Get other resolution tiles at the same time

[jidanni]

Maybe have a quick setting, that enables us to get higher / lower magnification tiles at the same time we're sweeping along getting tiles.
Yes I know we can download an area, I'm talking about sweeping along vacuuming up tiles for later use offline.

For instance, we are sleeping along the valley, and at the same time getting the nearby hills too.

So perhaps allow a width, and a magnification range, of additional tiles, to get at the same time we get the usual tiles.

Hi,
Storing higher zoom levels would be difficult as it would quickly require to store huge amount of data (without any information on the storing progress), however for previous zoom level that may be possible.
Let's add it in the wanted features list.

Yes, storing those lower resolutions, makes perfectsense, and would require exponentially less space than the one we are getting now, so yes, allow it!

You should put it as a checkbox in this dialog.

Just today I had to run it once for magnification 19, run it again for magnification 18,.. big hassle.

You can even have a choice of how many zoom levels to also get: one less than current, two less than current, three less than current, etc

By the way, you notice I have the force update checkbox checked.

Well I discovered that even doing that, wasn't as good as doing Control-F5 in a browser!

So you are just getting tiles from upstream, you're not asking upstream to refresh caches, as good as a browser could!

So maybe also have another checkbox, to even force refreshes through http tags.

Map servers refresh their data and cache based on their own policy, not based on (millions) of users will... And I don't even think there is a way to ask this to a map server...

Maybe when there are various Clloudflare, etc. along the way

headers might still help.

This is for the HTTP protocol.
Map servers mainly use WMTS: https://www.ogc.org/standard/wmts/
