<div dir="ltr"><div dir="ltr">at 300m there is no difference at all. Actually the patch will help you to set lower DP level for 300m (that is resolution 23 in Basecamp) while giving higher DP values for higher resolution. That came because for contourlines it needs very low DP value for resolution 23, while if you keep that low DP value for higher resolution, it makes the map unusable on device and even slow in Basecamp.<div>resolution 22=700m</div><div>resolution 21=1.5km</div><div>resolution 20=3km</div><div>resolution 19=7km</div><div>resolution 18=15km (if you use high DP filter - this is the first resolution where the simplification will mean the route is visually quite different from the underlying road, but still very easy to know which road it belongs to(</div><div>resolution 17=20km</div><div>resolution 16=50km</div><div>.....</div><div><br></div><div><br></div><div>with default style:</div><div><br></div><div><div>levels = 0:24, 1:22, 2:20, 3:18</div><div>overview-levels = 4:17, 5:16, 6:15, 7:14, 8:12 <br></div><div><br></div><div><br></div><div>So 17 will never actually be shown on your device.

<div>Hi Karl,</div>
But even then you will never use the overview map.
<div><br>
</div>
<div>What resolution are you actually using on your device if
routing on a highway? I guess 19 or 20... </div>
<div>The thing is simply with high DP filter value that you can
see the highway pretty straight, but as the route itself is not
simplifed that much in Basecamp. The route will not be 1:1
visually of the map. But still very easy to see the the
underlying highway. if you plan a route from Berlin to Mardrid,
then zoom out and see the whole route - then it's not so
beautiful anymore. But can any mkgmap created map actually route
from Berlin to Madrid without via points? It's a long time that
I looked at mgkmap created maps for car routing and some years
ago this was not possible.[/qoute]</div>
