Mapping question about something I’m seeing in Gaia GPS in the “Outdoors” layer.
The map shows a purple line that follows some roads and trails. If I zoom in the line is shown as purple dots. These purple dots indicate a route?
I finally found a label for this purple line, but so far my internet searches find nothing about this “Cross Snohomish County Hike & Bike Route.”
Clearly this route exists in this map. Where did it come from and how can I learn more about it?
@wplate No idea where that trail data originated.
Below is a GISsurfer link that displays data straight from OSM. The map opens centered just south of the town of Snohomish. That trail/route/whatever is not in the OSM data.
Snohomish county has 2 public ArcGIS servers on the list I curate. But those servers do not seem to have any of the county trail data. And the county recreation page does not seem to say anything relevant.
That trail also does not show up in a GIS trail layer the state maintains.
Looks like you will just have to go there, follow it and see whats what. Gonna be super nice weather next weekend. 🌞 😎

@mappingsupport Thank you for the awesome and thoughtful reply! I looked further and learned that the “Outdoors" Gaia layer is the same as Caltopo’s TF Outdoors, and Caltopo’s help taught me that TF was Thunderforest. I emailed TF and they replied and pointed to where in OpenStreetMap this route originated! https://www.openstreetmap.org/relation/16917063
The history page tells me who originally created the route and who has recently edited it.
I’m super excited! Thanks for replying and helping me out!
