[mkgmap-dev] Dealing with JOSM exports

Fri Nov 22 14:03:36 GMT 2024

Hi Felix,

I think the messages from osmconvert are correct.  -324214 is less than  -324213, so the nodes are not in the expected order.

Betreff: [mkgmap-dev] Dealing with JOSM exports

Hi,

for some special application I'm parsing gpx-files to osm-files, identical to importing the .gpx into JOSM, convert them to datalayers and finally export to .osm.
These files are then processed by splitter to .o5m.
I'd like to add a timestamp to the .o5m using "osmconvert --timestamp" next.
While that normally works for split-files based on OSM data, for the above files osmconvert allways throws 6 warnings like

osmconvert Warning: wrong sequence at node -324213
osmconvert Warning: next object is node -324214
osmconvert Warning: wrong sequence at node -324214
osmconvert Warning: next object is node -324215
osmconvert Warning: wrong sequence at node -324215
osmconvert Warning: next object is node -324216

I guess, osmconvert is expecting ordered increasing positive IDs only.
Iirc the decreasing negative IDs are correct here nevertheless, implemented long ago to indicate dealing with non OSM objects.
mkgmap seems to work perfectly fine on such split-files.

Did I miss any means to avoid these warnings and have the timestamp added other than converting the IDs to positive?

Thanks
