Jose, the GeoTools bindings for Polygon assume that gml:exterior is a gml:LinearString: https://github.com/geotools/geotools/blob/master/modules/extension/xsd/xsd-gml3/src/main/java/org/geotools/gml3/bindings/PolygonTypeBinding.java#L101
I do not know why the geometry is a String at that point. I suspect that this encoding pattern is unsupported. I can confirm that, if I modify your original XML to use gml:LinearRing / gml:posList, it parses cleanly, as your reported: <gml:Polygon xmlns:gml="http://www.opengis.net/gml/3.2"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/gml.xsd"; gml:id="GSE001"> <gml:exterior> <gml:LinearRing> <gml:posList srsDimension="2">[...] Kind regards, Ben.
