I'm trying to reverse geocode some points using an OSM import into PostGIS. I imported the OSM data (for Denmark so all addresses should be avaialable) into PostGIS using osm2pgsql enabling "addr:street" and "addr:housenumber". All the addresses should now be in the
My points table that I want to reverse geocode is created using
update tower set the_geom = st_transform(st_setsrid(st_makepoint(xcoord,
When trying to use the following code I get some very weird results where as far as I can see the addresses I end up with are either random but still within the general area or maybe displaced by up to a few km:
update tower set nearest_number = t."addr:housenumber", nearest_street = t."addr:street"
select "addr:housenumber", "addr:street", pk from planet_osm_point, tower
where st_dwithin(st_transform(planet_osm_point.way, 4326), tower.the_geom, 0.01)
order by st_transform(planet_osm_point.way,4326) <-> tower.the_geom ASC
In the attached image I have labeled the points with the result of the reverse geocoding, and as an example I have highligthed a point which has gotten an address that is located longer to the north, somewhat beyond the boundary. Anyone have any ideas as to what I'm doing wrong?
