多边形内的 Socrata SODA 过于复杂

Question

对 inside_polygon 使用 Socrata SODA api 会引发错误，指出它太复杂。

https://www.dallasopendata.com/resource/x9pz-kdq9.json?$where=within_polygon(location,%20%27MULTIPOLYGON%20(((-96.79920%2032.77946,-96.807768%2032.7751,-96.7999%2032.76999,-96.79920%2032.77946)))%27)

{
  "code" : "query.execution.queryTooComplex",
  "error" : true,
  "message" : "Only simple comparison filters are allowed",
  "data" : {
    "reason" : "validation.complex-filter"
  }
}

这是一个工作版本：

Answer 1

您使用的是旧 API 端点，而不是支持 within_polygon(...) 的新端点。你会想要使用this one instead。该查询针对该新端点按预期工作：

https://www.dallasopendata.com/resource/5nug-crr9.json?$where=within_polygon(location,%20%27MULTIPOLYGON%20(((-96.79920%2032.77946,-96.807768%2032.7751,-96.7999%2032.76999,-96.79920%2032.77946)))%27)
