Hello, Although all the cartographic testing has been done, I just tested for the first time upgrading 4.8.1 to 5.0.2 with my JavaScript mapping UI, and have discovered something troubling:
For a given map file, the final extent and scale calculations are different between the two versions! For the same mapfile "105.map" with: EXTENT -2750564.75 -936638.5 3583872.5 4673125 With 4.8.1: http://atlas.nrcan.gc.ca/cgi-bin/mapserv?map=/home/atlas/mapdata/english/105.map&map_web_template=/home/atlas/mapdata/to_zope_new.html&mapsize=428+380&map_scalebar_imagecolor=255+255+255 -2750564.750000 -943773.286215 3583872.500000 4680259.786215 41953025.267029 With 5.0.2: http://dev.atlas.gc.ca/cgi-bin/mapserv502atlas?map=/home/atlas/mapdata/english/105.map&map.web=TEMPLATE+/home/atlas/mapdata/to_zope_new.html&mapsize=428+380&map.scalebar=COLOR+255+255+255 -2750564.750000 -942941.431206 3583872.500000 4679427.931206 42051275.911682 That scale change is big enough to break all our min/max scale ranges and so on :( (on hundreds of mapfiles) I've looked through HISTORY.TXT and the Migration Guide but am not seeing anything about this (All I saw was a change in scale calculation for PHP?) Help?
