Point styling
-------------
To provide a consistent density gradient as you zoom, the Mapbox Studio style needs to be
coordinated with the base zoom level and dot-dropping rate. You can use this shell script to
calculate the appropriate marker-width at high zoom levels to match the fraction of dots
that were dropped at low zoom levels.
If you used `-B` or `-z` to change the base zoom level or `-r` to change the
dot-dropping rate, replace them in the `basezoom` and `rate` below.
awk 'BEGIN {
dotsize = 2; # up to you to decide
basezoom = 14; # tippecanoe -z 14
rate = 2.5; # tippecanoe -r 2.5
print " marker-line-width: 0;";
print " marker-ignore-placement: true;";
print " marker-allow-overlap: true;";
print " marker-width: " dotsize ";";
for (i = basezoom + 1; i <= 22; i++) {
print " [zoom >= " i "] { marker-width: " (dotsize * exp(log(sqrt(rate)) * (i - basezoom))) "; }";
}
exit(0);
}'
