Hi Gerd Thanks for your reply Yes, I noticed that level 2-4 is allowed as well. Just going back to an earlier problem, using the default levels levels = 0:24, 1:22, 2:20, 3:18 overview-levels = 4:17, 5:16, 6:15, 7:14, 8:12 a) I'm still a bit unclear about what happens if a resolution a) slots in between two levels , ie resolution 19 will between levels 2 and 3 Will if always get rounded down or does it depend on the nearest level ie levels = 0:24, 1:22, 2:20, 3:15 resolution 17 will be plotted as level 3 ? resolution 19 will be plotted as level 2 ? B) the default style's lowest resolution is 10 in Polygons and yet its is lower than level 8 in which case its rounded up to level 8 or does it automatically get assgined a new undeclared level 9? Just realised 4b must get hard coded to the lowest level (0 ?) Regards Nick On 13/03/2020 13:43, Gerd Petermann wrote:
Hi Nick, a) natural=wood [0x50 level 2-4 ] is allowed. b) a level larger than specified in levels gives an error message. For your example I'd expect Error in style: Error: Level number too large, max=5 Not sure if that makes sense. For your example I would have expected that area_city=* [0x03 level 6 continue] is treated like area_city=* [0x03 level 0-5 continue]

Hi Gerd
Thanks that's clear.
I'm just experimenting with the default style rather than my own which is entirely geared towards hiking.
I can see there is some advantage using levels:
a) you get a clearer picture of which elements get plotted at which zoom level
b) you only have to change the resolutions in the options file to test the zooming effects.
btw
a) Can you use the '--' in levels?
ie
natural=wood [0x50 level 2-4 ]
b) I have seen an options file which contains levels 0 --> 5
However in the style itself there is mention of a level 6 eventhough it's not defined in tghe options file
ie
area_city=* [0x03 level 6 continue]
Is that 'allowed' ?
Regards
Nick

Hi Nick,
The behaviour changed in the past, but I think if the style produces an object for a max resolution X and no level covers exactly this resolution the max resolution is decremented to the next lower value covered by a level. If there is no such level the object is not added to the map.
natural=coastline [0x15 resolution 12] is equal to natural=coastline [0x15 resolution 12-24]
Not sure what you mean with "I remember in the past it was said the levels are better than resolutions" Do you suggest to change the default style to use level instead of resolution?

Hi Gerd
Just to be a nuisance:
If there is no level beyond level 3 in the default style, ie 4,12
then all resolutions <18 contained in the default style (and there are quite a few!) only get plotted at level 3?
ie the lowest lines are a boundary and a coastline , both at res 12
Do they only get plotted at level 3 , ie resolution 3
I remember in the past it was said the levels are better than resolutions

Hi Nick,
the meaning of these statements depends on the levels option. With the options in default style levels = 0:24, 1:22, 2:20, 3:18 the resolution 23 and 22 are at level 1, so resolution 23 is actually rounded down to 22.

Hi
Can anyone tell me what exactly the '-' in after resolutions means.
I plotted a church resolution 21-23 only to find it does not include resolution 23.
Somewhere I read that only the resolutions between the numbers are plotted.
If that is the case what does 23-24 mean ? What resolution is there between 23 and 24
What happens with resolution 23-23 ?
Does 23-24 mean only level 23 Is 24-23 different from 23-24?
The manual does not seem to tackle this issue.
btw
Have noticed that Basecamp/Mapsource only plots 0x2c poi range at level 24
So the following might never occur in some GPS devices is except at resolution 24
0x2c02 [resolution 21 ]
This seems to affect :
viewpoints,churches,castles, schools,amusement parks etc
Regards
Nick
