Thanks. A contributor has confused the fips country codes for Bahamas (BF) with the ISO country code (BF) for Burkina Faso.

Cheers

Thanks. We have rerun our geocoding with a new improved version and deployed the new data set with the fixed coordinates.

We are processing polygons on the database layer (postgres/postgis) as we have a lot of them. You could also use a tool on the application side like the java topology suite: http://www.vividsolutions.com/jts/jtshome.htm

You could try to find the polygons of the official council boundaries and use them to reverse geocode your coordinates. And if you find them and they are releases under a license that allow us to use them, please let us know so that we can include them in our web service.

As I said in my previous post. You have to do the calculation yourself. I don't know of any inbuilt database function to do this. If you don't want to do this on the application level you can write a stored procedure to do this for you on the database level.

Marc

We use feature code, population, country, alternate names as indication of the relevancy of a city.

Marc

For the postal codes we have used the yahoo search web service to count the number of 'hits' for each name:

You could do the same thing with alternate names for places to get an impression of the popularity, at least the popularity on the web.

Hi Noiv

Glad to have you back after a long time.

There are a couple of levels between ADM1 and pplx in Geneva and they are missing for different reasons. ADM2 is missing because we did not yet have the time to update the admin2codes for Switzerland. ADM3 is missing because we are not allowed to use the information from the swiss government, as the data license does not permit it.
The PPL is missing because we have not yet had the resources to update our service to include the information pplx>ppl in the extendedFindNearby service.

Hi Atilla

There is a countrysubdiv service to tell you the state of a lat/lng:

Hi John

CS has been deleted from the main database as it politically no longer exists. We have kept it in countryInfos.txt as a reference (iso codes etc)

I am afraid, GeoNames does not have an address geocoding service.

Marc

Hi

You have to use the 'findNearesAddress' method on the WebService class:

Enjoy your holiday. See you in August.

Hi Molin

It is simple mathematics. Multiply with 60 to get the minutes, mulitply the remainder again with 60 to get the seconds.

Hi

As far as I know wikimapia is a pure end-user application with no api or download possibilities. GeoNames in contast is a developer resource. The goal of GeoNames is to provide application developers with data and webservices.

I agree with you that in the short term we will not have any good polygon data from official sources. Would you like to help develop a polygon edit interface?

The IATA codes for airports are in the alternatename table with a pseudo language code 'iata'.

The sql join looks ok. What we do, however, it not to join it at every select. We load the names into a cache and translate it at run time.

As for adm2, I think you have cut some characters. The column is longer than 4 chars.

GoogleMaps is using other data providers. The copy right note in the right lower corner tells you which provider is used for each tile.

Marc

Do you mean this one?

It is exactly at the same position googlemaps puts it.

Hi Mike

Thanks for offering to help.

The countryInfo.txt file is in the sourceforge csv:
http://geonames.cvs.sourceforge.net/geonames/data/

The files are generated daily from the database. You can edit the records with the edit interface:
