Hello,
I read Hebrew (Bible translator and have studied scrolls extensively), and can tell you for certain that this is a portion of a Torah scroll. From the photo details it does look like a legitimate scroll, although fakes are possible. Specifically, what you have that is visible to the eye is part of Genesis. From the top of the text closest to the rolled section, it begins with Genesis 41:46, and ends at the bottom of the scroll at the beginning of Genesis 44:22. If what you have is legitimate, it is probably worth more for what it is than any map that it might contain.
Any further details would be helpful to establish provenance if the map has anything to do with the locale of where it originated.
