Removing _msgid from object

Why do you want to remove it?

by removing it i will be able to plot latitude and longitude on worldmap.

Having it there will not affect the worldmap node.

so by not removing _msgid also still i am not able to see coordinates on worldmap.

To repeat what @Colin said

...the presence of _msgid in the msg object has nothing to do with seeing or not "seeing coordinates on worldmap".

I suggest you either rename this thread OR start a new thread with the title "not seeing coordinates on worldmap" so that the right people with worldmap experience read the thread.

yes @steve sure i will create new a thread definately. :blush:
