Suggestions Needed: FlashLite GIS Application

[SoulBlade]

Hello,
i desire to develop a Flashlite mobile GIS application. It's suppose to act as a Client to a Web Mapping service/server.
I wanted to ask how this could be done (i.e. developing of the flashlite client) . Directions to possible sample/example codes, whitepapers and the like, would be very much appreciated. thanks.

Hi,
can you specify which version of Flash Lite you are targeting and which platform of phones ?

This is a starting point :
http://wiki.forum.nokia.com/index.ph..._in_Flash_Lite

For Flash Lite 4 cases, you can use my tutorial -

Target platform: FlashLite 2.x -3.x. My users don't have FL 4 devices yet.
Target devices: Nokia S40 (.nfl), S60 (.sis), and some J2ME enabled devices (.jar).
I've already gone through some of the wiki content on LBS and its relation in Flashlite.

Actually what i want to build is suppose to be like a dynamic map application (as opposed to the 'static map' kind seen in some of the wiki content as well as the nokia FlashLite tutorials). Such that when the user pans the map on the device, the map re-renders. More like what you'd have on a desktop map application (i.e. interactive in-nature).
Users will be entering their location by themselves (before they can perform map queries and stuff like that), so the application won't be making use of GPS.

Then there's the issue of data transfer across the network. The mapping webservice i plan to use as the backend(on the server), for the application, gives an output of XML. XML , being very verbose in nature, isn't very well suited for the mobile app. so i was thinking of using 'flash remoting', but that seems to be only supported in FL 3.x upwards. Not FL 2.x.
Then there's the issue of building an in-client cache to hold some of the data, when the user runs the app offline, or just to enable faster rendering.
There're alot of issues. I'm just not so sure where to start. Was wondering if someone on the Forum had built a similar GIS mobile app. (maybe not neccessarily in FlashLite), if they could give some pointers and stuff like that.

Thanks for replies in advance.

'Google maps on Java or j2me' can be a good search as an alternative, considering the bulk of work in the projecct..

It's developing such an application in flashlite that's my problem. if there was maybe an open source project whose source code i could review/look at - it might help.
Already took a look at the document: "Builiding S60 Location Aware Applications",. but it still doesn't discuss implementation issues.
Will post the question in the LBS section...
