Hi all, we came accross this in this discussion : http://gis.19327.n5.nabble.com/Option-to-output-polygons-in-size-order-tp587... The polygons file contains these two rules: place=island & name=* [0x53 resolution 19] place=islet & name=* [0x53 resolution 20] I assume they were added to "catch" small islands within lakes, but they are producing really large and complex polygons for islands like the monster mp-relation 6038068<https://www.openstreetmap.org/relation/> which covers the mainland of the UK. According to GPS MapEdit the polygon type 0x53 seems to stand for "Sandbank, tidal/mud flat", which might be good for very small islands/islets, but makes no sense for really large islands. What would be missing without the 1st rule, esp. when precompied sea data is also used? I can think of adding more clauses, e.g. place=island & name=* & natural!=coastline ... place=island & name=* & area_size() <= 100000 ... Any thoughts? Gerd
