             Summary: convertLatLon swaps coordinates
                 Key: JENA-2266
                 URL: https://issues.apache.org/jira/browse/JENA-2266
             Project: Apache Jena
          Issue Type: Bug
          Components: GeoSPARQL
    Affects Versions: Jena 4.3.2
            Reporter: Claus Stadler


The correct setting is that longitude corresponds to x-axis and latitude to y-axis, but in the code lat is passed for x and lon for y.

{code:java}
public class ConvertLatLon {
    public static final Literal toLiteral(double lat, double lon) {
        checkBounds(lat, lon);
        return WKTLiteralFactory.createPoint(lat, lon, SRS_URI.WGS84_CRS);
    }
}
{code}

{code:java}
public class WKTLiteralFactory {
    public static final Literal createPoint(Double x, Double y, String srsURI) {
        String tidyURI = tidySrsURI(srsURI);
        return ResourceFactory.createTypedLiteral(tidyURI + "POINT(" + reducePrecision(x) + " " + reducePrecision(y)
 + ")", WKTDatatype.INSTANCE);
    }
}
{code}
