Lake: a natural or semi-natural body of relatively still fresh or salt water, localized in a basin that is surrounded by land. Artificially created lakes should instead be tagged as water=basin
, water=reservoir
, or water=pond
.
How to map
Draw a closed way to form an area. Add water=lake
+ natural=water
.
Tags used in combination
name=*
- The officially designated name.intermittent=yes
- Intermittent lakes (which disappear seasonally).salt=yes
- For salt lakes.
Islands
Lakes with one or more islands in them should be mapped as multipolygons.
First, map the island(s).
- for each island, draw the outline
of the island by tracing its shoreline
- add
place=island
or if it is very smallplace=islet
- optional
landuse=*
can be added. For example, if the island is wooded, addlanduse=forest
ornatural=wood
. - if the island has a
name=*
of its own, add it here too
Next, map the lake outline.
- draw a closed way
following the lake's shoreline
- do not add any tags to this way – the lake's tags will instead be put on the parent relation
Finally, create a type=multipolygon
relation.
- All tags, including
natural=water
andwater=lake
should be on the relation. - Add the lake outline as a member with role outer
- add the island(s) as members with role inner
