Creating GTIFF dataset with arc-second geounits

[ccjklppp]

Hi,

I'm trying to copy a dataset with geounits='arc-second' and it doesn't work appropriately. It seems that there is a problem creating GTIFF dataset with other than 'Degree' geounits.

I've made some changes in gt_wkt_srs.cpp file to make it work. can u please add the changes to the source control..?

I added the following code where the GeogAngularUnitsGeoKey is written:

else if (EQUAL(angUnitName, "arc-second"))
		GTIFKeySet(psGTIF, GeogAngularUnitsGeoKey, TYPE_SHORT, 1,
			Angular_Arc_Second);

(the full gt_wkt_srs.cpp file is attached)
