Hi- I have a a near global 30 arcsecond dataset I would like to serve through WMS and WCS. However, it seems that no matter what I try it is being dealt with in degrees (0.00833333) and not seconds. Is there a way to specify seconds in the mapfile are use gdal to do this? I notice in the mapfile reference that seconds is not an option for Units. The problem I am having with using degrees is serious rounding errors in the pixel sizes of the returned images. It seems that mapserver is doing a string to float conversion on 0.0833333 and then doing math with that float and this is causing the output image to have incorrect pixel sizes. It seems that if I could use seconds (which would mean I'd have a round number for my units instead of a repeating decimal) that this problem would be solved. I haven't found a way to do this though.
Ben, There is no way to operate in arcseconds with mapserver - sorry. I'd be interested in knowing more about what is getting rounded improperly, and how you are specifying the values. Are you using a world file? Is it the DescribeCoverage that is coming back rounded improperly?
