The overview map is only for Basecamp/Mapsource/Qlandkarte GT - so on
desktop. On device it get's faster - because the normal map doesn't need
to go down to zoomlevel 16 or 14 anymore - and the device BASEMAP can
get in earlier (and the Basemap is much faster than rendering several
tiles at once).
The missing link is now much more that we could create a simple Basemap
that is non routable - to replace routable basemaps on newer garmins
that interfere with routable mkgmap maps - (because many people now opt
to simply drop the garmin basemap because of this)...
(that basemap if done well, shouldn't need to be updated more often than
every 5 years or so - only basic information needed).

I'd also like to thank everyone involved in implementing this feature.
I have not yet tried the new overview map on a device, but I can
confirm that map display is considerably faster in Basecamp on Mac OS
X. In addition, the overview map makes the selection of map tiles in
MapInstall far far easier (used to transfer the selected map tiles to
a GPS device).
Excellent work.
Cheers.

This is great news. The overview map was one of the biggest
deficiencies in mkgmap until now.
So thanks to Gerd and well done.
Also a lot of bugs have been fixed along the way, so I would like to
acknowledge that too.
I will put up a news item on the website this evening and push out
notices to freecode.

Hi all,
finally I've merged r2629 into trunk.
A brief description of the changes:
1) new or changed options
--overview-levels
like levels, specifies additional levels that are to be written to the
overview map. Counting of the levels should continue. Up to 8 additional
levels may be specified, but the lowest usable resolution with MapSource
seems to be 11.
--remove-ovm-work-files
If overview-levels is used, mkgmap creates one additional file
with the prefix ovm_ for each map (*.img) file.
These files are used to create the overview map.
With option --remove-ovm-work-files=true the files are removed
after the overview map was created. The default is to keep the files.
--polygon-size-limits=limits code
Allows to specify different min-size-polygon values for each resolution.
Sample:
--polygon-size-limits="24:12, 18:10, 16:8, 14:4, 12
:2,
11:0"
If a resolution is not given, mkgmap uses the value for the next higher
one. For the given sample, resolutions 19 to 24 will use value 12,
resolution 17 and 18 will use 10, and so on.
Value 0 means to skip the size filter.
Note that in resolution 24 the filter is not used.
2) Optimizations:
- The polygon filter allows larger polygons.
- SeaGenerator generates fewer "sea-only" and "land-only" polygons when
precomp-sea is used.
Both reduce the img size, esp. for maps containing large "sea only" areas.
3) Changes regarding styles:
- The support for the out-aged map-features.csv file was removed
- Level ranges can now use min-max or max-min
- Usage of polygon type 0x4a will be flagged with --check-styles
4) Other changes
- A few checks are performed regarding the plausibility of the given options
and input files
to help beginners.
