Fetching JSON data via AJAX, how to filter by population?

mattis — GMT

Hi! I am trying to remove all the fcode > PPL that have population=0 (because obviously there's not three Stockholms' in Sweden (the two wrong locations have population = 0). Here's part the code that fetches the data: Code:

$.getJSON("http://ws.geonames.org/searchJSON?",
			{ 'name': 'stockholm',
			'maxRows': 10,
			'fcode': 'PPL*',
			'population': '0',
			'type': 'json'},

As you see, I am messing around with the population variable. Can it be sent to the geonames service? Thank you in advance.

The search service does not support a parameter 'population'. Why shouldn't there not be three places called 'Stockholm' in Sweden? If the population of a place is unknown then it just means that it is probably a small place it does not mean the place does not exist. This wouldn't make any sense. Marc

Darned. I think you are right. I even looked into a Swedish atlas but it didn't have them. Finally I looked into the Swedish map service Eniro, and yeah, there it is and the coordinates match up pretty well. Thank you Marc. Do you know any way that I could filter out only the "real" cities/towns out of the database?

You may have a look to the dump directory : http://download.geonames.org/export/dump/ especially those files : - cities1000.zip : all cities with a population > 1000 (ca 80.000) - cities5000.zip : all cities with a population > 5000 (ca 40.000) - cities15000.zip : all cities with a population > 15000 (ca 20.000) You may also use search webservice, then filter result to keep only places with population > n

Yep, I am filtering it on my end of the transaction now. I just wanted to minimize the traffic. Thank you guys!
