Hi,
i'm currently trying to export some Files in GML. The export works fine so
far and i can import the .gml-files in QGIS, but other tools fail because of
the validation. What i've done so far:
1. Create a custom SimpleFeatureType TYPE with a SimpleFeatureTypeBuilder
and add some attributes (some Strings, Integers and finally a Geometry with
Polygons, Multiparts, Linestrings, ect.)
--> builder.add("myattribute", String.class)
builder.build.....
2. Get an instance of GML and write a schema file, something like:
FileOutputStream fos= new FileOutputStream(new
File(c:/test/schema.xsd);
GML enc = new GML(Version.GML2);
enc.setBaseURL(new URL("http://localhost/";));
enc.encode(fos, TYPE);
3. Create a lot of Features and store them in a DefaultFeatureCollection
4. Write the GML of the DefaultFeatureCollection with a new
FileOutputStream.
The .xsd-File contains only the definition for my SimpleFeatureType, but the
(outer) FeatureCollection is missing. If i export the same data with a tool
like Quantum GIS, i get a schema-file which contains my own feature type and
the feature collection. These files also pass validation in most tools. Is
there a mistake in my strategy or is this a known problem? Which strategy
should i use to export a valid .gml- and .xsd-File?
The tool to import the .gml-files is FME Desktop and i'm currently using the
geotools 10.5-release, if that could be part of the problem. Thanks for your
answers, i'm already trying to solve this problem for several hours and have
tried different Versions of GML, but still can't find any solution.
Cheers,
Mark
