Extract all cities with lat and lon coords named in English

I need to extract all cities with lat lon coords from Czech Republic OSM with English names of suburb and cities.

This is how I imported OSM file downloaded from Geofabrik:

osm2pgsql --slim --username postgres --database gis --hstore clech-rebublic-latest.osm
psql -U postgres -d gis
CREATE EXTENSION hstore;

Import went without errors.

Then I used this 2 queries to extract lat lon coords and names of suburb and cities:

SELECT name, st_astext(st_transform(way, 4326)) FROM planet_osm_point WHERE place='city' OR place='town' ORDER BY name;

Example:

st_astext,name
POINT(12.3669594982785 50.1246967948147),Aleje-Zátiší
POINT(12.7287439982281 50.4273214948056),Altstadt
POINT(15.5997642978285 49.467412494836),Antonínův Důl

It's all done well, but I got only names on Czech language. How to get the same list but with English names of suburb and cities?

postgres postgis osm2pgsql

One Answer:

You have not imported the English names into your database.

You will need to either modify the "style file" that comes with osm2pgsql to load the name:en tag into the database, or use the --hstore flag on import which will create an additional column called "tags" that contains the additional data.

Then you can select "name:en" respectively tags->'name:en' instead of name and work with that.

Akuli, please also keep in mind that not all places you are looking for will have a name:en tag (actually, I believe only few will have). Depending on your use case you may need to have fallback to the name tag. Another way would be to check if there is a wikidata tag and look up an English name on Wikidata (outside your existing workflow).
