49 * Projection preferences.
50 *
51 * How to add new Projections:
52 * - Find EPSG code for the projection.
53 * - Look up the parameter string for Proj4, e.g. on http://spatialreference.org/
54 * and add it to the file 'data/projection/epsg' in JOSM trunk
55 * - Search for official references and verify the parameter values. These
56 * documents are often available in the local language only.
57 * - Use {@link #registerProjectionChoice}, to make the entry known to JOSM.
58 *
59 * In case there is no EPSG code:
60 * - override {@link AbstractProjectionChoice#getProjection()} and provide
61 * a manual implementation of the projection. Use {@link CustomProjection}
62 * if possible.
