Hi everyone,
I am relatively new to using OSM data and osm2pgsql and have been doing some testing during the last few weeks. I am using the following command lines and I am pretty not sure, if I am doing it in the right way: osm2pgsql --verbose --create --slim --cache 4096 --prefix planet_osm --database osmtest --username gis --host localhost --hstore --extra-attributes --style /gis/maps/planet/style/default.style --number-processes 4 --bbox 7.85,51.50,11.32,55.06 schleswig-holstein-latest.osm.pbf osm2pgsql --verbose --append --slim --cache 4096 --prefix planet_osm --database osmtest --username gis --host localhost --hstore --extra-attributes --style /gis/maps/planet/style/default.style --number-processes 4 --bbox 7.85,51.50,11.32,55.06 hamburg-latest.osm.pbf osm2pgsql --verbose --append --slim --cache 4096 --prefix planet_osm --database osmtest --username gis --host localhost --hstore --extra-attributes --style /gis/maps/planet/style/default.style --number-processes 4 --bbox 7.85,51.50,11.32,55.06 niedersachsen-latest.osm.pbf The result should be a "merging" of 3 osm data files, the first line is doing a good job , but during the second line there is an error: Reading in file: hamburg-latest.osm.pbf Processing: Node(2156k 113.5k/s) Way(405k 27.00k/s) Relation(0 0.00/s)COPY_END for COPY planet_osm_ways FROM STDIN; failed: ERROR: duplicate key value violates unique constraint "planet_osm_ways_pkey" DETAIL: Key (id)=(3075476) already exists. CONTEXT: COPY planet_osm_ways, line 193 I would be glad if anyone could tell me, what I have missed and what I am doing wring here? Thanks a lot, Stefan
