Re: [Geotools-gt2-users] MathTransform changes on app type

Fri, 06 Jan 2017 09:01:22 -0800 

Jody,



                You are my new favorite person. I’m attaching the two
outputs from the server and application versions of this project. The
server version is clearly different. Anyone have a clue how to make the
server version behave?

I have not seen this problem on a server; but did run into a similar
problem when working on an OSGi desktop appl



There is however a magic "what the heck is going on" call you can make to
print out what factories are available and what priorities they have. Let
me find the snippet - it prints a tree out of what is going on.

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?
