onlineBasemapProvider

Online basemap tile provider used as fallback when a property has no per-property MBTiles (mapTilesFilerId is null/empty) or only a sparse one.

Default: CARTO_CDN, which since 26.10.4 draws the Mapsted "Vivid" basemap, in the same colours as maps.mapsted.com, from OpenFreeMap vector tiles (the constant keeps its old name for compatibility).

For OPENMAPTILES_SELF_HOSTED also set onlineBasemapVectorTileUrl and onlineBasemapStyleAsset. For CUSTOM_RASTER set onlineBasemapRasterTileUrl. A provider that is not configured falls back to the default Mapsted basemap.
