[OSM-dev] Workflow for bulk upload of GPX files

[marc marc]

if you want to add yourself all these missing ways in osm,
a simpler workflow :
give a part to each one
load the gpx trace with the editor of your choice
simplify and connect it to the concerned ways, add tags
upload the new ways into osm.
some will say you may send the trace too.
once finished, delete the trace of your computer
or move it to a "done" directory

and so on with the next trace until you finish your part :)
