Re: [Geotools-devel] cts debugging help

[Rueben S. <r_j...@ya...>]

Hi,

I doubt I know enough about the design, at present, to contribute much.
What I did do was trace out how CoordinateTransformationFactory decides
which transforms to use and how these equations are applied.

The one thing that did (and still does a bit) confuse me when I started
learning cts were the adapters. This is discussed in the design
document, but made more sense to me when I found an older email
discussing them. It that email, Martin gave 3 lines of code to create a
org.opengis interface. They were:

Ellipsoid e = CoordinateSystemFactory.createEllipsoid(...);
CS_Ellipsoid oe = Adapters.export(e);
e = Adapters.wrap(oe);
