title: Plant health tile layer
body: <p>Hi i've displayed my dronedeploy map with leaflet.js.</p>
  
  <p>Is it possible to add dronedeploy's Plant Health (NDVI) layer to that map?</p>
  
  <p>Also i was able to add ndvi layer using  <a href="https://tiles_2_prod.dronedeploy.com/unsafe/smart/filters:vegetation_index(NDVI,0.2,0.5,NGB):cmap(RdYlGn)/" rel="nofollow noreferrer">https://tiles_2_prod.dronedeploy.com/unsafe/smart/filters:vegetation_index(NDVI,0.2,0.5,NGB):cmap(RdYlGn)/</a> 
  as a prefix. </p>
  
  <p>Problem is i've hardcoded 0.2 and 0.5 as thresholds and i would like to use dronedeploy's calculations. </p>
