[Talk-us] Great Lakes missing after osmosis update (diffs installation)

[Pilon, Michel (SSC/SPC)]

Hello all,

I am in the process of putting in place a local OSM server.

Last Thursday September 21st I populated my PostGIS database using the following command:

osm2pgsql --create --slim --flat-nodes /data/osm/pgload/flat_nodes.bin \
         -C 27000 --number-processes 8 --hstore \
         --style /data/osm/openstreetmap-carto-3.2.0/openstreetmap-carto.style \
         --multi-geometry /data/osm/new_planet-latest.osm.pbf

Once done I verified the slippymap and I can see correctly all the Canadian/US Great Lakes.

So I applied the daily updates on the data using osmosis (daily diff).   Once completed, everything looks good EXCEPT that there is no more water on Great Lakes except Lac Érié and Ontario for ALL ZOOM LEVELS. Superior, Michigan and Huron Lakes just disappeared!

For the update process, I am using /usr/bin/openstreetmap-tiles-update-expire with the followng options for osm2pgsql command:
               OSM2PGSQL_OPTIONS="--number-processes 8 --hstore -C 27000 --style /data/osm/openstreetmap-carto-3.2.0/openstreetmap-carto.style --multi-geometry"

I am using mapnik with openstreetmap-carto stylesheets.

I am really stuck and need help as I tried it 3 times, always with the result of Lakes disappearing for all zoom levels... :(

Any ideas???

Thanks in advanced for your very appreciated help....

Michel
