[MapProxy] How to understand field_filter

[Lars Lingner]

Hello,

how should I understand the field_filter in the mapping file?

Looking at [1] I'm missing a comparison value, but then I probably don't
understand it. The docs [2] are sounding promising, as I want to
include/exclude objects with a certain value.

So in this case I would like to have only objects with a area value
greater 50. I don't need the area values in the database.

Thanks for any help.


Lars
