OSMN

A Ruby wrapper for the OpenStreetMap Nominatim API.

Nominatim is a tool to search osm data by name and address and to generate synthetic addresses of osm points (reverse geocoding).

Service can be found at http://nominatim.openstreetmap.org API Details can be found at http://wiki.openstreetmap.org/wiki/Nominatim

$ gem install osmn

# search for a place
OSMN::search('135 pilkington avenue, birmingham')

# convert latitude and longitude into a place
OSMN::reverse_geocode(52.5487429714954, -1.81602098644987)

# search for address
# required params: q (the query)
search = OSMN::Search.new(:q => '135 pilkington avenue, birmingham')
search.params = {:limit => 1}

# you can revise the params used
search.params
# >> {:q => '135 pilkington avenue, birmingham', :limit => 1}

# and if all is ok, you can execute the query
search.search

You can set any parameter defined in the Nominatim wiki page (http://wiki.openstreetmap.org/wiki/Nominatim#Parameters)

# example parameters
params = {
    :q => '135 pilkington avenue, birmingham', 
    :'accept-language' >= 'en', 
    :countrycodes => 'gb', 
    :bounded => 1, 
    :polygon => 1, 
    :addressdetails => 1
}

# convert lat and long
# required params: lat, lon (latitude and longitude)
search = OSMN::Reverse.new(:lat => 52.5487429714954)
search.params = {:lon => -1.81602098644987}

# check the params
search.params
# >> {:lat => 52.5487429714954, :lon => -1.81602098644987}

# run the query
search.reverse_geocode

You can set any parameter defined in the Nominatim wiki page (http://wiki.openstreetmap.org/wiki/Nominatim#Parameters_2)

# example parameters
params = {
    :lat => 52.5487429714954, 
    :lon => -1.81602098644987, 
    :'accept-language' => 'en', 
    :osm_type => 'W', 
    :zoom => 18, 
    :addressdetails => 1
}
