== Description ==

The mappaint style "Incline" displays up/down arrows at the first and last node of ways with [osmwiki:Key:incline incline=*].

You can adjust the colours of the arrows in the preference window of JOSM.

You can use the Incline mappaint style together with the default JOSM internal mappaint style. You can display the arrows one zoom step earlier by changing the [wikitr:/Help/Dialog/MapPaint/StyleSettings style setting] of this style.

For ideas/questions/bugs/suggestions or similar please write a message to [osmwww:user/Klumbumbus Klumbumbus].

Feel free to translate this wiki page into more languages. Already translated languages see top right.

Note that the up arrow is always above the node and the down arrow always below the node, independent from the cardinal direction of the way. So don't be confused (see first and fourth example from the left in the image below).
