Geoserver上的动态SLD

Question

有人能帮我在geoserver上使用这个CSS sld吗？

如果有人有比我更好的选择，请建议。

[activity_group_id = 20] [application_status = 'PreSanction-Pending']{
mark:symbol('ttf://ESRI Business#39');
:symbol {
fill:#FF0000;
}
}
[activity_group_id = 20] [application_status = 'Payment-Done']{
mark:symbol('ttf://ESRI Business#39');
:symbol {
fill:#00FF00;
}
}
[activity_group_id = 20] [application_status = 'Work-Completed']{
mark:symbol('ttf://ESRI Business#39');
:symbol {
fill:#0000FF;
}
}
[activity_group_id = 20] [application_status = 'PreSanction-Received']{
mark:symbol('ttf://ESRI Business#39');
:symbol {
fill:#00FFFF;
}
}

这个很好用但是我想用if-then-else来简化这个我被这个卡住了

因为有30多个唯一的"activity_group_id">

我有点数据，其中每行有两个变量"activity_group_id"one_answers"activity_status"，我使用ttf符号显示为层，但条件是，每个点都需要根据其状态分配颜色(填充(总共有4个唯一值，因为我是sld参考文档的新手，但没有找到任何解决方案。

编辑：-为点位置层添加一些测试数据

activity_group_id application_status desk4_longitude desk4_latitude
20  "Work-Completed"    77.8912643252645    20.7848792063826
20  "PreSanction-Pending"   77.8912791454753    20.7796634062134
20  "Payment-Done"  77.874307404545 20.7786504284761
20  "PreSanction-Pending"   77.8748653559629    20.7777572907007
20  "Payment-Done"  77.8935239518168    20.7742195299066
20  "PreSanction-Pending"   77.8887775696933    20.7848194877974
20  "PreSanction-Received"  77.8829004567405    20.7622202218188

Answer 1

使用recode函数来简化样式。我不能测试它，但应该是这样的：

[activity_group_id = 20] {
mark:symbol('ttf://ESRI Business#39');
:symbol {
fill: recode(application_status, 
'Payment-Done', #00FF00,
'Work-Completed', #0000FF,
'PreSanction-Received', #00FFFF);
}
}

如果颜色根据application_status相同，但形状根据组id变化，则使用级联并设置单独的规则：

[activity_group_id = 20] {
mark:symbol('ttf://ESRI Business#39');
}
[activity_group_id = anotherId] {
mark:symbol('ttf://anotherSymbol');
}
* {
:symbol {
fill: recode(application_status, 
'Payment-Done', #00FF00,
'Work-Completed', #0000FF,
'PreSanction-Received', #00FFFF);
}
}
