Happy New Year to all! I've got a frustrating problem. I've created a Java
application that reads in data from a GeoTiff and then finds points on that
GeoTiff by converting a Lat/Long coordinate into the local coordinates in
the GeoTiff. This is accomplished by reading the CRS from the GeoTiff and
building a MathTransform between that and Lat/Long using the following
lines:
//Get the native coordinate system from the GeoTiff file
this.CRSin = reader.getCoordinateReferenceSystem();
//This is the standard WGS 84 CRS
CoordinateReferenceSystem latlongCRS = CRS.decode("EPSG:4326 ");
//WGS 84 Lat/Long
//Create the transform from the GeoTiff CRS to Lat/Long
this.LatLong2tif = CRS.findMathTransform(latlongCRS, this.CRSin,
true);
I have managed to convert my local java app into a server based app. 99% of
the code is exactly the same, including all aspects of dealing with the
coordinate transform. However, when the code runs on the server, it chooses
a different (and clearly incorrect) MathTransform. I've tried to debug this
all the way down to the CRS class, but I can't figure out why it should do
something different.
Both versions correctly identify both CRSs and pass along the exact same
inputs to find the MathTransform, but they produce different results. Has
anyone seen this problem?
