I have a shape file with feature class polygon and want to convert them into an osm file. I've verified the polygons by several transformers in workspace. The result is always an osm file with lines instead of polygons (FME Inspector)???
Question
How can i export polygons from shape to osm?

Hi @happymapper,
According the FME Readers and Writers Reference, the geometry polygon is enable in OSM.
The documentation Documentation - OSM

,
the problem was caused by the viewer in fme inspector which interprated the polygons as lines.

Hi @happymapper and @danilo_fme
The OSM writer is working as expected:
See https://wiki.openstreetmap.org/wiki/Area/The_Future_of_Areas:
"OpenStreetMap does not have a native Area (or polygon) data primitive and areas are currently modeled using Ways which are also used to describe Polylines.
Not all closed polylines are areas, as this varies based on which other tags are present. A closed way tagged highway=pedestrian is considered to be a circular path unless it has a area=yes tag which turns it into a pedestrianised area, however a closed way tagged with leisure=park is assumed to be an area. Areas can also be described using multiple ways as members of a relation:multipolygon. It is possible within the editors to create parks which are not closed even though these won't normally render unless they are included in a multipolygon. Anyone wishing to tag areas or use areas therefore needs to always check on the default usage of closed ways."
Also see:
https://wiki.openstreetmap.org/wiki/Key:building
Adding a "building" attribute with "museum" or any other value, to the "Barry_Art_Museum" feature type will result in ta "building" tag in the osm output:
<way id="...">
...
<tag k="building" v="museum"/>
</way>
If the output is read back by the OSM reader then it will interpret this particular way, whose 1st and last coordinate equal as an area.
