Nice, but there should be a higher resolution version of this right?  I know it is redundant with [[:Image:OldPensacolaAerial.jpg]] but the latter does not have the detail at the bottom.  '''[[User:Dcosson|dcosson]]''' ··· '''[[User talk:Dcosson|talk]]''' 16:07, 21 April 2007 (CDT)

: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)
 
::::Oh definitely.  The TIFF was about 133 MB.  JPEG compressed to 80% was 12.5 MB, site wouldn't take it;  JPEG @ 60% compression was 8.5 MB, site wouldn't take it.  I finally got a 50% compressed JPEG (7.1 MB) to upload.  [[:Image:WellgeMapHR.jpg]].
