和生成唯一ID,实现矢量数据的增量更新.实验证明,本方法可在浏览器中高效、实时地完成矢量数据的读取、展示和编辑,并且面对大文件和多文件时也能保持良好的性能.
An efficient and real-time method for online reading, display, and editing of vector data
As the Internet and online map technology continuously develop, this paper proposed an efficient and real-time method for online reading, display, and editing of vector data to enhance the online interactivity of vector data and meet the needs for real-time updating map data and visualization. First, through file fragmentation and multi-threading technology, the paper achieved an online and efficient reading of large and multiple files. Then, based on the Geotools and MyBatis-Plus framework, it implemented a hot update for vector data. Finally, by establishing spatial indexes and generating unique IDs, it realized incremental updates for vector data. Experiments have shown that the proposed method can efficiently and real-time read, display, and edit vector data in a browser and can maintain good performance even when facing large and multiple files.
