hey,
unfortunately it is not working. The result looks like this: (the given
resolution was 100m)
0.0, 0.0, 0.0
100.0, 0.0, 0.0
200.0, 0.0, 0.0
300.0, 0.0, 0.0
400.0, 0.0, 0.0
before the resampling it looked like this:
4610500.0, 5675000.0, -5.2
4611500.0, 5675000.0, -5.3
4612500.0, 5675000.0, -5.3
4613500.0, 5675000.0, -5.4
4614500.0, 5675000.0, -5.4
so there is definetly something wrong. but I am not quite sure what it is.
code snippet looks like this:
// set new resolution
scaleX = resolution;
scaleY = resolution;
// create needed transformation
AffineTransform at = AffineTransform.getScaleInstance(scaleX, scaleY);
MathTransform tr = ProjectiveTransform.create(at);
envelope = gc2D.getEnvelope2D();
geometry = new GeneralGridGeometry(PixelInCell.CELL_CENTER, tr, envelope);
// set output CoordinateReferenceSystem
try {
crs_ETRS89_LAEA = CRS.decode("EPSG:3035");
// convert GridCoverage2D to ETRS89_LAEA
gc2DCRSconvert = (GridCoverage2D) Operations.DEFAULT.resample(gc2D,
crs_ETRS89_LAEA, geometry, null);
} catch (NoSuchAuthorityCodeException e) {
// auto-generated catch block
e.printStackTrace();
} catch (FactoryException e) {
// auto-generated catch block
e.printStackTrace();
}
return gc2DCRSconvert;
I am not quite sure about the envelope mentioned in your code. Is it like I
thought?
What now?
