Hello everyone,
In trying to render contours divisible by 50m in different width to other
contours, I've tried adding the modulo operator to the mapnik xml file. I've
tried both
[height] % 50 = 0
and
[height] mod 50 = 0
However neither of these are recognised... can it be done?
This is for a revised rendering approach for my countryside OSM maps:
previously I used my own srtm to shapefile code, and just added an extra
shapefile key for heights divisible by 50, but now I am using the geotiff
approach used in the cycle map. The cycle map rendering notes suggest you use
multiple layers, one for 10m and one for 50m, but would prefer to avoid that if
possible.
Thanks,
Nick
