I'm sorry for not giving feedback. I'll try to test updated mkgmap in
the following days and report any issue. I suppose best way to detect
overview map size problems is processing a big map, such as Europe or Asia.

Hi Ticker,
my concern was not about the number of additional bytes on the disk, but the
size limits in IMG format. Anyway, since nobody else commented we probably only
find out when someone hits that limit, so I've committed the patch (first v5,
than changes from v6, sorry for that) with r4599.

Betreff: Re: [mkgmap-dev] Tiles pruned in DEM map
Hi Gerd
Given that the overview map is for use on computers with 100s of G of
disk space and the main map will be a G or so, can an extra few 10K or
so in the overview map really be a problem for anyone?
Building British-and-ireland, with default style and just --gmapsupp
(ie no index or routing) gmapsupp.img is 542M and osmmap.img is 220k.
With --order-by-decreasing-area they increase to 603M (11.3%) and 228k
(3.6%).
With routing, indexing, code page 1252 and other typical options,
gmapsupp.imp might be double the size and so the percentage increase
would be a lot less but not significantly different for osmmap.img.

Hi Ticker,
outch, sorry! It seems I created my patch without any testing :(
I'm still not happy with the handling of the --order-by-decreasing
-area option. I wonder why nobody else comments on this. Either
nobody cares about the size of the overview map or nobody else tried
any of the patches. Since this is a major change I hoped for more
feedback.
