[mkgmap-dev] Test if POI is part of a line

Hi (another) Felix,

yes, you can omit the clause mkgmap:line2poi=true.
I've only added this check to make clearer that the rule only works with the --add-pois-to-lines option.

I'm new here (Hello!), so please be patient if I'm missing points ;-)

But couldn't you check whether the line the point is attached to later on would become a routable line? Basically, because the points inherit all tags from the lines when using --add-poi-to-lines, by running through the same decision tree that (later on) is used in the lines file already in the points file? Optimally from some clever include file to avoid redundancy?

@ Gerd

Why is "mkgmap:line2poi=true" required? Shouldn't only acting on mkgmap:from-node:barrier=gate in conjunction with the lines tag suffice here?
