Problem
pgr_nodenetwork misses nodes on very long ferry lines imported from OSM.
To Reproduce
Load the table public.lines from the sql in the Sample Data section.
Execute
select pgr_nodenetwork('public.lines', 0.0001, id := 'way_id', the_geom := 'geom');
select pgr_createtopology('public.lines_noded', 0.0001, the_geom := 'geom', id := 'id');
Expectation
All points where the lines overlap should be noded. However, some are missing.
Multiple re-runs give the same missing nodes, so the failure seems to be at least stable over time.
With the results from this sample data, one is missing (in the middle, above the two overlapping nodes):
Sample Data
create table lines
(
way_id bigint not null,
tags hstore,
geom geometry(LineString, 3857)
);
alter table lines
owner to postgres;
create index lines_geom_idx
on lines using gist (geom);
create index lines_way_id_idx
on lines (way_id);
