It seems to me that the NAD83 (which stands for North American Datum at 1983)format you are quoting is simply stating the Lat and Long in decimal degrees. The Lat and Long you quote is equivalent to Lat 33 Deg 53 Mins and 17.4192 seconds. The Long is -118 Deg 20 Mins and 53.9808 seconds. This can be achieved by first multiplying the first fraction by 60. The whole number of the result is the minutes. You then multiply the resultant fraction by 60 and the next whole number is the seconds. Any good GPS unit should be able to convert decimal degrees into minutes and seconds. By the way the minus sign indicates that the longitude is west of Greenwich with it being at zero degrees. I hope that helps. -- Stuart Perth Western Australia Enter the drawing for a FREE Legacy Cruise to Alaska or a FREE research trip to Salt Lake's Family History Library.
