Cesium加载高速公路样式线图层和利用CSS撰写高速公路样式

在ArcGIS软件中是将多个线图层叠加（宽的叠加在下方防止遮盖其他图层）    依照此想法在Cesium中加载高速公路线图层时 在 Cesium 中，直接设置线（如 Polyline）的样式为“高速公路样式”并不直接支持，因为 Cesium 没有内置的特定于高速公路的样式选项。不过，你可以通过自定义线的样式来模拟高速公路的外观，包括在线的外边界添加黑色描边。 要在 Cesium 中实现

Origin制图——点线图转换为叠层图

1.当我们绘制点线图的时候我们发现，当数据差距较大或者差距较小的时候，绘制的图会很难看，如下图所示。怎么样才能更好的表达图的意思并且好看。那么接下来分享一下最新学习的叠层图教学。 2.首先我们还是按照点线图的画图方法，将点线图优化。简单优化后的数据图如下所示。可以看到这是很紧密的，也十分的不好看，因此我们需要对数据进行分层。 3.点击右上角的图层分层。原始是2行2列，我们只需要4行1列（4个
