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