[mkgmap-dev] Line direction flag, merging etc

From Gerd Petermann gpetermann_muenchen at hotmail.com on Mon May 17 12:13:15 BST 2021

Hi Ticker,

I do see a need for the --allow-reverse-merge option, at least for those styles which rely on the old behaviour that lines are not reversed unless oneway=-1 is found.

Gerd

Betreff: Re: [mkgmap-dev] Line direction flag, merging etc

Considering the question of hasDirection and resolution.

If the same lineType looks identical, regardless of hasDirection, then
there is no point in setting hasDirection=true as the only effect will
be to inhibit merging.

To get the look of direction at high-res and no-direction when zoomed
out, different lineTypes have to be used, with the style controlling
this with [resolution-range] and [continue]

If the lineType representation can be changed with hasDirection, again
elements for the different levels should be produced, but can have
 {set mkgmap:has-direction=yes} for the high-res and =no for the low
-res
