[mkgmap-dev] Styling for the power user: filtering contour lines

To Christian Gawron Thank you for your tip. I will try to use it for the next release of my map. David

Hi Daniel,

you can use regular expressions to filter contour lines by elevation - here is what I do in my style file:

# Contours take their name from the elevation setting. # multiples of 200m contour=elevation & ele ~ '\d*[02468]00' { name '${ele|conv:m=>ft}'; } [0x22 resolution 18] # multiples of 50m contour=elevation & ele ~ '\d+[05]0' { name '${ele|conv:m=>ft}'; } [0x21 resolution 21] contour=elevation { name '${ele|conv:m=>ft}'; } [0x20 resolution 23]

You could use '\d+[27]5' for your purpose.

Best wishes Christian
