[OSM-talk] Overlapping ways

[Rob Nickerson]

Hi,

I used the layer tag, but not bridge (as its a carpark not a bridge) but
because the way shares nodes with the way one layer down, it seems to be
flagged as duplicate and deleted by other mappers.

For example, in the following car park, cars enter up the ramp on to level
1. There is a rectangular service road (parking aisle) on this level, which
I have tagged with "layer=1". Cars can the go down the ramp to layer 0.
Although I can't see this on Bing to fill in the parking aisle, I do know
that part of this runs underneath the level 1 parking aisle in order to get
to the car parks ground exit.

As you will see, because the layer 0 "exit" way runs directly under my
rectangular level 1 parking aisle, it appears to be flagged as a "duplicate
way" in one of the fixer tools. As such someone has removed part of the
rectangular "layer=1" way, leaving just a horse shoe (which is incorrect):

Am I doing something wrong? Is the fixer tool flagging something up
incorrectly?

Regards,
Rob
