Hi Michelle,
You're not seeing Altitude, Latitude or Longitude because
they are CoordinateSystem reference types, which
DataUtility.getScalarTypes does not extract by default.
However, you can extract them by passing in coordSys=true to
getScalarTypes. Also, I recommend using keepDupl=false, so
that you don't receive the same RealTypes multiple times.
Try the following code:
Data[] myData = mySS.DisplayCells[width][height].getData();
Vector myVector = new Vector(10);
DataUtility.getScalarTypes(myData, myVector, false, true);
for (int i = 0; i < myVector.size(); i++) {
ScalarType st = (ScalarType) myVector.elementAt(i);
System.out.println("type #" + i + " = " + st);
}
If the above code doesn't get all the ScalarTypes, it's
probably a bug in getScalarTypes, and I'll look into it.
