Yeah... There is unfortunatly no API right now for fetching the EPSG code from
a
WKT, so looping over all possible CRS is the only way currently provided.
However if we want to check by CRS name only, then instead of:
>> CoordinateReferenceSystem crs =
>> crsfactory.createCoordinateReferenceSystem(str);
The following will be more lightweight, since it just fetch the name without
creating a full CRS object:
String name = crsFactory.getDescriptionText(str);
In long term, we need to provide a way that use SQL queries in order to search
efficiently for a CRS in the EPSG database. It would probably need to be a
brand
new class instead of an extension of existing classes.
