The provider for "Modified Azimuthal Equidistant" projection (EPSG:9832).
Relationship with "Azimuthal Equidistant"
The Modified Azimuthal Equidistant projection is an approximation of a theoretically more generic oblique Azimuthal Equidistant projection. But Snyder's Map Projection — a working manual book actually gives formulas for the same scope than the one given by EPSG, namely for islands in Micronesia. Consequently, we assume that what is commonly presented by other libraries as a "generic" Azimuthal Equidistant projection is actually the Modified Azimuthal Equidistant approximation.- Since:

erase
private static ParameterBuilder erase(ParameterBuilder builder, org.opengis.parameter.ParameterDescriptor<?> template) Returns a parameter with the same names and identifiers than the given parameter, except (OGC), ESRI and netCDF names which are omitted. We omit those names for now because we have not seen a reference about what those parameter names should be. The OGC names are kept despite that because it uses the same names for most projection. This may be revisited in future SIS versions.The OGC and GeoTIFF names kept by this method are actually the names for Azimuthal Equidistant (not modified) projection.
