    Building Offline Map Application in Mobile phones

    hello,

    I need to develop an application where i need maps, this map server can be any server for example i have my own maps server where i have map data.

    Now the problem is I have to build application, in which user can request for maps of specified location, and must be able to save it in his mobile phones so that he don't have to read it again from internet, and he can use those maps where there is no internet.

    Can anyone suggest how this can be done using J2ME?

    Looking for reply.

    Thank You

    Hi Amishra

    There is an example on Forum Nokia Wiki regarding use of Google Maps in your application.

    As for using your own map server what sort of map server you are using? if it is an OGC compliant map server then you can simply make a WMS request to the map server and then handle the returning tile(s) in your application. You will have to give bounding parameters as well when making the request to your map server and request PNG output form your map server. Please note that it will cost your users to query and receive this data on their phone.

    As for saving you will have to check first if data licence allows you to do so.

    Hi

    what map server you are using?

    Keep in mind that map data is licenced and will cost you or your company to host it and making it available to public/customers.

    Just think about your options as to what you want to achieve with this application. what are the goals? It is very critical as it might turn out that it is easier and cheaper for you to use Google rather than being responsible for maintaining a production map server. if simple map viewing is required then Google will do the job and it will not cost you to buy map data in.

    As for config steps it will be difficult to tell without knowing the scope and servers involved.

    thanks for the reply.


    If i want to use google map services then what are the steps that i have to do.

    there is API in wiki, but i didn't understood how to use that.

    can you tell me anything that i could consider while developing such applications, and what things i have to consider.

    Your little help will be a great thing to me. Looking for your reply.

    Thanks

    Re: Building Offline Map Application in Mobile phones

    Have a look at this example on Forum Nokia Wiki.
    http://wiki.forum.nokia.com/index.ph...oogle_Maps_API
    http://wiki.forum.nokia.com/index.ph...e_applications

    It has code that allows you to have a static map image and also provides functions to implement scroll support.

    An example midlet is also included to see it in action.

    As for saving for later viewing you will have to check if Google's Terms and Conditions of use allow you to do so. You will need to signup for a new GoogleMaps key for which you only need a valid Google account.

    Use of API is included at the end of the example. Add googlemaps class in the wiki example code to your source folder. Simply instantiate it and make necessary calls to retrieve the map.

    It is very clearly included at the end of this example.

    Have a play around with it and then if needed get back with specific questions and if you are able to make any improvements help the developer community by sharing your experience at Forum Nokia Wiki.

    Goodluck
