Now it's possible to put the Geometrytype which + is required to generate the Layer and not use the Geometrytype of the + first Geometry of the Resultvalues. + This was nessessary because we can have several kinds of geometrytypes + (e.g. MultiPolygons and Polygons) in one Layer. In that case we have to + use the Multi* (e.g. MultiPolygon) as Geometrytype. + * doc/conf/queries.properties: + Added Query for determining the geometryType of a Layer. + 2010-04-06 Sascha L. Teichmann <sascha.teichmann@intevation.de> * src/main/java/de/intevation/gnv/**/*.java: Fixed vim modeline.
