Leaflet 将纬度替换为经度

我得到的多边形几何作为文本显示第一经度，纬度。。。我正在创建GeoJSON并在传单上绘图。。。但传单的标准先是纬度，然后是经度。我正在使用PostGIS如何更改多边形。。。如果我有点几何图形，我可以很容易地更改点的

st_x

，

st_y

。。。。但在这里，我想更改为多边形的整体边界，我创建的goem是

[[72.96699,31.96872],[72.9679,31.9669]]

而我想转换为

[[31.96872,72.96699],[31.9669,72.9679]]    

总的来说，我的问题是

(SELECT row_to_json(fc)
     FROM ( SELECT 'FeatureCollection' As type, array_to_json(array_agg(f)) As features
     FROM (SELECT 'Feature' As type
      , st_asgeojson(lg.geom , 5 ,0)::json As geometry
      , row_to_json((SELECT l FROM (SELECT id, distt_name) As l
        )) As properties
     FROM (SELECT gid as id, distt_name , geom FROM tbl_districts 
      where distt_name like '%') As lg) As f )  
    As fc)

• 。看这里

  SELECT ST_AsGeoJSON( ST_MakePoint(1,2) );
               st_asgeojson             
  --------------------------------------
   {"type":"Point","coordinates":[1,2]}
  (1 row)
  

您应该使用

jsonb_build_object

和

ST_AsGeoJSON

生成GeoJSON
