[[Image(source:trunk/images/converttoosm.png)]]

Creates a new OSM Data Layer comprising a [[Image(source:trunk/images/data/way.png)]] [Concepts/Object#Ways way] for each track in the GPX data, consisting of a [[Image(source:trunk/images/data/node.png)]] [Concepts/Object#Nodes node] in sequence for each track point.

This is very much only a starting point. You will need to split the ways up, connect them with correct topology, move nodes around, thin them out, tag them and so on. **Never upload raw converted  ways! **

When converting a [wiki:Help/Dialog/LayerList#Layertypes Marker Layer] the following "tags" of the marker will be converted to osm tags:
||= marker tag =||= osm tag =||
|| name || name ||
|| desc || description ||
|| cmt || note ||
|| sym || gpxicon ||

You can adjust or enhance this list by modifying the key `gpx.to-osm-mapping` in the [wiki:Help/Preferences/Advanced Advanced Preferences]. The key gpxicon is intended for custom icon display within JOSM, so make sure to not upload any keys which should not be part of the osm database. (See also #13717, the implementation of this feature.)
