<p>Hi Thomas,</p>
<p><br>
</p>
<p>okay, I'll dig into this during the next days. My understanding so far</p>
<p>is that the ovm_*.img tiles do not contain 0x4a polygons and that the <br>
</p>
<p>code adds just one 0x4a polygon for the overview map. Maybe this is split</p>
<p>into pieces because some size limits are reached...</p>

<div class="PlainText">Hi Gerd,<br>
<br>
please make a really solution of the error or untouch the code. No error <br>
mesasage ! Maybee a error message prevent mkgmap to create the _mdr.ing. <br>
I use a workaround with cgpsmapper to create the preview.img. I am <br>
angry, that my workaround wil lnot longer work, if mkgamp gives me error <br>
message.thank you.<br>
thomas<br>
<br>
by the way... : the problem is: mkgmap creates many 0x4a for one <br>
maptile. it should creates only one 0x4a with the tile-boundaries, like <br>
in the corrresponding tdb. Maybee is the solution, to use the same <br>
algorythmus for writing 0x4a in preview like in tdb ?<br>
