我正在整个城市创建一个可公开访问的水域的网络应用程序。这将包括饮水机，水瓶加油站，游泳池等（我们称这些＆＃39;访问类型＆＃39;）。
我已经在数据库中完成了所有工作，使用PHP生成GeoJSON，它可以正常工作（意思是，我可以调用它并通过Mapbox GL显示信息）。
我仍然坚持如何处理显示/过滤图层/标记/图标。我已经关注了Mapbox的商店定位器＆＃39;和＆＃39;过滤＆＃39;教程，我已经在基础层面上工作了，但这些都似乎在假设每个位置可以/应该只有一个访问类型的情况下运行，并显示每个地址的倍数当有多个（堆叠图标并显示重复地址的巨大列表）时。
我是否应该使用我的数据库查询进行分组，创建包含不同访问类型的子数组（对象）（在下面称为＆＃39; icon＆＃39;），或者单独提取所有内容（见下文），然后排序它w / javascript / jquery？
