Reduce number of "small" fields?

[m-mohr]

Some parts of the world (e.g. spain) create a lot of little fields, making the results very large and hard to process by the browser. Should we include smaller fields by default or only show a subset or ...?

I think there may be an option in the vectorization code to just filter out smaller results. I think we could add it as a control in the 'expert mode', and put the default a bit higher than it is.
