Sorry to bother you again about this topic,
I played a little bit with +lat_ts but I did not find any simple
explanation about it.
From what I experienced with QMS :
With +lat_ts = 89 highest detail level is available even when zooming
out quite far but zooming in is quite limited
With +lat_ts = 60 I am happy
but I am happy and ignorant (I know that knowledge does not always mean
happiness, but I would accept a little more knowledge taking the risk to
be a little less happy :)
Can you explain a little bit ?
Thanks a lot

Thanks Oliver!
By adding +lat_ts=xx.x to the projection string (where xx.x is the
current latitude of the displayed place) + by choosing "square"
(optimized for TMS and WTMS tiles) I get even more space than with QLGT.
The only (minor) drawback is that a grid is visible on hillshading but
this is not a big deal.
Bye!

QLGT used latitude of true scale (+lat_ts=) in the projection string.
That's
why scaling will not match 100%. You can add the lat_ts parameter to
your
projection string if you really want to a have a more or less 100%
match.
However QLGT does this dynamically for the center point of the loaded
map. So
it's a bit of a running target.
But else the scale to bit relation is the same. You can cross check it
yourself. In QLGT
CMapTDB::scale_t CMapTDB::scales[] =
and in QMS
quint8 CMapIMG::scale2bits(const QPointF& scale)
I checked the levels up to 20 bit. They match.

in the previous email setting is "log".
In this attached screenshot it is "square" : it is larger but still not
as large as QLGT.
Thanks !

Same test with QLGT (see attached screenshot) gives the same result :
it looks like QMS detail level is set one step below QLGT.
My main concern is that with QMS displayed area is smaller.
(other possibilites are to buy a bigger screen or to print my maps :
that is a big advantage of paper maps : highest detail level is
available at every zoom level :) )
Bye
