Convert NAD83 SRID 8265 to UTM
I have a need to display the UTM values, northing and easting, for coordinates in Australia. The coordinates were collected in NAD 83 and we use SRID 8265 to store the coordinates in an sdo_geometry column.
I know that Australia is in UTM zones 47 to 58. My first thought is that I have to use one of the SDO_CS functions.
My question is how do I know which of the NAD83 UTM SRID's to use?
