OSM data import error into nominatim

Question

Hi everybody!

I have been trying, for days now, to import a set of osm data into nominatim. These data have been manually generated using the JOSM tool. The import seems to work smoothly, but, at the end I get the following output:

Stopping table: planet_osm_rels
Building index on table: planet_osm_rels
Stopping table: planet_osm_ways
Stopped table: planet_osm_ways in 0s
Stopping table: planet_osm_nodes
Stopped table: planet_osm_nodes in 0s
Stopped table: planet_osm_rels in 0s
node cache: stored: 7(100.00%), storage efficiency: 0.68% (dense blocks: 1, sparse nodes: 0), hit rate: -nan%

Osm2pgsql took 0s overall
ERROR: No Data
No Data

And, in the end, nothing is imported even though it seems.

A small sample of the data I am trying to import:

<node id='-9149' visible='true' lat='51.8386' lon='4.9578'>
   <tag k='electrical_capacity' v='12h' />
   <tag k='general_state' v='normal' />
   <tag k='name' v='Beatrixziekenhuis' />
   <tag k='number_of_men' v='1500' />
   <tag k='resource_availability' v='HIGH' />
   <tag k='state' v='1' />
   <tag k='telecom_availability' v='TRUE' />
   <tag k='type' v='hospital' />
</node>
<node id='-9202'  visible='true' lat='51.8456942144' lon='4.95328903198' />
<node id='-9203'  visible='true' lat='51.83503500628' lon='4.94672298431' />
<node id='-9204'  visible='true' lat='51.83020836571' lon='4.96204376221' />
<node id='-9205'  visible='true' lat='51.83697082115' lon='4.97406005859' />
<node id='-9206'  visible='true' lat='51.84625096935' lon='4.97860908508' />
<node id='-9207'  visible='true' lat='51.8456942144' lon='4.95328903198' />

<way id='-9208' visible='true'>
  <nd ref='-9202' />
  <nd ref='-9203' />
  <nd ref='-9204' />
  <nd ref='-9205' />
  <nd ref='-9206' />
  <nd ref='-9207' />
  <tag k='electricity_availability' v='TRUE' />
  <tag k='flood_vulnerability' v='350' />
  <tag k='general_state' v='normal' />
  <tag k='name' v='Gorinchem' />
  <tag k='number_of_men' v='1000' />
  <tag k='state' v='1' />
  <tag k='telecom_availability' v='TRUE' />
  <tag k='type' v='residentialarea' />
  <tag k='water_availability' v='TRUE' />
</way>

Any suggestions ? Anyone ever encountered this same issue ?

Nominatim doesn't index everything with a name (or ref) tag. It looks for places, streets and similar tag combinations. For some tags it uses a positive list of desired values, for others a negative list. That happens in the file output_gazetteer.cpp.

https://github.com/openstreetmap/osm2pgsql/blob/d0af11f267a202c7c1961c2061d121c726d8db3a/output-gazetteer.cpp

You can either change the logic in the process_tags method to treat all electrical lines like places. Or add a tag place=locality to all your data before importing. http://wiki.openstreetmap.org/wiki/Key:place

thanks for you reply. I played a bit around with tags, and finally managed to get something, the import was successful, and also some research operation works.

Still, it's not how I want yet. I want to have a node representing an hospital, in a specific city (e.g. Gorinchem) in a specific country.

This is the node, in the osm file, that I am using:

<node id='-9149' visible='true' lat='51.8386' lon='4.9578'>
<tag k="is_in" v="Gorinchem, The Netherlands"/>
<tag k="amenity" v="hospital"/>
<tag k="building" v="yes"/>
    <tag k='name' v='Beatrixziekenhuis' />
<tag k='addr:city' v='Gorinchem' />
<tag k='addr:country' v='NL' />
<tag k="addr:street" v="Banneweg"/>
<tag k="addr:postcode" v="4204AA"/>
<tag k="addr:housenumber" v="57"/>
 </node>

I also added information relative to the specific address.

Basically, I want to be able to perform a research operation that could return me the hospital present in that city, or in that country.

As far as I know the query should be:

  q=The+Netherlands[hospitals]

What am I missing in that node ?

Thanks

Did you import the city and country as well? The is_in key is a hint but the place still needs to exist in the Nominatim database to create a hierarchy.

The query format looks good

http://nominatim.openstreetmap.org/search.php?q=the+nederlands+%5Bhospitals%5D

Here's a list of all 'special phrases' that can be added to those square brackets. http://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases after you ran the http://wiki.openstreetmap.org/wiki/Nominatim/Installation#Add_special_phrases step of the installation.
