1. The default input format has X (easting) followed by Y (northing). You need to use the -r switch if the northing comes first.
Glynn, That's what I thought. I tried the '-r' switch, too, based on the example in the man page. Originally I had the easting first but changed to match the man page example. It is the explanation below that was the real source of my issues with the tool.
2. In the absence of a trailing E or W, positive eastings are east of the prime meridian. You need either a leading "-" or a trailing "W" for eastings in the western hemisphere.
This is where I went off the tracks. I kept looking at the example in the man page and saw the different formats. However, what I saw was that thowe with a leading '-' or trailing 'W' were expressed in decimal degrees, not degrees-minutes-seconds. Based on that I did not use either the prefix or suffix since my values are in DMS. Thank you very much for clarifying. The man page is ambiguous and when used as a learning tool rather than a reference leads to invalid results. Very much appreciated, Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
