All- This morning I was confused by the formatting of lat/lon parameters used in the GDAL pcs.csv file. I initially thought the lat/lon values in the file are standard decimal degrees, until I realized some things weren't adding up. After digging, I learned those params use a "pseudo format" (EPSG:9110). i.e., 45.50 = 45 degrees, 50 minutes *NOT* 45 degrees 30 minutes.
By comparison, the "epsg" file in PROJ.4 stores lat/lon parameters as decimal degrees. I'm sure it's been this way for many years. There must be a reason? Seems like it must lead to a lot of confusion. Thanks for satisfying my curiosity, Jim ---------------------------------------------- Jim Lacy Wisconsin State Cartographer's Office University of Wisconsin-Madison (608) 262-6850 www.sco.wisc.edu<http://www.sco.wisc.edu/> My calendar: http://go.wisc.edu/xziys4
