<br>
yes, I think that message makes no sense in this situation. I am not sure why I decided to log this as an error.<br>
See <a href="https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3679" rel="noreferrer" target="_blank">https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3679</a><br>
<br>
I've attached a patch to suppress the message if the input file is a ovm_*.img.<br>
I could also simply reduce severity to warning or remove it for good.<br>

Betreff: [mkgmap-dev] How to create an empty overview map (for transparent maps)<br>
<br>
If you create a separate map for buildings or contourlines only - usually there is no need for an overview map - or better no need for any content in the overview map - or am I missing something?<br>
<br>
Because those maps sometimes may have very large tiles, but very few levels (maybe only 24) - mkgmap creates an overview map at the next resolution - and will then often throw warnings such as:<br>
<br>
SEVERE (OverviewBuilder): Tile selection (0x4a) polygon for tile 84900000 cannot be written in level 0 resolution 21, using 20 instead<br>
<br>
<br>
There is still a need for an empty overview map - as without it you cannot show the map in Basecamp/Mapsource - or transfer it with MapInstall.<br>
I know the overview map is only empty 0x4a polygons - just wondered if there is a better solution...<br>
<br>
--overview-levels=<br>
is not given.<br>
