hi linux-experts,
relatively new to GIS and Openstreetmap i try out techniques with perl, php, ruby and some other toosl /(osmconvert and filter) in order to get familar with the techniques.
what if i need the a country and not only a part of it what do i need to edit in the boundary-box.
let me say i want to gather data from
a. Belgium b. Argentina c. Colombia d. Denmark
what do i do with the boundary-box (see below in the code)
can i enter some equivalent.
if i need to explain more - just write ...
Code:
require 'open-uri'
require "net/http"
require 'rexml/document'
def query_overpass(object_type, left,bottom,right,top, key, value)
base_url = "http://www.overpass-api.de/api/xapi?"
query_string = "#{object_type}[bbox=#{left},#{bottom},#{right},#{top}][#{key}=#{value}]"
url = "#{base_url}#{URI.encode(query_string)}"
resp = Net::HTTP.get_response(URI.parse(url))
data = resp.body
return data
end
love to hear frrom you - look forward to any and all help!
update:
found out some interesting things- have a closer look here;

User:The Anome/country bounding boxes A first hack, based on all places in the NGA GNS dataset, not (yet) properly handling latitude wrap-round at ±180°. Country names are mapped from FIPS country codes. This works pretty well for all countries that do not cross the 180° meridian. Russia is a notable exception. This dataset does not include the United States.
