I'm sorry to hear that Mapserver has trouble reprojecting stuff that crosses the date line; I had hoped that reprojection would be the panacea. > Is your objective to handle map rendering requests that cross the dateline > for map data that fill the whole -180 to 180 longitude range but stays > within it? I hate to say it, but: We're looking to handle all cases. Some folks have fudged their data to go past the -180/180 box, the majority stay within the -180/180 rectangle. It's meant for general-purpose display, so we can't assume anything about their data except it being in WGS84. You seem to second the advice that pasting together 2 segments is the most flexible approach.
