I found a bunch of old files with the extension ".cor" and ".ssf". They appear to be shots on section corners done with - what I think is - an old TSC1 and a backpack style GPS. I can't open them but in notepad, some of them have (among garbled characters) the heading "Asset Surveyor version 4.03".
Does anyone have experience with these files - what are they and how were they collected? How can I import them into some kind of readable format?
The .pdf is too large to load here, but this link should get you there (although I don't know if it will help).
