地理空间查询
基于地理数据的查询
Redis 开源版中的地理空间功能允许您查询与地理位置相关的数据。您可以查询特定半径内的位置，或基于多边形等几何形状进行查询。例如，多边形形状可以表示湖泊或建筑物的布局。
本文中的示例使用以下模式
| 字段名 | 字段类型 |
|---|---|
store_location |
GEO |
pickup_zone |
GEOSHAPE |
注意
使用 GEOSHAPE 字段类型需要 Redis 7.2.0 或更高版本。半径
通过将中心坐标（经度、纬度）、半径和距离单位传递给 FT.SEARCH 命令，您可以构建半径查询。
FT.SEARCH index "@geo_field:[lon lat radius unit]"
允许的单位有 m、km、mi 和 ft。
以下查询查找伦敦周边 20 英里半径内的所有自行车商店
FT.SEARCH idx:bicycle "@store_location:[-0.1778 51.5524 20 mi]"您是否厌倦了使用 redis-cli？试试 Redis Insight - Redis 的开发者 GUI。

形状
唯一支持的形状是点和多边形。您可以查询包含给定几何形状的多边形或点，或位于给定几何形状内的多边形或点。
FT.SEARCH index "@geo_shape_field:[{WITHIN|CONTAINS|INTERSECTS|DISJOINT} $shape] PARAMS 2 shape "shape_as_wkt" DIALECT 3
以下是对此查询更详细的解释
- 字段名：您需要将
geo_shape_field替换为您要查询的GEOSHAPE字段名。 - 空间运算符：空间运算符定义了数据库中的形状与您正在搜索的形状之间的关系。您可以使用
WITHIN、CONTAINS、INTERSECTS或DISJOINT。WITHIN查找数据库中位于给定形状内的任何形状。CONTAINS查询环绕给定形状的任何形状。INTERSECTS查找与提供的形状具有共同坐标的任何形状。DISJOINT查找与提供的形状没有共同点的任何形状。INTERSECTS和DISJOINT在 v2.10 中引入。 - 参数：查询引用了一个名为
shape的参数。您可以在此处使用任何参数名。您需要使用PARAMS子句来设置参数值。该值遵循几何体的 WKT 表示法（Well-known text representation）。支持的类型有POINT(x y)和POLYGON((x1 y1, x2 y2, ...))。 - 方言：基于形状的查询自查询方言第三版起可用。
以下示例查询验证自行车是否在取货区内
