Hi all (hi Martin),
sorry to bother, but it seems there are still quite a bit
of issues on 2.3.x with the epsg-hsql module and the new EPSG database.
The following simple WKT encoding app tries to summarize the issues
found scanning epsg-hsql contents. I just developed it inside the
epsg-hsql module for simplicity, without committing it, of course :-):
---------------------------------------------------------------------------
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashSet;
import java.util.Iterator;
import java.util.List;
import java.util.Set;
import org.geotools.referencing.CRS;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
public class WKTLister {
static final boolean printStackTraces = false;
public static void main(String[] args) {
Set codes = CRS.getSupportedCodes("EPSG");
int decodeExceptions = 0;
int wktExceptions = 0;
Set exceptions = new HashSet();
for (Iterator it = codes.iterator(); it.hasNext();) {
String code = (String) it.next();
CoordinateReferenceSystem crs = null;
try {
crs = CRS.decode("EPSG:" + code);
} catch (Exception e) {
decodeExceptions++;
System.out.println("Issues decoding EPSG:" + code + ". ");
if(printStackTraces) e.printStackTrace();
exceptions.add(e.getMessage());
}
if(crs != null)
try {
crs.toWKT();
} catch(Exception e) {
wktExceptions++;
System.out.println("Issues converting EPSG:" + code
+ " in WKT format.");
if(printStackTraces) e.printStackTrace();
exceptions.add(e.getMessage());
}
}
System.out.println("Total codes: " + codes.size());
System.out.println("Decode exceptions: " + decodeExceptions);
System.out.println("Wkt encode exceptions: " + wktExceptions);
List exceptionList = new ArrayList(exceptions);
Collections.sort(exceptionList);
System.out.println("Unique exceptions found: " +
exceptions.size());
for (Iterator it = exceptionList.iterator(); it.hasNext();) {
System.out.println(it.next());
}
}
}

The summary output is:

Decode exceptions: 157
Wkt encode exceptions: 240

I separated WKT encoding issues because Geoserver is
using toString() now, and in the single exceptions list
there are quite a bit of things that cannot be fixed
in 2.3.x, such as missing projections, yet a few seem
to be missing aliases or issues with unit conversion.
Can you look into this Martin?
Cheers
Andrea
