Hello Kevin,

Have you gotten a chance to validate the coastlines of the Great Lakes during 
the last weekend?
You’re the only one who responded to my “help” request….

Thanks,

Michel

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….



Someone probably broke the coastline again. It's easy to goof when editing the 
lake shore.
I don't have time to look into it right now, I can try on the weekend if 
someone else doesn't fix it first.
(And, I confess, I've broken the lake shore of Lake Ontario at least once.
I fixed it promptly once I realized the problem.)
