Hello,

i make my own maps with mkgmap and use them on a Dakota 20, Oruxmaps 7.02 and Oruxmaps GP. While everthing is ok in Basecamp and on the Garmin Dakota 20 i have problems with Oruxmaps.

Garmin knows 24 resolutions. Here are the commonly used ones form
https://www.mkgmap.org.uk/doc/pdf/style-manual.pdf

 16  30km-12km
 18  8km-3km
 20  2km-800m
 22  500m-200m
 23  300m-80m
 24  120m-50m

The appearance of map items is also based on those resolutions.
For example a supermarket: 

amenity=supermarket [0x2e02 resolution 24]

That means a supermarket (and its symbol) is only at max zoom 24 visible.

Oruxmaps only knows 21 resolutions. The zoom is very different. Wich wasnt a problem if the amenities wouldnt appear on Oruxmap level 15 and completely clutter the screen.

Here screenshots. They show the resolution when the amenities first appear.
basec.png is from Basecamp, dacota from teh Garmin Dakota and the two screenshots from Oruxmaps 7 and GP.

Oh, and by the way. Why does oruxmaps not have a pin like the Dakota ?
