Hi Daniel,
I don't know for sure but I think you may have to set option --levels or
--overview-levels to the values that you want.
There is a hard-coded default for --levels in mkgmap:
public static final String DEFAULT_LEVELS = "0:24, 1:22, 2:20, 3:18, 4:16";
and the options file in the default style overwrites this:
levels = 0:24, 1:22, 2:20, 3:18
overview-levels = 4:17, 5:16, 6:15, 7:14, 8:13
So, you have different places to check.
I've found the levels line in the *.cfg file I use.
After adjustment, it works now, thanks!

resolutions
Hi all,
I want to generate an overlay map with contour lines. The following
style works as expected:
contour=elevation & contour_ext=elevation_minor & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x20 resolution 24]
contour=elevation & contour_ext=elevation_medium & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x21 resolution 20]
contour=elevation & contour_ext=elevation_major & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x22 resolution 17]
Major lines are visible up from resolution 17, medium from resolution 20
and minor on highest resolution (24).
If I change the style to:
contour=elevation & contour_ext=elevation_minor & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x20 resolution 24]
contour=elevation & contour_ext=elevation_medium & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x21 resolution 21]
contour=elevation & contour_ext=elevation_major & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x22 resolution 17]
Major lines are visible up from resolution 17, but together with medium
lines, minor lines are visible starting from resolution 21, too.
Same effect for choosing resolution 22 or 23 for medium lines. Medium
and minor lines are visible always together for medium-resolutions >= 21.
As the effect is the same on QMapShack and GPSMap 66s, I assume the
problem is in the map.
Any ideas what can cause the problem? What I finally want to build is:
contour=elevation & contour_ext=elevation_major & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x20 resolution 18-21 continue]
contour=elevation & contour_ext=elevation_minor & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x20 resolution 24]
contour=elevation & contour_ext=elevation_medium & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x21 resolution 23]
contour=elevation & contour_ext=elevation_major & (ele > 0 | ele < 0) {
name '${ele|conv:m=>ft}'; } [0x22 resolution 22]
I've reduced this to the styles above to isolate the problem.
