Blog about the GeoNames project.
GeoNames.org is compiling a worldwide database of public domain geographical data from various sources. The GeoNames database is not only searchable and downloadable, but also directly accesible via numerous webservices free of charge. The database contains more than 6 Million toponyms in several layers, whereof ca 2.2 Mio populated places. For numerous countries postal code information is available and may be used for address geocoding.
The rss feed for the blog is here :

Hi there,
I have a question: could it be, that the database you’re using for the georss-service is a different one then the one you are offering on http://download.geonames.org/export/dump/ ? Because there are several cities I can get by using the rss-service, but not when I download the database.
And second, out of curiousity, your service is quite fast, but you must be searching through a database of millions and millions of records. How do you do that, in terms of performance?
thanx, Robert

Hi Robert
The database is exactly the same. Do you have an example for a city you are missing in the dump?
The search engine is using an inverted index. It is the same technique google and other search engines are using.
Cheers

I’m searching for a webservice which allows one to find a city via latitude and longitude.
Since you have all the information which is nessasary to implement such kind of service I would like to ask you to expand your http://ws.geonames.org/search interface with the parameters latitude and longitude.
Kind regards

Hi Lutz
What you are looking for is called ‘reverse geocoding’. Geonames has a couple of reverse geocoding web services :

How should we show attribution on our site if we use the GeoNames database?
thanks,

Hi Stephanie
A link on your site would be nice. You can put it where and how you see fit.
Kind regards

The current rssToGeoRSS web service includes the optional Country parameter. Could this service be extended to include an optional ‘Region (within Country)’ parameter ?
The problem is large countries (eg. Canada) with same (or similar) place names that exist in multiple regions (ie. provinces).
I’ve been experimenting with the rssToGeoRSS web service to show RSS newsfeeds on GoogleEarth. There are a number of cases where the identified place is either:
1. found in the wrong province (because my selected newsfeeds are province-specific), or
2. a secondary placename in the news article, but found ‘first’ by the web service.

You are right, Steven. An additional parameter could really help with focusing the parser on a particular region. There are many other way how the parser could be improved and I hope we will find the time to work more on it.

Hello Marc,
We are trying to correct some mistakes for areas in Greece and also to add some beaches in Greece but we are facing a problem. The ADM1 details of them are not updated correctly and are shown as GR.undefined although we have chosen a valid AMD1 element. To see what I mean, check these two search pages:
http://www.geonames.org/search.html?q=ADM2&country=GR
and
http://www.geonames.org/advanced-search.html?q=beach&country=GR&featureClass=T&continentCode=
Thank you in advance.
George.

Don’t know if this is right forum for this, but I am trying to do genealogy for father, born Sweden, emigrated USA 1921, age 19. Can find little stateside except passenger manifest of arrival listing Holmbergat Filipstad Sweden. Can’t locate “Holmbergat” or “Halonbergat” (latter listed as origin of aunt’s passenger documentation) anywhere. Anyone know where this was exactly relative to Filipstad? Appreciate all help.

Not sure if you’re going to get this, but “Halonbergat” looks like a transcription error, or perhaps it uses a regional dialect form which is no longer in use. The name should likely be Hallonberget (Hallon = raspberry, berget = the mountain, giving ‘The Raspberry Mountain’). The other one should be “Holmberget” would mean something like “The Islet Mountain.” Note that in Swedish those have to end with “et” and not “at” as you’ve written.
I checked with a Swedish mapping site but could find no modern reference to either one near Filipstad. It would likely be the name of a parish or homestead, and may no longer exist.

You have a very wrong population number for Huntsville Ontario Canada (7972). The number should be 19579, as quoted on the town website http://www.huntsville.ca/business/demographics_pop.htm using figures from the Financial Post (FP Markets

Thanks Eric, I see that someone has corrected the population number following your posting.

Hello,
Could you supply the IP ranges needed to access geonames from behind a firewalled server that is not open to internet in general?
Thanks
