Original data is in shapefile format. I've put the original files in
osm format to make it easier to open in JOSM. I can give you access to
the shapefiles if you need so.

The original files are given to me directly by the WRI staff.

It's clear that ALL forestry tracks are unpaved in Africa, specially
in that area. Even most of trunk national roads are unpaved, and
sometimes impassable during part of the year.

All these highways are tracks, as they are used for forestry, not for
connection purposes. If they were any connecting way, it would be
corrected. Remember that this import will be manual, and go through a
validation process. It has more of mapping than importing.

I suppose so. Most of the tracks just lead nowhere except for logging
purposes. Even if it was allowed to drive on them, it would be useless
except for staff involved in logging activities. The same applies to
the few agricultural tracks.

Good point. I will add this to the workflow.

Cheers,

Rafael.
