示例1: geometryToGeoJson
import org.wololo.jts2geojson.GeoJSONWriter; //導入依賴的package包/類
public static ClobType geometryToGeoJson(GeometryType geometry)
throws FunctionExecutionException {
Geometry jtsGeometry = getGeometry(geometry);
GeoJSONWriter writer = new GeoJSONWriter();
try {
GeoJSON geoJson = writer.write(jtsGeometry);
ClobType result = new ClobType(new ClobImpl(geoJson.toString()));
result.setType(Type.JSON);
return result;
} catch (Exception e) {
throw new FunctionExecutionException(e);
}
}
示例2: transformGeometry
import org.wololo.jts2geojson.GeoJSONWriter; //導入依賴的package包/類
/**
* Transforms geojson geometry between different formats. Usage example:
* <pre>
* FeatureCollection featureCollectionIn3857 = ... //e.g. from the route service
* //Preparing transformer
* CoordinateReferenceSystem sourceCRS = CRS.decode("EPSG:3857"); //Web Mercartor
* CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:4326"); //WGS84
* MathTransform transformer = CRS.findMathTransform(sourceCRS, targetCRS);
* //Do transformation from EPSG:3857 (Web Mercartor) to EPSG:4326 (WGS84)
* FeatureCollection featureCollectionIn4326 = new FeatureCollection(
* GeojsonUtil.transformGeometry(featureCollectionIn3857,transformer).toArray(new Feature[0]));
* </pre>
*
* @param transformer transformer initialized with the correct formats
* @param featuresToTransform features that need to be transformed into the target format
* @return Zero or more transformed geometry features
* @throws TransformException if the geographic projection transformation fails
