Representación de un mapa mediante Feature Service Response
Puede utilizar la respuesta generada de una solicitud de Feature Service (una función), como parte de una solicitud de RenderMap, que representa esta función. Cuando se envía una solicitud de Feature Service, por ejemplo:
Solicitud de Feature Service:
GET http://<hostname>:<port>/rest/Spatial/FeatureService/tables/features.json?q=select%20Obj,Country,Capital%20from%20%22/Samples/NamedTables/WorldTable%22%20where%20Country=%27Andorra%27
Content-type: application/json
Authorization: <Basic or Spectrum Token>Recibirá una respuesta de Feature Service. Sin embargo, solo quiere pasar parte de esta respuesta a la solicitud de RenderMap. Debe utilizar FeatureCollection (la función) completa que desea procesar.

Ahora puede utilizar la solicitud de Mapping Service RenderMap para representar la función. Los datos POST de la solicitud de RenderMap se describen a continuación: Render Map. La respuesta Feature Service (como se describió anteriormente) formará el cuerpo POST json de la solicitud REST.
El formato a continuación se utiliza para solicitudes HTTP POST:
HTTP POST: /maps/image.image type;
POST DATA: w=width;h=height;c=x,y,srs;z=zoom;s=scale;b=x1,y1,x2,y2,srs;
[r=resolution];[l=locale];[bc=background color];[bo=background opacity];
POST BODY: Content-Type:application/json {FeatureCollection}
POST http://<hostname>:<port>/rest/Spatial/MappingService/maps/image.png;w=800;h=600;b=1.42,42.23,1.77,42.85,epsg:4326;
Content-type: application/json
Authorization: <Basic or Spectrum Token>
Body: <FeatureCollection returned from Feature Service response>
