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.

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 Ticker _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
