Tricks & Tips : multiple tags

Problems with multiple tags:boundaries

More Tricks

Today, many rivers,highways have an added 'boundary' tag. This saves space but can also lead to unexpected results.

boundary no river boundary & river
boundary no river boundary & river

As I had all my boundary tags at the beginning of my lines file, I forgot to add 'continue'

boundary=administrative [0x1c resolution 24 continue]

Problems with multiple polygon tags:tourism

Again , be prepared for unexpected tagging. Loch Ness is tagged as natural=water AND tourism=attraction

I had both tags as solid polygons and tourism had a higher draworder in my TYP file.

In my case, I'm not too bothered about showing tourism polygons so added:

natural=water & tourism=attraction {delete tourism}
