Geoserver如何让图层标注基于规则显示

一、模拟需求

让图层标注根据不同比例尺度显示不同的标注及样式。

二、示例演示

官方说明文档

1.数据表准备

说明：我准备了三个字段来操作，你也可以一个字段，后面可以用过滤来区分字段内容

2.打开QGIS，打开图层属性

3.选择标注，基于规则标注

花点时间，每个tap都点开看看呗，按自己需求设置

操作如下图

4.QGIS效果
large

middle

small

上面示例，标注大小样式我没认真调，小伙伴们可以按自己需求DIY哦~

5.保存样式

6.加载至geoserver样式

7.图层预览

注意得是你设置样式的这个图层哦~

其它图层的话可能就得更改图层字段名或者sld文本里的标签名了
