7b21354a8a avoid multiple centroid computations 2024-11-03 22:06:36 +01:00
Sarah Hoffmann
ad50016c49 use line interpolation to create centroid for lines 
ST_PointOnSurface always returns one of the vertices of a line.
This means that a two-point line will have the centroid at
one of the ends, which is less then ideal.

054efc8311 ensure consistent country assignments 
When OSM data has areas with overlapping countries, use the country
assignments from the pre-defined country grid for tie-breaking.
If that fails, fall back to the country with the smaller partition
number.

350bb0e1cd restrict invalidation of child objects on large street features 
When streets become very large, it is more likely a mapping error.
So ignore such changes.

77631f90fd reindex postcodes that loose their parents 
When the parent place of a postcode is deleted, it needs to
be reindexed to get a new parent. Otherwise displaying of
results is broken.

any ither housenumbers with missing address terms.

62b7670e0c for postcodes use rank_search as base rank for finding addresses 
The rank_address reflects the position in the address which is
usually lower than what one would expect for a postcode area.

56201feb28 simplify very large polygons non used in addresses 
Polygons with rank_address = 0 are only used in search and (rarely)
for reverse lookup. Geometries do not need to be precise for that
because topology does not matter. OSM has some very large polygons
of natural features with sizes of more than 10MB. Simplify these
polygons to keep the database and indexes smaller.

4c19762e33 extratags should become null when empty 
Removing the artifical entries in the extratags may lead to
an empty hstore. Set it to null in that case.

81eed0680c recreate word table when refreshing counts 
The counting touches a large part of the word table, leaving
bloated tables and indexes. Thus recreate the table instead and
swap it in.

a more logical structure than separate arrays. Avoid JSON dicts
because of their verboseness.

c5f5ab5363 be more strict about removal from place_to_be_deleted 
If the type of a place is changed and then the same insert issued
again, the old data will effectively remain in the table.

7c79b07817 fix parameter use for ST_Project 
Before postgis 3.4 ST_Project required a geography as input and seemed
to have implicitly converted to geography. Since 3.4 geometry input
is supported but leads to a completely different result.

645ea5a057 use information from tokenizer to determine street vs. place address 
So far the SQL logic used the information from the address field
to determine if an address is attached to a street or place.
This changes the logic to use the information provided in the
token_info. This allows sanitizers to enforce a certain parenting
without changing the visible address information.

60c1301fca fix a number of corner cases with interpolation splitting 
Snapping a line to a point before splitting was meant to ensure
that the split point is really on the line. However, ST_Snap() does
not always behave well for this case. It may shorten the interpolation
line in some cases with the result that two points housenumbers
suddenly fall on the same point. It might also shorten the line down
to a single point which then makes ST_Split() crash.

Switch to a combination of ST_LineLocatePoint and ST_LineSubString
instead, which guarantees to keep the original geometry. Explicitly
handle the corner cases, where the split point falls on the beginning
or end of the line.

8ed096f938 speed up reverse lookup of place nodes 
Add a special index that contains the place nodes buffered by their
respective area according to their search rank. This replaces the
maximum area search for place nodes and reduces drastically the number
of place nodes that need to be retrieved.

3f38091421 split query that deletes old objects from placex 
placex only has partial indexes over OSM types, so the OSM type
needs to be hardcoded to ensure these indexes are used.
