Message:

Specify +axis=neu for Austrian projections

This allows to use the following WMTS in JOSM:

• ​https://gis.ktn.gv.at/arcgis/rest/services/tilecache/Ortho_2013_2015/MapServer/WMTS/
• ​https://service.salzburg.gv.at/arcgis/rest/services/Orthofoto_Land_Salzburg/MapServer/WMTS/

File:

• trunk/src/org/openstreetmap/josm/data/projection/CustomProjection.java (modified) (2 diffs)

+     * Starting in PROJ 4.8.0, the {@code +axis} argument can be used to control the axis orientation of the coordinate system.
+     * The default orientation is "easting, northing, up" but directions can be flipped, or axes flipped using
+     * combinations of the axes in the {@code +axis} switch. The values are: {@code e} (Easting), {@code w} (Westing),
+     * {@code n} (Northing), {@code s} (Southing), {@code u} (Up), {@code d} (Down);
+     * Examples: {@code +axis=enu} (the default easting, northing, elevation), {@code +axis=neu} (northing, easting, up;
+     * useful for "lat/long" geographic coordinates, or south orientated transverse mercator), {@code +axis=wnu}
+     * (westing, northing, up - some planetary coordinate systems have "west positive" coordinate systems)
