Hi,
I am trying to create a litle tool to set the projection on shapefiles that don't have their projection info set.
I know what the projection is and theirfore I don't need to reproject.
I've tried the samples available in the wiki with no success.
Basically I just want to update the existing shapefiles with the appropriate CRS. I don't really need to create new ones.
Is there a simple way to do this ?
The code below seems to simply copy my shapefiles to a different directory. Their projection info doesn't seem to have changed ...
ShapefileDataStore dataStore = new ShapefileDataStore(inputFile.toURI().toURL());
String[] typeNames = dataStore.getTypeNames();
String typeName = typeNames[0];
DefaultQuery q = new DefaultQuery();
q.setCoordinateSystem(originCrs);
System.out.println("Reading content " + typeName);
FeatureSource<SimpleFeatureType, SimpleFeature> featureSource = dataStore.getFeatureSource(typeName);
SimpleFeatureType simpleFeatureType = featureSource.getSchema();
System.out.println("Header: " + DataUtilities.spec( simpleFeatureType ));
File resultFile = new File( destFolderPath + children[i]);
FeatureCollection<SimpleFeatureType, SimpleFeature> collection = featureSource.getFeatures(q);
DataStoreFactorySpi factory = new ShapefileDataStoreFactory();
Map<String, Serializable> create = new HashMap<String,Serializable>();
create.put("url", resultFile.toURI().toURL());
create.put("create spatial index", Boolean.TRUE);
DataStore newDataStore = factory.createNewDataStore(create);
newDataStore.createSchema(collection.getSchema());
Transaction transaction = new DefaultTransaction();
FeatureStore<SimpleFeatureType, SimpleFeature> featureStore;
featureStore = (FeatureStore<SimpleFeatureType, SimpleFeature>) newDataStore
.getFeatureSource(typeName);
featureStore.setTransaction(transaction);
try {
featureStore.addFeatures(collection);
transaction.commit();
} catch (Exception problem) {
problem.printStackTrace();
transaction.rollback();
}
finally {
transaction.close();
}
Many thanks for your help.
