developing an application using latitude and longtitude

[weihaojoshua]

Hi everyone.I am a newcomer on the nokia forum.I am currently trying to create a symbian c++ application to calculate distance between two points using geograpihical coordinates(longtitude and latitude)

How it works is that i would like to input coordinates and following that the application will be able to calculate the distance between my current location and the coordinates i just entered. Is is possible to create such an application? thanks

Of course it is possible to create such an application.

All you need is:
- a form through which the user can enter the coordinates
- a routine that uses the proper algorithm to do the calculation
- display the result

See the various "getting started" documents, tutorials and examples on this site (including the wiki) and the S60 C++ SDK.

And if you don't know how to calculate the distance between two points on Earth, search for the correct algorithms in suitable text books ( most that deal with the math around navigation on the seas, for example ), or the Internet ( e.g., http://codesearch.google.com/ ).

It seems you are beginner. If you are uisng J2ME then create the object of Form class. Please read some UI api from any book before you start development.
