[PATCH] Polish official coordinate systems (EPSG 2176 through 2180)

[steelman]

The patch implements EPSG:2176 though 2180, the official projections in Poland. They use the same maths as UTM but with different constants.

The classes also implement eastToString(EastNorth p) and northToString(EastNorth p) formatting methods with appropriate precision settings. Currently these stay unused.

Polish official coordinate systems.

In case you wonder - there is a reason why this is not yet checked in. JOSM projection stuff will change a bit, so that each projection learns to have settings or subprojections. This will prevent these many Epsg-files you patch contains.

I hope it is not going to be a tough task to rewrite my work?

[stoecker]

In r2272 I checked in the general structure for the new sub-prefs. Maybe you can change your code accordingly (and possibly fix some of the TODO's as well :-)

Mainly it is now that you have 1 projection which allows to have sub-projections (or preferences).

[stoecker]

The sub projections stuff has improved a lot now. When you want the polish coordinate system to be in next tested, then now would be the right time to improve your patch.

PUWG patch for revision 2500

[steelman]

The new patch is ready. The structure of the code hasn't changed much but there is an interface to select a zone. I've also introduced a nasty hack with latlon2eastNorth and eastNorth2latlon returning null in two sub classes because the calculations are in the superclass. However, the subclasses still need to implement projection for other methods. If you consider the hack too nasty I'll try to fix it.
