[Geocoding] Help needed for setting up Reverse Geocoding Database using OpenStreetMap Data

[Sumit Gulati]

Hi,

 

Thanks for your email and the links which you have provided. We do not want to install full planet OSM data but we would like to install data for GCC States only. So we have downloaded pbf file for GCC states (gcc-states-latest.osm.pbf) from http://download.geofabrik.de/. Pls suggest how to setup reverse geocoding database to get the correct address using a latitude and longitude coordinates using this pbf file of GCC States.

 

Best regards

Sumit Gulati

Hi,

 

Yes, there seems to be a slight difference when returning the city

 

 <http://nominatim.openstreetmap.org/reverse?format=xml&lat=25.236545&lon=55.291413&addressdetails=1> http://nominatim.openstreetmap.org/reverse?format=xml&lat=25.236545&lon=55.291413&addressdetails=1

 

     "road": "Sheikh Khalifa Bin Zayed Street",

     "residential": "Al Mankhool",

     "suburb": "Al Mankhool",

     "city": "Dubai",      <===

     "state": "دبي‎",        <===

     "postcode": "41974",

     "country": "United Arab Emirates",

     "country_code": "ae"

 

 

compared to

 

 <http://open.mapquestapi.com/nominatim/v1/reverse?format=json&lat=25.236545&lon=55.291413&addressdetails=1> http://open.mapquestapi.com/nominatim/v1/reverse?format=json&lat=25.236545&lon=55.291413&addressdetails=1

 

     "road": "Sheikh Khalifa Bin Zayed Street",

     "residential": "Al Mankhool",

     "suburb": "Al Mankhool",

     "city": "Sharjah",         <===

     "postcode": "41974",

     "country": "United Arab Emirates",

     "country_code": "ae"

 

My recent installation (behind a firewall) returns what  <http://nominatim.openstreetmap.org/> http://nominatim.openstreetmap.org/ is returning.

 

 

The installation instructions are on

 <http://wiki.openstreetmap.org/wiki/Nominatim/Installation> http://wiki.openstreetmap.org/wiki/Nominatim/Installation

Note that part about hardware requirements before you attempt to run in on an underpowered desktop or laptop or in a virtual machine.
