In the KMLStyler, there is an option Allow Unique Styles Per Feature, where you specify whether you want to have one single style for all features or a style for every feature, i.e. 10 lines of code in the header of your KML file, or 10 lines of code for every feature!

Although having one single style is often insufficient, you could create a separate KML for each style class, e.g. one for each interval or each subtype, unticking that aforementioned option!

  • 减少属性的数量,例如使用attributekeeper
  • 简化了您的几何形状,例如使用普雷改装器
  • 将文件转换为(dumb)图像。

    中的任何一个都将降低数据的质量。如果您不想要,您可以将文件拆分为文件/图块的集合。查看https://knowledge.sa亚搏在线fe.com/articles/887/ptimization-large-datasets-for-kml-andagoogle-earth.html(要小心:这是非常高级的,带我一段时间到掌握)
