title: CartoCSS: style a layer based on proximity to another layer
body: <p>I am trying to replicate a google maps style in CartoCSS with Map box studio classic. A default google map has a light brown shading for the industrial area surrounding an airport (as in the screenshot)</p>
  
  <p>Google Maps San Francisco Airport - the target style</p>
  
  <p><a href="https://i.stack.imgur.com/jNaWI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jNaWI.png" alt="Google maps - San Francisco airport"></a></p>
  
  <p>Mapbox San Francisco Airport - the current style</p>
  
  <p><a href="https://i.stack.imgur.com/BTHyu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BTHyu.png" alt="Mapbox San Francisco Airport"></a></p>
  
  <p>The area "underneath" the airport is classed as #Landuse['industrial']. I'm looking for a method to give this area the light brown shading but leaving all other industrial areas unaffected. </p>
  
  <p>I'm thinking down the lines of applying a style to any #Landuse['industrial'] which is in proximity to any #aeroway layer. So the question is: Is this possible and/or is there a better/easier way to achieve the desired style.</p>
