Geo-polygon query-Tablestore(Tablestore)-阿里云帮助中心

GeoPolygonQuery filters rows by a polygonal geographic area. Tablestore returns rows where the value of the specified GeoPoint column falls within the defined polygon. Use this query type to filter data based on complex geographic boundaries, such as delivery zones, administrative districts, or service coverage areas.

Data structure

message GeoPolygonQuery {
    optional string field_name = 1;
    repeated string points = 2;
}

Parameter	Type	Required	Description
field_name	string	Yes	The name of the attribute column to query. The column type must be GeoPoint.
points	string	Yes	The coordinate pairs of the vertices that define the polygon. Each value must be in `latitude,longitude` format. Valid values of latitude: `[-90,+90]`. Valid values of longitude: `[-180,+180]`. For example, `35.8,-45.91`.

Important: The coordinate format is latitude,longitude — latitude comes first. This is the opposite of GeoJSON, which uses longitude,latitude order. Swapping the order is one of the most common sources of incorrect geo-polygon query results.
