Hi Felix,
I just wondered, is mkgmap now producing fully working maps if the highest resolution is 23 instead of 24? (meaning no problems with autorouting, no problems with simplyfing filters, address search and so on?).
no, it is not :-( It turned out that there are special cases , see also http://gis.19327.n5.nabble.com/Mapsource-crashes-while-calculating-a-route-t... I still see this on the todo list, but if nobody else tries to solve it, you'll have to wait a bit, as I prefer to go biking in the summer ;-) okay - enjoy the sun.... - I'm sure you deserve it!
BTW - if it is - it would be cool if one could specify "0x1c resolution highest" or "0x1c resolution X" instead of 24 or 23 to quickly change between producing a map with resolution 24 and 23 for testing... (I
know
this could be done with using level instead - but for me using resolution is easier because when editing a style-file I can assess the outcome much easier than needing to remember with level is which resolution. Also it's easier to play around with levels that way - the only problem is that each time I would need to run a script to change resolution 24 to 23 as I don't want to do this in the style-file I use for editing itself as it's a way of no return if you want to have 23 and 24 in the map again).. Or is it possible to replace just "resolution 24" in the style-file with "level 0" while keeping all other at resolution ?? and still using the options file to get the other resolution ?? assigned to their proper level?
that's what I did to create a routable map at res 23: http://gis.19327.n5.nabble.com/Mapsource-crashes-while-calculating-a-route-t... okay perfect. That makes it easy. I doubt anyone would want to create a routable map at resolution=22 or lower.
IMHO for a scrict car map like "City Navigator" resolution 23 is plenty... Actually for an intermediary step if it's easier. Would it be possible to have a map with level 1= 22, level = 23 for polygons and POI and 24 for lines? It seemed to me that garmin fiddled around in some maps in this way to save space. However to create a map for all of Europe <4GB I would still say we need to get resolution=23 as level 0 fully working (the rest of the work is to slim down the style-file properly - but only cutting down the style-file would be a too big compromise). Well - maybe good work for next winter...
