Dear All,
I have build a data store with CRS (WGS84) containing points displayed
on a DefaultMapLayer.
This works fine with other layers with shapefile, gridcoverage of
different CRS, but, if I want to change the projection for all the
layers, given another CRS, the layer containing the MemoryDatastore is
not reprojected, while this works fine for the other layers
(shapefile,gridcoverage)
Is that due on how I build the FeatureType , featurecollection( I tried
several manners , same result)?
Does that comes from the MemoryDatyaStore( I changed in
CollectionDataStore, same results)?
Does that comes on from how I change the projection on the
DefaultMapLayer ?
Or anything else ? Any idea will be very appreciated.
Many thanks,
Pierre
I work with Geotools 2.4.4
Code to build FeatureType :
public static FeatureType createFeatureType()throws SchemaException {
final AttributeType GEOM =
AttributeTypeFactory.newAttributeType("Location",Point.class,true,
null,null,
Projections.getCRS(Projections.WGS84) );
final AttributeType nom =
AttributeTypeFactory.newAttributeType(s_nompoint,String.class, true );
final AttributeType taille =
AttributeTypeFactory.newAttributeType(s_taille,Double.class );
final AttributeType rotation =
AttributeTypeFactory.newAttributeType(s_rotation,Double.class );
final AttributeType offsetx =
AttributeTypeFactory.newAttributeType(s_offsetx, Double.class );
final AttributeType offsety =
AttributeTypeFactory.newAttributeType(s_offsety, Double.class );
final AttributeType couleur =
AttributeTypeFactory.newAttributeType(s_couleur,String.class );
final AttributeType symbol =
AttributeTypeFactory.newAttributeType(s_symbol,String.class );
final AttributeType référence =
AttributeTypeFactory.newAttributeType(s_référence,String.class );
return FeatureTypeFactory.newFeatureType(new
AttributeType[]
{
GEOM,nom,taille,rotation,offsetx,offsety,couleur,symbol,référence},"Point");
}
code to make transformation for any layer on DefaultMapLayer
FeatureSource fs = getFeatureSource();
String storeTypeName = fs.getDataStore().getTypeNames()[0];
FeatureType schema = fs.getSchema();
CoordinateReferenceSystem crs =
schema.getDefaultGeometry().getCoordinateSystem();
if (crs == null)
{System.out.println ("pas de CRS ");return;}
CoordinateReferenceSystem outCRS =
context.getCoordinateReferenceSystem() ;
DefaultQuery q = new DefaultQuery(storeTypeName);
q.setCoordinateSystem(crs);
q.setCoordinateSystemReproject(outCRS);
setQuery(q);
}
