Avoid joining highway=* to landuse=*

[mkoniecz]

What steps will reproduce the problem?

1. Start making highway=* way
2. Attempt to join it to existing highway=* located near landuse=* boundary

What is the expected result?

Crossing of highway=* ways is created - and landuse is not affected

• in pseudocode:

what_will_be_joined(position, currently_edited_way)

candidates = all_nearby_ways(position)
if !currently_edited_way.matches("highway = *")

return

if.candidates.filter("highway = *") != []

return candidates.filter(landuse == null)

What happens instead?

Crossing of highway=* ways and landuse=* way is created

• in pseudocode:

what_will_be_joined(position)

return all_nearby_ways(position)

Please provide any additional information below. Attach a screenshot if possible.

Use the filter feature to filter out unwanted elements.

[mkoniecz]

@stoecker But for editing that involves modifying various kinds of elements it would require constant enabling/disabling filters. Even constant zooming in/out is better.

[stoecker]

The typical case for what you request is to filter out landuse when you work on roads. What you request is a working mode, which is not shared by all users and thus cannot be implemented as a generic rule. I myself e.g. prefer joining landuse borders and roads when useful.

A filter can be enabled and disabled extremely fast and what you request is exactly the use case they have been developed for.
