A list of available tile servers for OpenStreeMap can be found here. More tile servers and URLs can also be found https://www.xyht.com/spatial-itgis/using-openstreetmap-basemaps-qgis-3-0/.

• Set “CacheId” to “osm_map”
• Keep profile to “spherical-mercator”
• Set “Gamma correction” to “0.3”

The list of tile map server on https://wiki.openstreetmap.org/wiki/Tile_servers has also some “useful” overlay map layers (e.g. transport or sea markers).

• Create a XYZ image layer and set the URL to one listed in the table (e.g. http://tile.memomaps.de/tilegen/${z}/${x}/${y}.pn)
• Keep profile to “spherical-mercator”
• If the layer appears too bright, then decrease the gamma correction value.

• Add a new layer to the configuration under the group “Global Imagery”
• Set type to “Imagery”
• Select driver “XYZ”
• set URL to http://tile.thunderforest.com/cycle/${z}/${x}/${y}.png
• Keep profile to “spherical-mercator”
• Set “CacheId” to “osm_cycle”
• Set “Gamma correction” to “0.3”

• Add a new layer to the configuration under the group “Global Imagery”
