Hi Marc,
I have a question for you. Do you think it would be possible for you to create two new webservices:
- getParent (geonameId) returning the geoId of the parent division
- getChildren(geonameId) returning the list that contains all geoIds

It will solve a lot of problems for my project.

thank you very much,
fabrizio

Hi Fabrizio

There is a service called hierarchy that returns all ancestors of a geonameId. Here the hierarchy for Segesta :
Europe > Italian Republic > Regione Autonoma Siciliana > Provincia di Trapani > Calatafimi-Segesta
http://ws.geonames.org/hierarchy?geonameId=6535960

And one called children to return the ADMs within another ADM. Here the regions of Italy :
http://ws.geonames.org/children?geonameId=3175395

Cheers

Marc

Hi Marc,
my tree navigation system is almost completed, you are able to walk up and down throughout the wolrd's administration divisions.
But I am not able to predict if a specific place has children or not. Would it be possible to have a flag to understand weather a place gotten by children webservice has children or not?
So I could put a link for expansion just for places with children.

Thank you very much
Fabrizio

Hi,
I really need some help to complete my project.
To determine weather a place has children or not is vital for my goal. May anyone give me some advice?
I use getchildren web service to obtain a list of places, but I don't know if they are father.

Thank you
marc

You are absolutely right. I didn't forget your posting. The number of children for the features returned by this service is required. I will see how fast I can implement it.

Cheers

Marc
