The previous behaviour was a left-over from a former version
where such POIs parented to the street. Now that they parent to
places, it should be included.
get_addressdata() now also checks if the place itself has entries
in the place_addressline table and merges them into the results.
Also restrict checking for address tag places to cases where the
name cannot be found in the parent's address search terms. Looking
up all address tags is just too slow.
While previously the content of addr:* tags was only added
to the list of address search keywords, we now really look up
the matching place. This has the advantage that we pull in all
potential translations from the place, just like all the other
address terms that are looked up by neighbourhood search.
If no place can be found for a given name, the content of the
addr:* tag is still added to the search keywords as before.
Go back to using centroid when determining if one admin level
is within another. There are cases where boundaries are slightly
misaligned due to mapping errors (not using the same ways in the
relations).
Only declare boundaries the same when they have the same wikidata
tag _and_ have exactly the same geometry. This works around tagging
errors with the wikidata tag, which happen because of automated
edits to the wikidata tag.
The Polish community maps admin boundaries that span multiple
levels by duplicating the boundary relations. Detect this situation
by looking out for matching wikidata tags. The higher ranked
duplicates are then thrown out from the address pool by setting
their address rank to 0.
Now that the containment check uses ST_Relate, we need to add
a separate bbox contains check to ensure that Postgis does the
efficient check first. Note that we still cannot get rid of the
overlap(&&) check because then Postgis will use the wrong indexes.
The new address computation assumes that the centroid is inside
the area. Therefore we cannot use the centroid function. Use the
pre-computed centroid instead which has already been corrected to
be inside the area.
Also demote the address rank of an admin boundary when there
is a place area of higher rank that completely contains the
area. This catches the case where city boundaries do not exactly
align with administrative units (see for example Moscow).
This is a complete rewrite of the selection of address parts to
be inserted into the place_addressline table.
The new algorithm selects for each rank:
* the boundary overlapping with the addressee and contained
in the already selected boundaries of lower rank, or failing that
* the place node closest to the addressee that is contained in
the already selected boundaries and in the influence radius
of already selected place nodes of lower rank
Place nodes that are not contained in already selected boundaries
of lower rank are completely thrown away. All other candidates are
added as non-address parts.
If a place node of city rank and above finds itself in an
administrative boundary of the same address rank, then
increase the address rank by 2. This catches the rather
frequent case where city suburbs are tagged for historical
reasons as towns or villages.
The latest version of osm2pgsql no longer creates indexes on
the members of planet_osm_rels. So we do that ourselves.
Given that we only need to access associated street relations,
the index can become quite a bit smaller.
Using both is slightly problematic because they have different
ways to use the index. Newer versions of Postgis exhibit a
query planner issue when both functions appear together.
As ST_Intersects includes ST_Covers, simply remove the latter.
We can't use getNearFeatures() to determine the parent of a
place with an unlisted addr:place because this function
returns place nodes that are potentially outside the area
of interest. Doing the complete address computation is too
expensive, so simply use the area with the largest rank that
contains the feature instead.
When a POI has no addr:street but an addr:place that is not
contained in the name list of the parent place, then remember
this situation and merge the content of addr:place into the
address output.
We don't need to care about translations in this case because
it is obvious that no object with translations exists if the
parent isn't the object named in addr:place.
These are used to mark large paved areas. Sometimes they exists
together with named regular streets. In such cases the unnamed
area may overshadow the actual street when computing the address
parent. As unnamed highways are not very useful anyway, we
simply remove them from the database.
If an addr:place is given but no addr:street tag, then bind
the rank 30 object always to a <=25 object, even when there
is none found with the same name.
When a place of rank 30 has addr tags that are not covered by the
search terms of the parent, add a separate entry for the POI in
the search_name table that includes the addr tags. We can only
do that with named places. For POIs without a name the housenumber
is used as name. If that is not available either, searching still
won't work.
Colons are used as a delimiter in tiger:left and tiger:right tags
when multiple postcodes are given. Ignore those. This was already
done in the postcode update script. This changes just makes the
two places consistent where postcodes are added.
place=postcode places are artificial places that collect addr:postcode
points for aggration. They should neither show up in the address nor
be searchable. That means that there is no need to index them at all.
Only let boundary=postal_code through which define correct areas for
postcodes.
Boundaries shound derive the address part type from the
linked place if possible. This was already implemented
for the address objects but not for the address information
from the address itself.
Fixes#1949.
It may happen that two different postcodes normalize to exactly
the same token. In that case we still need two different entries
in the word table. Token lookup will then make sure that the correct
one is choosen.
Fixes#1953.
Further reduce the size from which on POIs are no longer bound
to streets but only to larger objects. The point of reference,
of what a largest POI could be that is still bound is JFK airport.
Squares are now addressable (on address level 25) and thus can
be attached to a house number via addr:place. Needed to increase
the rank range for matching up addr:place to 25.
