Do you want to connect to external service using PRPC ? or do you want create a service which gives distance of two places using location ?

This answer made things a little less clear for me.
To clarify the question from Gangababu, what things on this list will users of your application need to do?:
- use the application within a web browser / phone app and enter the parameters, then see a result in the UI
- call a new Service that will exist on your Pega system, which they will use to get the data using client software of some sort
I think you are talking about # 1.
In that case, you will need to use a Connector feature such as Connect REST, and call the remote API of your choice in order to get the data for use in your application logic.
In Pega 7 you may use a Wizard (Designer Studio Button -> Integration-> New REST Integration) to quickly and easily generate the artifacts you need.
Please share the version of Pega that you are using to help people accurately answer your question.
Now the question is, do you want to create this service in PRPC? Or you want to use JAX-WS/RS/ Apache-CXF framework to do it from an external service running on your application server? Nevertheless look into Google map API which returns data in JSON using REST:

If you want to calculate the distance in PRPC and not have to depend on external service provider to do the calculation, you can use the latitude and longitude of the locations to plug into the Haversine formula (Haversine formula - Wikipedia, the free encyclopedia) to calculate distance. The Haversine formula does not take into account that the earth is a slightly squashed sphere, but there are formulas that do if you need the extra accuracy.
Hi Prashanth,
You want to begin with taking the Integration course with Pega academy. That will give you a solid background on integrating 3rd party services with Pega and similarly developing services in Pega.
