Former riverbed
Status: Draft (under way)
Proposed by: Lzhl
Tagging: waterway=former_riverbed
Applies to: way, area
Definition: For old riverbed without flow
Rendered as: For area as lake, for way as river
Drafted on: 2009-11-12

Rationale

At present users draw former riverbed as area tagged with natural=water when riverbed with flow (not wide river) draw as way tagged with waterway=river. But in fact these objects (former riverbed and riverbed with flow of not wide river) have exactly the same forms and characteristics exept flow. I think that drawing these objects with one primitives will be more correctly.

For example river Vetluga which have a lot of long and not wide former riverbeds.

Rendering

Rendering these objects same lakes (area) and rivers (way).
