[Former Member]

HI Expert,

I need your help on one development,

i want to develop a program in SAP ABAP to get latitude & longitude of a particular place,

I have a street name, city, pincode & country which i pass it to http://itouchmap.com/latlong.html

and get Latitude & longitude of the User but I am performing this activity manually and i want to do it through ABAP program.

i need a way to fetch Lat Long from web link & show as a output of the ABAP report.

Please check the attcahed file which contain manual process of my current activity.

Thanks & Regards,

You can call the Google Maps API for the Geocoding. You would need the API key from google.  If it is for a client, you should get the client account for more usages. Once you have the key, you can try to do the HTTP call.

Refer for Geo coding call:

The Google Geocoding API - Google Maps Geocoding API — Google Developers

In ABAP, make the HTTP call using the CL_HTTP_CLIENT. There are quite a few examples around the web for this, but you can reference

for HTTP calls.

  CALL METHOD cl_http_client=>create_by_url
    EXPORTING
      url                = url
    IMPORTING
      client             = http_client
    EXCEPTIONS
      argument_not_found = 1
      plugin_not_active  = 2
 internal_error     = 3
      OTHERS             = 4.
  IF sy-subrc = 0.
    http_client->send( ).
    http_client->receive( ).
    content = http_client->response->get_data( ).
    http_client->close( ).
  ENDIF.

Pass the URL like this.

https://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=API_KEY

Once you receive the content back, parse the content to get the desired values.

Hi ,

I have tried this but in content = http_client->response->get_data( ). i am not getting Latitude & longitude.

I have passed 'http://maps.google.com/maps/api/geocode/xml?address=3373 US HIGHWAY 1 STE 54A  LAWRENCEVILLE  08648-2414 NJ&sensor=false' in URL.

but not getting Latitude & longitude.

You need to replace the space with + in the address. Also, there should be comma after street, city, zip code and state.

So something like this:

url = `http://maps.googleapis.com/maps/api/geocode/xml?address=3373+US+HIGHWAY+1,+STE+54A,+LAWRENCEVILLE,+0...`.

I tried to run on my system but it gave me REQUEST_DENIED return code with message "Requests to this API must be over SSL.". So you need to send the request over HTTPS. Make sure your system is setup correctly to handle the HTTPS response.

Hi Subhanshu,

Getting Latitude and Longitude is possible using the website

http://maps.google.com/maps/api/geocode/xml?address=jeddah

This result is returned in xml format.

You have to parse the xml and take out Latitude and Longitude.

You can check the below code which is written by using the source

Hi Abdul,

I have tried your suggested code but not getting output.

I passed "http://maps.google.com/maps/api/geocode/xml?address=bangalore".

in  http_url .

* Creation of new IF_HTTP_Client object

     CALL METHOD cl_http_client=>create_by_url

       EXPORTING

         url                = http_url

       IMPORTING

         client             = http_client

       EXCEPTIONS

         argument_not_found = 1

         plugin_not_active  = 2

         internal_error     = 3

         OTHERS             = 4.

     http_client->request->set_header_field( name  = '~request_method'  value = 'GET' ).

* Send the request

     http_client->send( ).

* Reterive the result

     CALL METHOD http_client->receive

       EXCEPTIONS

         http_communication_failure = 1

         http_invalid_state         = 2

         http_processing_failed     = 3

         OTHERS                     = 4.

     p_content = http_client->response->get_cdata( ).

But i got in p_content

"<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">##<html>##<head>##<meta content="text/html; charset=ISO-8859-1"##   http-equiv="content-type">##<title>Proxy Warning</title>##<link rel="StyleSheet"##   href="http://blocked-sites.cso.att.com/".

I have checked manually the same URL(http://maps.google.com/maps/api/geocode/xml?address=bangalore".) , it is working .

Please check the below XML.
