问题
I have a java geotools program to convert a coordinate between two coordinate systems. It attempts to convert between coordinate system ESPG:4326 and ESPG:5179.
I receive the following exception when trying to execute this line in my code:
CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:4326");
Exception in thread "main" org.opengis.referencing.NoSuchAuthorityCodeException: No code "EPSG:4326" from authority "EPSG" found for object of type "EngineeringCRS".

My test program:
import org.geotools.geometry.jts.JTS;
import org.geotools.referencing.CRS;
import org.locationtech.jts.geom.Coordinate;
import org.opengis.referencing.FactoryException;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
import org.opengis.referencing.operation.MathTransform;
import javax.xml.crypto.dsig.TransformException;
public class main {
public static void main(String[] args) throws Exception {
CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:4326");
CoordinateReferenceSystem sourceCRS = CRS.decode("EPSG:5179");
double coordinateX = 1307285;
double coordinateY = 2229260;
Coordinate in = new Coordinate(coordinateX, coordinateY);
Coordinate out = in;
MathTransform transform = CRS.findMathTransform(sourceCRS, targetCRS);
Coordinate result = JTS.transform(in, out, transform);
result.toString();
}
}
My build.gradle:
plugins {
id 'java'
}
repositories {
flatDir {
dirs 'libs'
}
maven {
url "http://download.osgeo.org/webdav/geotools/"
}
mavenCentral()
}
dependencies {
implementation group: 'org.geotools', name: 'gt-main', version: '20.2'
implementation('org.geotools:gt-referencing:20.2') {
exclude group: 'javax.units', module: 'jsr108'
}
files('libs/js4108-0.01.jar')
}
I thought it was sufficient to depend on gt-main
and gt-referencing
.
回答1:
I needed to add the following dependencies
implementation group: 'org.geotools', name: 'gt-epsg-hsql', version: '20.2'
implementation group: 'org.geotools', name: 'gt-epsg-extension', version: '20.2'
This is documented in geotools referencing documentation
