[mkgmap-dev] question about output-dir and indexing

Tue Oct 6 08:32:21 BST 2020

Hi Karl,

better combine (merge) the input files first and feed the combination to splitter.
Use e.g. osmconvert [1] to merge  the files, e.g.
osmconvert denmark-latest.osm.pbf finland--latest.osm.pbf norway-latest.osm.pbf -o=scandinavia.o5m
java -jar splitter.jar ... scandinavia.o5m

Make sure that you download all the merged files at the same day to avoid version conflicts.

reg. deletealltags: If you don't want parkings in your map you should better remove/comment the rules which would create those objects.
This allows mkgmap to ignore the unwanted objects much earlier.

Hi Gerd and Carlos.
Both your commends made a difference in moving forward!

Two more questions before i dig deeper on my own.
I will be trying to make a map of the scandinavian countries, denmark, norway,
sweden.
It safe to generate each country first by using country data from geofabrik,
compile tiles for each country and then combine the three to one gmapsupp or
will that make border areas inaccessible because maps tiles overlay each
other?
If this is not a good way, what is a good way?

If i want to make a minimalistic map, and remove a lot of things.
Say all parkings. is it correct to use the deletealltags for the types of data
i want to remove?

Regards
Karl
