Call of the Wild I Mapping good dogs in the Yukon

" summary

Volunteers build live tracking for the 320 km Percy DeWolfe Mail Race using Spot GPS units and open source web mapping, starting with manual overnight position updates then moving to an automated API harvest and mapping pipeline. Common failures include the units’ 24-hour reset, trackers accidentally turned off, falling off sleds, and time zone/border and shifting river trails that break route stats. The system works well for fans but requires hands-on troubleshooting each race.
