I'd like to contribute changes to
org.geotools.process.raster.GridConvergenceAngleCalc that do two things:
1) makes the class public
2) fixes determineUpAxisDimension method and allows it to work with more
projections. (I believe its approach to using AxisDirection for determining
the screen up axis was incorrect.)
Is there interest in a pull request? It passes existing unit tests but I
intend to add additional ones. I do not have a separate utility that
calculates convergence angle for points in arbitrary CRSs but if anyone does
and cares to provide some test vectors that would help. Otherwise I may need
to calculate them by hand.

Subject: [EXTERNAL] [Geotools-gt2-users] RasterAsPointCollectionProcess Grid
Convergence Calculation question
Hello.
I'm looking for insight on the purpose and use of
org.geotools.process.raster.RasterAsPointCollectionProcess's Grid Convergence
Angle calculation capability. I am interested in a capability that adds GCA
attribute to all features output from RasterAsPointCollectionProcess and
thought supplying a targetCRS argument would do just that but it doesn't do
what I expect and left me wondering just what its intended use is. Here's how
it appears to work. Presence of targetCRS argument informs the process to
calculate GCA at each point after reprojecting it into the targetCRS, but only
if targetCRS is effectively different than the input GridCoverage2D's CRS. Why
not calculate the GCA anyway? Sure, the reprojection wouldn't be necessary but
there could still be a GCA.
As a follow-up question, I'd like to reuse
org.geotools.process.raster.GridConvergenceAngleCalc class in a Rendering
Transform since RasterAsPoint doesn't do what I need but it's package private.
Is there chance I could of get this moved to public? I would also want to do
some work on its determineUpAxisDimension() method to make it work with more
projections.
Thanks,
Tom
