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

Tue Oct 6 08:19:40 BST 2020

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
