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
