Hi,
I'm currently experimenting with Lua tag transformations when importing
data with osm2pgsql and trying to remove members of type=route relations
(public transport routes) that have the role platform from
planet_osm_line. The problem I'm trying to avoid can be seen here:
https://www.openstreetmap.org/#map=18/48.19117/16.34794&layers=T
(platforms coloured like routes)
I thought that when I set membersuperseded = 1 for the corresponding
relation members in filter_tags_relation_member this would work, but
apparently it isn't.
Here is the relevant part of the function:
function filter_tags_relation_member (keyvalues, keyvaluemembers, roles,
membercount)
...
membersuperseded = {}
for i = 1, membercount do
membersuperseded[i] = 0
end
...
if (type == "route") then
linestring = 1
for i = 1,membercount do
if (roles[i] == "platform") then
membersuperseded[i] = 1
end
end
end
...
end
What am I doing wrong? It is possible that I'm thinking in totally wrong
directions, any hint is appreciated.
Best, nebulon42
