Import TIGER data into a temporary table first that later replaces
the current location_property_tiger table. This way index creation
on the table can be delayed until after the import which should
speed up the import and result in significantly smaller indexes.
Also removed index on parent_place_id as it is covered by
idx_location_property_tiger_housenumber_parent_place_id.
Changes slightly the logic which decides if a guessed places
(i.e. a place node) is included in an address: it will be
part of the address only if it is inside the next lower
available boundary. This fixes problematic cases where
neighbouring entities have additional admin levels.
This solves a bug with updating large invalid geometries. These
geometries have an entry in place but not in placex. Thus, place_insert
tries to delete the place entry and reinsert it on update. Deletion would
fail because self-intersecting polygons still have an area and large
areas are not deleted.
function changes:
-----------------
Move to ST_PointOnSurface from ST_Centroid in various places to avoid looking up a point outside the polygon
Move to ST_Covers from ST_Contains to include points on admin boundaries
Re-order preference for get_country_code now our data is better. country_osm_grid is now the preffered source.
Fix code to calculate country code in placex_insert, rank_search test was too early
Add extra field to placex 'calculated_country_code' to improve structure of code
Move split_geometery function out of add_location into its own function
Rewrite split_geometery to be more efficient.
Change place_insert to do more updates and less delete/inserts (delete is slow)
Include wikipedia links in details.php ouput
Cleanup no longer used geometry validation (adding overhead)
Include debug statements in function.sql (--DEBUG: ) and add flag to setup.php to turn them on
setup.php:
----------
add flag --disable-token-precalc to speed up debuging
add flag --index-noanalyse to disable analysising DB at rank 4 and 26 (previously removed, but on my local DB it seems to be required)
add flag --enable-diff-updates (modifier to --create-functions) to turn on the code required for diff updates without having to modify functions.sql
add flag --enable-debug-statements (modifier to --create-functions) to turn on debug warning statements
update.php:
-----------
added flag --no-index to import osmosis changes without indexing them
extend the hack to allow import of JOSM generated osm files
country_grid.sql - reference copy of the sql used to generate the country_osm_grid table, needs cleanup
Needs tweaking on the osm2pgsql side, too: the osmid column
needs to have the same format as in osm2pgsql. That means
that the changes are still not compatible with existing installations.
label relation member
admin_center, admin_centre relation member (with same name)
exact name, search_rank and location match
Adding this requires a new column and index:
SELECT AddGeometryColumn('placex', 'centroid', 4326, 'GEOMETRY', 2);
CREATE INDEX idx_placex_linked_place_id ON placex USING BTREE (linked_place_id);
