displaying googlemaps in Qt Offline Applications

[sumi]

In my application it is required to download the googlemaps and display it offline. The downloaded maps should have sufficient resolution for Zooming and the map should be retrieved based on lat/lon given. Please help me.
Thank you

You best talk to Google about a licence to do that before you go much further. The Google Maps API terms of service constrain your permission to do this, see 10.1.3 Restrictions against Data Export or Copying (https://developers.google.com/maps/terms#section_10_1_3).

Thanks for the reply. Is there any map servers who permits to download maps without any license agreement?

Without a licence agreement? I am not aware of any. With a permissive licence, sure. Try OpenStreetMap (http://www.openstreetmap.org/). Whether their data is suitable is another issue.
