Four beats, four backgrounds: atlas, satellite imagery, a remote raster tile layer, and 3D terrain.
The default paper-and-ink basemap. Data layers sit in the top slot above basemap labels.
Basemap switched per beat to imagery; the data layers survive the style change.
An XYZ raster layer (OpenTopoMap) added as a project layer on a blank basemap. Any tile server works.
Terrain enabled on this beat with 1.6× exaggeration, pitch 62°, bearing 35°.
