It can’t hurt, Guy, it can’t hurt!
I would encourage anyone who uses the iMap site and encounters the same problem with image pixelation, that you also write an email to DEP requesting they scan the original glass-plate negatives instead of the screened ones. AFAIK, I don’t think we are talking about a Homeland Security situation here. But, then again, who knows! In order to access ANY aerial photos of the State of Delaware at the State Archives, you must submit your request in writing, have the letter and a photocopy of your driver’s license notarized and then wait for their permission to view the images. And this includes photographs taken in the 1920s and 1930s! Amazing!! Simply amazing!!
