基于Geoserver的动态SLD

Question

有人能帮我解决这个在geoserver上的CSS sld吗？

如果有人有更好的选择，而不是我的方法，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;
    }
}

这很好，但我想简化一下，如果-那么-否则我就被困在这上面了。

因为有30多个独特的“activity_group_id”

我有点数据，每一行都有两个变量'activity_group_id‘和’activity‘，我使用ttf符号作为层显示，但条件是，每个点需要根据其状态分配颜色(Fill) --总共有4个唯一值，因为我对sld引用的文档并不熟悉，但没有找到任何解决方案。

编辑:-为点定位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

使用记录函数简化样式。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);
  }
}

如果基于application_status的颜色是相同的，但是形状是根据组id变化的，那么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);
  }
}

从您的参考资料来看，我检查了docs，并对您的答案的语法进行了一些修改，以供其他人使用。

检查geoserver css文档

/* @title Apiculture */
[activity_group_id = 20] {
  mark:symbol('ttf://ESRI Business#39');
  mark-size:15;
  :symbol {
     fill: [recode(application_status,
            'PreSanction-Pending','#FF0000',
           'Payment-Done', '#00FF00',
           'Work-Completed', '#0000FF',
           'PreSanction-Received', '#00FFFF')];
  }
}

/* @title Sprinkler Irrigation */
[activity_group_id = 19] {
  mark:symbol('ttf://ESRI Business#40');
  mark-size:15;
  :symbol {
     fill: [recode(application_status,
            'PreSanction-Pending','#FF0000',
           'Payment-Done', '#00FF00',
           'Work-Completed', '#0000FF',
           'PreSanction-Received', '#00FFFF')];
  }
}
