Thanks, I change the prj file, the way ESRI wants it, when the export is done. Ihave 5 hard coded prj configurations for the 5 projections I use, in the java program.

I thought there was a flag you could pass to the ShapefileWriter to set that up but I can't see it on a quick look. Alternatively, you could open a bug report with ESRI asking them to support the standard better.

It seems that Arc Gis don’t understand that the prj file describes the wgs84 projection, but funny enough ArcGis understands it when it should project the file! ArcGis prj file is not the same as my prj file, but the result of the description in the prj files is the same. The result when importing the wgs84 shape file is still correct when it is imported and projected to wgs84. It is really annoying to have to reproject to the same projection when importing to ArcGis. Is there anyone who has an solution for this? I’m using the following example code: private void exportLayer(String layerName, File directory) throws IOException { SimpleFeatureSource featureSource = MainDialog.getDataStore().getFeatureSource(layerName); SimpleFeatureType ft = featureSource.getSchema(); String fileName = ft.getTypeName(); File file = new File(directory, fileName + ".shp"); Map<String, java.io.Serializable> creationParams = new HashMap<>(); creationParams.put("url", URLs.fileToUrl(file)); FileDataStoreFactorySpi factory = FileDataStoreFinder.getDataStoreFactory("shp"); DataStore dataStore = factory.createNewDataStore(creationParams); dataStore.createSchema(ft); // The following workaround to write out the prj is no longer needed // ((ShapefileDataStore)dataStore).forceSchemaCRS(ft.getCoordinateReferenceSystem()); SimpleFeatureStore featureStore = (SimpleFeatureStore) dataStore.getFeatureSource(layerName); Transaction t = new DefaultTransaction(); try { SimpleFeatureCollection collection = featureSource.getFeatures(); // grab all features featureStore.addFeatures(collection); t.commit(); // write it out } catch (IOException eek) { JOptionPane.showMessageDialog(null, eek.toString()); eek.printStackTrace(); try { t.rollback(); } catch (IOException doubleEeek) { // rollback failed? } } finally { t.close(); } MainDialog.removeDataStore(); } Kind regars, Paul _______________________________________________ GeoTools-GT2-Users mailing list GeoTools-GT2-Users@lists.sourceforge.net<mailto:GeoTools-GT2-Users@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users -- Ian Turton _______________________________________________ GeoTools-GT2-Users mailing list GeoTools-GT2-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users
