[mkgmap-dev] POI barrier/access restriction

Tue Apr 14 14:07:39 BST 2020

Hi Ticker,

it is difficult to find good rules for barriers Many people don't map the access rights and thus it is hard to say what defaults should be used.
At least that was the case when I changed the rules in 2013 ;)

In what situations do you see improvements with your patch?

Gerd

Hi Gerd

The only common bit is filling in the mode hierarchy. It could be moved
into an include and shared, but it is only 15 lines.
