- Add wp b/n P1018 and R104 for Tiznit bypass
- Check route in Guelmim, OSM and GM routings do differ, wikipedia confirms GM+HB, no GSV, no mapillary
- Add wp for future bypass west of Guelmim?
- Is N1 now routed via the Tan-Tan bypass? Minimum add wps for both end! OSM+wikipedia indicate both routings, GM (still) through the town, no mapillary, a Nov 2022 "GSV pic" does not show any number
- Update concurrent TAH1 too
