Masking the sea using the gradient #8

Hi, thanks a lot for this awesome tutorial.

Regarding the last section, extra mask for aoi.

I found that a cheap way to put appart the sea from the land is to add a left color to the gradient, very low, 0.011 in my case.

Looks fine :)

Also, I found this site really cool to get the boundary shape : http://polygons.openstreetmap.fr/index.py

Hi! Yes, but be careful as you will often flood coastal areas by doing this. I have often found that not even 0.00000001 is capable of differentiating between land and sea, which is why I recommend using a mask.
