[mkgmap-dev] mkgmap:area2poi placement

Wed Apr 6 14:02:24 BST 2022

Ok,
I've now managed to delete the poi with this line:
boundary=national park & mkgmap:area2poi=true & is_in(boundary,national_park,in_or_on)=false {delete boundary}

I also want to use it for all boundaries but this line is not working:
boundary=* & mkgmap:area2poi=true & is_in(boundary,*,in_or_on)=false {delete boundary}

How can I use the wildcard? According to the style manual this should be possible:

is_in(tag,value,method)
true if the element is in polygon(s) having the specified
tag=value according to the method, false otherwise.
value can be '*' which matches any polgon having tag. The
methods available depend on the Style section

________________________________

I don't see a way to control the placement of the POI for a
multipolygon; it sets it to the centre point of the biggest area.

You could suppress the POI if it isn't within the area by using the
is_in() function, something like:

tag=value & mkgmap:area2poi=true & is_in(tag, value, in_or_on)=true
