Reads spatial data stored in Geography Markup Language (GML) format and decodes the geometries into WKT (Well-known Text Representation). Decodes every attribute of the spatial features as a column of a corresponding KNIME type.
Note that KML data is always assumed to be encoded in the Coordinate Reference System EPSG:4326. If you have problems with further processing of spatial data, you might try to reproject to another CRS using the "Reproject WKT geometries" node.
GML is a complex format; it is not a totally defined format, but more a family of formats which can be tuned by schemas. There is no reference validation tool for developers to ensure their code writes or reads these formats properly. As a consequence, writing and reading GML features remain an uncertain experience.
The actual decoding of the GML format is done by the geotools library.
