Stamen Watercolor tiles should request JPG not PNG, and needs to update to a new Stadia Maps URL
The Stamen Watercolor basemap layer is no longer working. That is because the URL template here requests png
tiles, but Watercolor only supports jpg
.
Previously, Stamen's code was very permissive and would return a jpg
tile when a png
was requested, but now you have to correctly specify jpg
to get tiles.
Additionally, Stamen is in the process of migrating our tile hosting over to Stadia Maps, so the old Fastly URLs for Watercolor are changing anyway.
Instead of using https://stamen-tiles-{s}.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.jpg
, you should now use the URL https://tiles.stadiamaps.com/tiles/stamen_watercolor/{z}/{x}/{y}.jpg
.
Also note that if GoGoCarto doesn't have an account on Stadia, you may need to create one. But I see that GoGoCarto already supports other Stadia basemaps, so probably you are already setup there.
For more information, see this migration guide: https://docs.stadiamaps.com/guides/migrating-from-stamen-map-tiles/
And for the corresponding issue that your user raised on Stamen's github, see: https://github.com/stamen/maps.stamen.com/issues/208
Thank you for including Watercolor in your excellent mapping tool!
