Unable to use South Pole projection with Proj.4 plugin

[jochen@…]

What steps will reproduce the problem?

1. Install Proj.4 plugin
2. Switch to EPSG:3031 projection
3. Load Antarctica data (​http://download.geofabrik.de/openstreetmap/antarctica.osm.bz2)

What is the expected result?

Should show Antarctica data in EPSG:3031

What happens instead?

Crash

For a correct representation of EPSG:3031, I went to ​http://jira.codehaus.org/browse/GEOS-3761

Enabling wireframe mode disables those exceptions, but the Antarctica isn't displayed at all.

I guess this problem isn't due to the proj4j plugin, but related to the rendering code. I'm not familiar with that part of JOSM, though.

[Don-vip]

The rendering code is not guilty, it's because NavigatableComponent.getDist100Pixel() returns 0.0.

I don't know why, yet.

[simon04]

Could that be due to the meridians all joining in one point (south pole) …?

[Don-vip]

Maybe. Thid method does not seem to work with this projection:

    public LatLon eastNorth2latlon(EastNorth p) {
        org.osgeo.proj4j.ProjCoordinate pc1 = new org.osgeo.proj4j.ProjCoordinate(p.east(), p.north());
        org.osgeo.proj4j.ProjCoordinate pc2 = new org.osgeo.proj4j.ProjCoordinate();
        System.out.println("InvFrom " + pc1.x + " " + pc1.y);
        transformToWGS84.transform(pc1, pc2);
        System.out.println("InvTo " + pc2.x + " " + pc2.y);
        return new LatLon(pc2.y, pc2.x);
    }

InvFrom -9.220318685515014E-11  -1666567.013815138  => InvTo -180.0 -74.74854322089772

In 5753/josm:

see #8485 - Don't throw IllegalArgumentException with buggy projections

[Don-vip]

Proj4j code has evolved, we have the revision 2150, current is 2285, let's see if upgrading it resolves this issue.

[Don-vip]

Updated in [o29325] but bug still here :(

[Don-vip]

The plugin has been deprecated, most of its projections are now in JOSM core.
