Unnamed nodes are not exported as GPX waypoints

[brycenesbitt]

1) Load a few thousand points into a data layer. For example "Open location" with:
​http://open.mapquestapi.com/xapi/api/0.6/node[amenity=pub]

2) Export to gpx or compressed gpx.

3) Observe your export, silently, has 4260 points.

4) Now delete points until you are at 3000 points.

5) Export again.

6) Observe the gpx file has 4260 points.

Works for me with latest version of JOSM.
Can you please attach your status report, and the file you have at each step ? Thanks.

[Don-vip]

up ?

[brycenesbitt]

1) From File->Open Location load ​http://open.mapquestapi.com/xapi/api/0.6/node[amenity=drinking_water]

and verify it has 34,00 nodes.

2) File->Export to GPS to "test.gpx"
3) grep "wpt lat" /home/bnesbitt/temp/text.gpx | wc

4260 12780 175375

4) Delete half the world's water fountains, and do it again, and you get 4260 points again. Lon? Long? Longitude? Position-X?

It looks like GPX export may be skipping the ones without a "name=" tag?

Separately: It would be nice if the CSV import documented on screen what column names it wants.

[brycenesbitt]

Verified. The GPX export requires a name=* tag, or it silently leaves out the node.
Instead how about creating an empty <name> in the GPX, or <name>null</name>?

Also: Importing the same gpx file results in a non-editable layer.

ok thanks :)

Looks intentional in r4046.

Dirk, do you think we should save unnamed nodes too ?

[brycenesbitt]

If intentional, it would help if it said so (4600 or 35000 nodes exported) or (3999 of 4000 nodes exported).
It is too easy not to notice you're missing data if the numbers are close.

[stoecker]

If I understand that right named nodes are exported as waypoints (and trackpoints), unnamed only as trackpoints. Seems correct to me.

If they aren't exported as trackpoints or waypoints, then something is wrong I'd assume.

[brycenesbitt]

There are no <trk> or <rte> points in the gpx file from above.
The principle of least surprise I think is to output them all as <wpt>, even if they have no name=tag.

So it is at least an implementation bug, if not a design issue.

[stoecker]

Probably only line-points are output as trackpoint? In this case we'd need to add output of unnamed single points as unnamed waypoint as well.

In 6015/josm:

fix #8788 - include unnamed nodes as GPX waypoints during GPX export
