Possible CartoCSS advances for more dynamic styling with zoom

Zoom as a dynamic token in selectors

Common usage of the special zoom filter keyword looks like:

#roads[zoom=10] {
   line-width:2;
}

MapBox Cloudless Atlas Tour

Speakers notes

Part of a presenation given at NACIS 2013: https://github.com/springmeyer/cloudless-nacis2013

  • Bahamas - land really pops due to blurred shallow nearshore
  • Australia - rich hues
  • Great Barrier Reef - Extremely subtle textures visible + water mask helps show smallest reefs
  • Amur River - effectively shows many combined flood events / murky water in delta
  • Taiwan - deforestation clearly visible
  • Tibet - Jewel lakes
