Hello lists,
The gpx module in geotools 2.5-M3 create an empty database with
(track,point,waypoint) and can't parse correctly the gpx file,is these
caused by the xml parser of geotools ?
-Can't support CDATA tags in gpx file.
-Can't support of extention.
This is my test code :
import java.io.File;
import java.io.IOException;
import java.net.URL;
import org.geotools.data.DataStore;
import org.geotools.data.FeatureSource;
import org.geotools.data.gpx.GpxDataStoreFactory;
import org.geotools.feature.FeatureIterator;
import org.opengis.feature.Feature;
import org.opengis.feature.simple.SimpleFeature;
import org.opengis.feature.simple.SimpleFeatureType;
public class GpxDataStore {
public static void main(String[] args) throws IOException {
File gpx = new File("/home/../Desktop/a.gpx");
URL url = gpx.toURI().toURL();
System.out.println(url.toExternalForm());
DataStore store = new GpxDataStoreFactory().createDataStore(url);
FeatureSource<SimpleFeatureType, SimpleFeature> points = store
.getFeatureSource(org.geotools.data.gpx.GpxDataStore.TYPE_NAME_POINT);
FeatureIterator<SimpleFeature> it = points.getFeatures().features();
int cnt = 0;
while (it.hasNext()) {
Feature f = it.next();
System.out.println(f);
String[] typeNames = store.getTypeNames();
System.out.println(typeNames[1]);
cnt++;
}
}
}
