Hello All,
I have received numerous MrSid images (historic aerial photographs - geo-referenced, most probably).
When I open them in ArcMap (or ERDAS Imagine), they are not projected and without any projection information.
I tried to look for header or other files and none are present. The image information likewise yields a blank for coordinate system.
Can anyone provide some insights? Does the compression has something to do with this?
thanks,
Samuel
