Nice work! I'm guessing you're using the Mapzen tiles via AWS? Any idea if it's possible to indicate the grid resolution for the extract area? Eg, I extracted 1m contours for an area, but the grid resolution appears to be about 10m or so, meaning the 1m is overkill

Yes, this is useing RGB terrain tiles hosted on AWS. Good point! I will look into that. Maybe I should just set the minimum contour interval to minimum tile grid. Thanks for the feedback!
