:I tried to grab the whole thing from the Library of Congress file, but unlike the other maps, which are JPEG2000 format, this one was in a strange format called "MrSID". I found a reader, but it will only let me export one screen's worth at a time. Rather than spend hours to export the whole thing piece by piece and tile them all together, I figured this was a reasonable compromise until we can find something better.--[[User:Admin|Admin]] 17:17, 21 April 2007 (CDT)
::Yeah, MrSID sucks. I've taken the MrSID image, exported it to TIFF, and then to JPG. It's an pretty large file at 8+ MB, but I didn't want to compress it too much for quality's sake. Right now it's compressed at 60% quality of the source TIFF... but I am having trouble uploading it. '''[[User:Dcosson|dcosson]]''' ··· '''[[User talk:Dcosson|talk]]''' 18:55, 21 April 2007 (CDT)
:::TIFFs are really huge files. A high-quality JPEG will lower the filesize dramatically without being too lossy.--[[User:Admin|Admin]] 19:04, 21 April 2007 (CDT)
