| Suffix :start and :end | |

| Proposal status: | Abandoned (inactive) |
| Proposed by: | imagic |
| Applies to: | 
|
| Definition: | The suffixes :start and :end might be used to specify a property at the beginning or the end of an OSM way. |
| Draft started: | 2015-01-15 |
The suffixes :start and :end might be used to specify a property at the beginning or the end of an OSM way.
Rationale
Sometimes the property of a way gradually changes from one value to another. The proposed suffixes allow us to specify the value of such property at the start and end of a OSM way.
Tagging
If the value of a property at the end of an OSM way is different than the value at the beginning, use the relevant key and add the suffix :start to indicate the value at the beginning of the OSM way, and use the relevant key now with the suffix :end to indicate the value at the end of the OSM way.
Examples
| Tags | Description |
|---|---|
| kerb:start=lowered kerb:end=raised |
The kerb of a sidewalk is lowered at the beginning of the OSM way and raised at the end. |
| placement:start=right_of:1 placement:end=right_of:2 |
The node at the beginning of the OSM way is drawn at the right side of the first lane, while the node at the end of the OSM way is drawn at the right side of the second lane. |
| width:start=10 width:lanes:forward:start=3|2 width:lanes:backward:start=3.5|1.5 |
The width of the carriageway at the beginning of the OSM way is 10 metres. Here the lanes leading in forward direction are 3 and 2 metres wide and the lanes in backward direction are 3.5 and 1.5 metres wide. Attention: the suffixes :start resp. :end always refer to the beginning resp. end of an OSM way, even if combined with the :backward suffix! |
Current usage
kerb:end=*
