The question of "why PMTiles" was raised in a previous comment. I think a nice answer lies in this article Open Source Mapping for News: Reuters. |

I open this PR as per this issue and this discussion.
As I stated in the discussion item, I would like to be able to use PMTiles instead of OGC web services, provided that all "flavours" of PMTiles (MVT, raster, elevation) cover the requirements for iTowns to work. If so, it is my opinion that functional requirements for iTowns could be dramatically relaxed : no web server needed, just simple http access to files. Simplicity in using different basemaps and other map artifacts than what is currently provided would make iTowns easier to personnalize for other organizations, especially those that do not have the breadth of OGC web services currently needed to accommodate iTowns.
I would like this PR to serve as a starting point for discussing the integration of "cloud-native" file formats in iTowns. The example provided is just to show PMTiles of MVT type can be overlaid in iTowns. My hope is that a well prepared PMTiles could provide the same output than OGC services and therefore could be a substitue rather than mererly an overlay.
