Planted date unification
Proposal status: Draft (under way)
Proposed by: UsefulRabbit
Draft started: 2024-07-13

Proposal

Establish that start_date=* is the primary way of tagging the date when vegetation was planted in its current location (or otherwise came into existence).

Deprecate the following tags, encouraging usage of start_date=* instead as a drop-in replacement:

Deprecate the planted:age=* tag, encouraging concrete years/months/days with start_date=*, and the tree's size with age=*.

Further consensus is needed on age=*.

Rationale

Currently, we use a variety of tags to indicate when a plant was planted. This is undesirable for people who want to query or display that information in a unified manner.

start_date=* is the most-used tag for indicating planted dates on OSM (427,464 at the time of writing) and has applications outside of mapping plants, so I selected it to be the primary tag.

Statistics for tags that will be deprecated are linked below.

Tag Count
planted_date=*
planted=*
year_planted=*
date:planted=*
date_planted=*
plant_year=*
plant:age=*

Tagging

Use the established conventions used with start_date=*.

Examples

Here are a handful of examples correctly using start_date=* for planted dates:
