In the natural earth file ne_50m_geography_marine_polys I'm selectively
displaying the label of a feature based on zoom level and the relative size
of the feature. There's a field called "scalerank"  that's an integer in
the 0-6 range that indicates the relative scale of the feature - e.g. the
Atlantic Ocean is a 0, the Mediterranean is a 1, and the Chesapeake Bay is
a 4. I'm using this number to determine the maximum zoom level
(label_level) for displaying the label for that map feature.

Oceans were no problem as the data type is an integer.  After some
frustration I figured out that the same field name in a different file (
ne_50m_lakes ) is a float. Once I figured that out I found a RE to match it.

Thank for confirming what I had guessed.
