[iTowns-user] How can I pull initial zoom level imagery from local files?

[Terek Campbell]

Hello,

I'd like to store the initial camera's zoom level's images (25 million
meters) as local files so that if a connection to our GeoServer is
unavailable, there will still be a low resolution view of the globe
available.

My thought was to use an iTowns.FileSource combined with a config similar
to iTown's Ortho.json but with all but the first couple tileMatrixSetLimits
removed. Then having my second imagery layer providing all zoom levels
after 3 by the typical means.

I'm not sure how to use a FileSource to pull imagery data locally. Can
anyone shed some insight?
