Before my trip I had high hopes for distributing cheap GPS units to public transport workers and try to get some decent traces starring out from Kaduna. Sadly that didn't happen mainly due to lack of time, I was actually working there, and while mapping seems to absorb nearly all my free time, it doesn't pay the bills!
So I had about 20 days of traces that I have compiled into two sets of GPX traces with large amounts of clutter removed using GPXEdit via JOSM.
I understand some express concern over editing of traces, but when you leave a garmin HCX on overnight in your hotel room ( several nights after JOSM editing ) and it finds lock, you end up with a rather large GPX traces pointing roughly to your room ( on what looks like a drunken walk ) which is of absolutely no value to anyone!
So 23 Mb down to 5.5Mb. At the end of the day, if users are competent, to edit the public Map directly, they are probably okay to remove excess clutter from their private GPX traces, and uploading 'GPX noise' I would argue is a distraction to future editors, not an asset.
Thanks for all the comments from everyone and assistance while I was there, couldn't answer personally as the internet was dreadful.
Now have to schedule my next trip!
