legend for displayed raster - API

[mkoo]

For @bkg in API add grayscale (0-255) ramp which is required for color ramp customizations on the raster tool

[bkg]

@syntagmatic, turns out that a grayscale style is available by passing the style param, e.g. https://ecoengine.berkeley.edu/api/tiles/tasmin_yr_ens-avg_amon_rcp85-2099-01-01/4/3/6/?style=Greys. Let me know if this will suffice for the client side color ramps.

Excellent, thanks @bkg!

Black corresponds to the max value and white to min, or vice versa?

[bkg]

That's right, but you can flip the ramp using style=Greys_r if you like.

Thanks! I repaired this example: http://stamen.github.io/ecoengine/prototypes/tiles/colorscale.html

Legend coming soon
