I misplaced my coordinates but I came up with about 60 W 15 S. I remarked to Alice that methods may differ but I didn't think that there would be huge differences in the results. My data source is World Data Bank wdb1.e00 I figure an equal area projection is the appropriate one to use (such as Albers one-sixth rule??) Doesn't Arc/Info's CENTROIDLABELS function move the labels to the polygon centroids? Then project back to geographic??
