Données incorrectes par osm2pgsql pour multipolygones

Question

J'essaie de convertir les données OSM en Europe vers ma base de données postgis et je constate que certains pays comme la Grèce ou la Russie sont importés de manière incorrecte.

Il semble que cela ne prenne qu'une partie de leurs géométries. Par exemple, il n'y a que deux îles séparées pour la Grèce dans ma base de données après l'importation osm2pgsql.

C'est très étrange. J'ai essayé d'utiliser des arguments différents et j'ai obtenu le même résultat. J'utilise la dernière version osm2pgsql de SVN 0,69-23858 et le fichier OSM de Geofabrik.

osm2pgsql -d osm2pgsql_greece -S ~/osm/default.style -U postgres -W -H localhost -G --slim ~/osm/greece.osm 

SELECT ST_AsText(way) FROM planet_osm_polygon p WHERE p.admin_level = '2'

Answer 1

Je n'ai pas grand-chose à suggérer si ce n'est: Avez-vous essayé les autres formats fournis par OSM? Par exemple. utiliser leurs fichiers de formes et essayer de les importer avec sph2postgresql? (Je aussi ici ogr2ogr pourrait le faire).

Vous perdrez probablement une grande partie de l'information descriptive, mais ce pourrait être un guide pour savoir si les formes manquantes sont vraiment là?
