In fact, adding the following code to DefaultCoordinateSystemAxis
fixes the issue (I basically overridden nameMatches to add special
treatment logic to lat/lon axis):
private static List latitudeAliases = Arrays.asList(new String[]
{"Lat", "Geodetic latitude", "Latitude"});
private static List longitudeAliases = Arrays.asList(new String[]
{"Lon", "Geodetic longitude", "Longitude"});
public boolean nameMatches(String name) {
String code = getName().getCode();
if(latitudeAliases.contains(name) &&
latitudeAliases.contains(code))
return true;
if(longitudeAliases.contains(name) &&
longitudeAliases.contains(code))
return true;
return super.nameMatches(name);
}
CRS.equalsIgnoreMetadata now gives me a positive match.
I just don't know if the above is the best way to tackle the problem.
I see there is explicit alias support, but international strings
as coded now pretend to be of the same class to match for equality,
so after a few tests I gave up and went for the easier route.
Cheers
Andrea
