We were informed that support for Modified Azimuthal Equidistant
projections had been added to the latest snapshot of apache sis.
However when we try to create a Modified Azimuthal Equidistant projection
using the following code segments a NoSuchAuthorityCode Exception is thrown
(Is it something we are doing wrong?)
1. Create CoordinateReferenceSystem from code
Code:
CoordinateReferenceSystem crs = CRS.forCode("EPSG:9832");
Exception thrown:
org.opengis.referencing.NoSuchAuthorityCodeException: No
‘CoordinateReferenceSystem’ object found for code “9832” in the “EPSG”
geodetic dataset.

2. Create CoordinateReferenceSystem from wkt
Code:
String wktString = "PROJCS[\"Azimuthal Equidistant
Lng=1.27780675;Lat=58.62877105\","
+ "GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\","
+ "SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],"
+ "PRIMEM[\"Greenwich\",0.0],"
+ "UNIT[\"Degree\",0.0174532925199433]],"
+ "PROJECTION[\"Azimuthal_Equidistant\"],"
+ "PARAMETER[\"False_Easting\",0.0],"
+ "PARAMETER[\"False_Northing\",0.0],"
+ "PARAMETER[\"Central_Meridian\",1.277806753183437],"
+ "PARAMETER[\"Latitude_Of_Origin\",58.62877104866187],"
+ "UNIT[\"Meter\",1.0]]";
CoordinateReferenceSystem crs = CRS.fromWKT(wktString);
Exception thrown:
org.opengis.util.NoSuchIdentifierException: No operation method found for
name or identifier “Azimuthal_Equidistant”.
