Erwin, Confused: I thought all along that the subject about the admin-polygon-relation's center (whatever that means). :-) That normally, in the absence of a member 'admin_centre' node in the relation, the name-TEXT of that administrative polygon is rendered in its geometric center.
BUT, assigning a node as the admin_centre of an administrative_relation, will for some reason render the TEXT value at the assigned 'location' of said node. Which in most cases happens to be the place_name. Isn't that the idea of Maning's question? hmmmm What's the difference if there's any? can you explain? (with example please - yung pang elementary) for the benefit of the likes of me who are too lazy to read the manual, hehe Rally On Thu, Jul 2, 2015 at 2:46 PM, Erwin Olario <[email protected]> wrote: > > Rally, Maning is asking about the administrative centres, and that would > mean government authorities in charge of administration.
