[mkgmap-dev] documentation improvement

From Gerd Petermann gpetermann_muenchen at hotmail.com on Wed Apr 8 06:34:29 BST 2020

Hi Mike,

I've attached the template.args generated for this command:
java -jar d:\splitter\dist\splitter.jar --description=test --max-nodes=100000 --geonames-file=f:\osm\cities15000.zip  f:\osm\bremen-latest.osm.pbf
java -jar d:\splitter\dist\splitter.jar --description=test --geonames-file=f:\osm\cities15000.zip  f:\osm\niedersachsen-latest.osm.pbf

Note that the one for Bremen is special because some tiles get the default description given with the --description option.

Hi Gerd & Ticker,

Please find an updated patch that includes the essence of your comments on the --description option (I hope). Please let me know if you think further tweaks are needed.

Note, I'm not clear on the effect the splitter --geonames-file option has on the description. The splitter documentation only indicates it affects the file names of tiles. Does the splitter documentation need something adding?

There is still the question of whether the quote symbols need to be replaced with 'arc seconds' or whether the HTML creation process should be amended.

Also, clarification on the 3314/3312 values in --dem-dists.

Hi Gerd & Mike

@gerd - as you say, it is better to just improve the documentation of
what is there. As far as I could see it was only the tiles and gmapsupp
that took the --description.

I'd suggest changing from:

:       Set the descriptive text for the map. This may be displayed in
QLandkarte, MapSource or on a GPS, where it is normally shown
below the family name. Example: --description="Germany, Denmark"
Please note: if you use splitter to build a template.args file
and pass it to mkgmap, then that file may contain a "description"
that will override this option. To prevent splitter from overriding
your description, place the --description option
after "-c template.args".


:       Set the descriptive text of map components.
Map tiles take the most recent --description before the --input-file
that defines the tile.
gmapsupp.img takes the last --description.
Note that the splitter generated template.args includes
relevant --description values (see splitter --geonames-file).
The usage of the component descriptions is not consistent between
GPS devices, MapSource, Basecamp and QLandkarte.
Some use the --family-name to enable the complete map, others use the
gmapsupp.img description.
Some devices can enable individual tiles using the tile description.
Suggested usage:
  ... -c options.cfg -c template.args --family-name=Scandinavia
  --description=Scandinavia --gmapsupp typFile.txt

@mike - if you & Gerd are happy with something like this, do you want
to put it into your patch, otherwise I'll do it once your option
changes are out of the way.
