          Dear FIWARE coach,
          we forward you a support request received from a CreatiFI applicant we are

          Hi,

          We are using POI Data Provider GE in order to handle pois in our
          application and CreatiFI OC1 is finishing.

          Related to the API (
          http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/POI_Data_Provider_Open_API_Specification)
          we need some clarifications:

          1)which order is adopted to return pois in "radial_search" method? (by
          distance from the center ? any other?)

          2)is it possible to extend response json structure in order to return also
          the distance from the center?

          thanks in advance

          Stefano

              CreatiFI phase 1 finishes in few days.
              The developer needs an answer asap.
              Could you provide some hints?
              Thanks in advance.

              • Data from searches are provided in no particuar order.
              • About distance: Distance is not an attribute of a POI. It is about the relation of the POI and the query parameters. The distance can be calculated by the haversine formula https://en.wikipedia.org/wiki/Great-circle_distance in the client application. Calculation of distance in the server is not planned.
              • You may sort the POIs in the client by the distance, if needed. E.g.:
                • Encapsulate the POI UUIDs with distances to an array (JavaScript example): 
                  [{distance: 738.5, uuid: "ac98fcf7-5280-44d1-bb25-c4627387c86c"}, ... ]
                • Sort the array 
                  distances_and_uuids.sort(function(a, b){return a.distance - b.distance});

              The needed operations are recommended to be done in the client application.
