44 | * How to add new Projections:
|

45 | * - Find EPSG code for the projection.

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

55 | * if possible.
